In this study, three-electrode based electric cell-substrate impedance sensing ECIS devices were used to study the electrical properties of blood and its constituents using electrochemical impedance spectroscopy. The three-electrode based ECIS devices were fabricated by using micromachining technology with varying sizes for working, reference and counter electrodes. The blood and its constituents such as serum, plasma, and red blood cells RBCs were prepared by conventional methods and stored for impedance measurement using fabricated microdevices.

Equivalent circuits for blood, serum, plasma and RBCs were proposed using the software package ZSimpWin to validate the experimental data. The proposed equivalent circuit models of blood and its components have excellent agreement up to a frequency of 1 MHz. It is evident from the experimental results that blood and its components have specific impedance signatures that decrease with the increase of frequency.

It was also found that above rhe kHz, the impedance value of RBCs is nearly the percetage as whole blood. The impedance of serum and plasma steadily decreases with the increase of frequency up to kHz and flattens out after that. The minimum impedance value achieved for serum and plasma is much less than the value obtained for whole blood. Blood is an important functional body fluid that transports oxygen as well as nutrients, vitamins, and metabolites to each part of the body.

Blood is a heterogeneous tissue consisting of plasma, serum, and different blood cells such as red blood cells RBCswhite blood cells WBCsand platelets perventage of which have pdrcentage functions and structures. Therefore precise knowledge what is the percentage of water in human blood physical, biological, chemical, and electrical properties of blood and its constituents is of great importance in medicine and biology [ 1 ].

The investigation of haematological and biochemical parameters of blood are studied by microscopy of blood cells, automated blood cell shat, and routine biochemical techniques, which are labor-consuming and expensive [ 123 ]. Thus to overcome the above shortcomings, bioimpedance spectroscopy has been used to study the are there a lot of fake accounts on tinder parameters of blood such as glucose [ 4 - 5 ], urea [ 6 - 7 ], lactate [ 8 - 9 ], cholesterol [ 10 - 11 ], nitric oxide [ 12 ] etc.

Whaf the what is the main purpose of external marketing activities characterization of blood and its components are essential to study different biomedical applications, such what is the percentage of water in human blood the separation of whxt cells from normal blood cells [ 13 - 14 ], deterioration of preserved blood [ 15 ], and dielectric coagulometry [ 16 ].

The bioimpedance spectroscopy method has been used for decades to investigate the electrical properties of cell and tissue because of its several advantages including its low cost, ease of application, noninvasiveness, and capability for online monitoring [ 17 ]. Also the sample volumes required by microelectrodes realised by percejtage techniques in recent decades are reduced compared to macroelectrodes.

Thus this dispersion is physiologically significant and it arises within the range of 1 kHz to 10 MHz. Also contact of the electrodes with the biological tissue leads to electrochemical phenomena that introduce additional impedance known as polarisation impedance to the system [ 19 ]. This well-known phenomenon is specific for a given electrode-electrolyte interface, with the potential due to the polarisation impedance dependent upon the metalelectrolyte combination, current density, and frequency [ 20 ].

In the present work several ECIS devices having different dimensions are fabricated by micromachining techniques and used to study the electrical properties of blood and its constituents serum, plasma and RBCs. The commercially available ECIS device 8W1E, Applied Biophysics has a smaller sensing electrode than the reference electrode RE and produces an excellent result in the higher frequency range. However, in lower frequency ranges, the polarisation effect of eprcentage electrode incorporates noise into the measurement due to formation of double layer capacitance between the charged electrode surface and the available ions in the surrounding electrolytic solution [ 20 ].

This effect is prominent for biological baby loves tacos meyran due to the high conductivity of its buffer solution. To avoid the undesirable drifting of electrode potential, three-electrode techniques are adopted for the present ECIS device study. Incorporation of a reference electrode will measure the working electrode WE potential, independent of charges that occur at the counter electrode CE.

Mishra et al. For the present design, the authors kept the WE and What is the percentage of water in human blood ratio at 0. Brett and Brett [ 22 ] have shown that the surface area ratio of CE and WE should be larger than 10 in order to support the what restaurants accept ebt cards generated at the WE.

The ratio is kept at in the present design of ECIS devices. The details of the schematic drawing of electrodes for a single device is given in Fig. The ECIS devices were fabricated on 2 inch diameter Pyrex wafers using metal deposition and photolithography techniques. Initially, the wafers were cleaned and thin layers of chromium Cr and gold Au were thermally evaporated onto the wafers. Subsequently, the electrode watr and its contact pads were lithographically defined using a positive photoresist and the Cr and Au layers were selectively removed by a wet etching process to define the metal patterns on the substrate.

Finally, a second lithography step was performed to apply another photosensitive polymer SU8 layer as a passivation coating over the percengage electrodes. In this step, only the electrode sensors and contact pads were exposed to make contact with the electrolyte as shown in Fig. The photoresist was hard baked to impart stability and inertness to the polymer.

The wafers were then diced into single devices for subsequent packaging and measurements. Finally, the individual device was fixed within a printed circuit board and electrical connections were taken from the device to external equipment using thin metal wires. Cloning cylinders were then aligned and wuat to serve as an electrolyte reservoir around the three-electrode system by perventage PDMS as glue.

To prepare the serum, the collected whole blood was kept in a test tube for minutes and allowed to clot. The resulting supernatant serum was stored in room temperature for impedance measurement [ 26 ]. To prepare the RBC and plasma, the collected human whole blood was kept in test tube with an anticoagulant dipotassium ethylenediamine-tetraacetic acid K 2 EDTA, 1. The centrifuged what is the percentage of water in human blood forms three layers from top to bottom namely: plasma, leucocytes, and erythrocytes.

The resulting supernatant is aspirated carefully and stored at room temperature for impedance measurement. The erythrocyte pellets were collected what is the percentage of water in human blood washed two times with PBS and stored in PBS for further impedance measurement [ 27 ]. The electrical impedance measurements of percsntage and its constituents were carried out using a computer controlled electrochemical workstation SP Bio-Logic, France by connecting the fabricated device directly to the system.

Initially, however, the electrodes of all designs were dipped in PBS pH 7. All the measurements were performed with an actuation voltage of 10 mV and frequency range from Hz to 1 MHz with 51 sample points in between in a logarithmic scale. All the measurements were repeated ten times and then averaged to get the impedance value for each frequency. The aforementioned electrochemical workstation has a built-in facility to reduce the noise margin of the measured impedance data through software interpretation.

The Nyquist data was obtained from the four designed devices and subsequently exported to ZsimpWin software for further analysis with what is the percentage of water in human blood circuit simulation. Various electrical parameters of the equivalent circuit model were extracted by iterative processes for analysis of the impedance characteristics for various components of blood samples with relative standard error. The impedance spectroscopy data found from experiment was imported to ZsimpWin version 3.

The modelling was performed by an iterative process. The equivalent circuit adopted teh this study is comprised of a constant phase element CPEQ Sthat represents interface capacitance shunted by a charge transfer resistance, R CTtogether in series with the solution resistance, R S. A good agreement between experimental and simulated results was observed.

This result is also comparable with previous literature [ 30 - 31 ]. From Fig. In the present experiment, only one dispersion in the frequency range up to 10 kHz is found, as shown in Fig. At lower frequencies, the membrane effectively insulates the cytoplasm and current can only flow around the cells, but as frequency increases, the cell membrane becomes more conductive and current can pass through the cells.

The cells themselves effectively behave as a resistive path to the current flow. Thus the current flow depends on the ratio of the cytoplasm complex impedance to that of the total solution present in the system as revealed in Fig. The insulation property of double layered cell membrane is equivalent to the dielectric material of a capacitor in an electric circuit, whereas the conductive cytoplasm can be considered as a resistor.

The interfacial phenomena form an electrical double layer EDL between an electrode and electrolytic solution, which may also be modelled as a capacitor. Thus combining the mechanisms of an EDL, cell membrane, and cytoplasm, the equivalent electrical circuit presented in Fig. The first part of the circuit shown as R S represents the extracellular solution resistance offered by the conductivity of the bulk solution and a wire connection. The second part of the circuit humman the combined equivalent circuit iis the electrolytic solution and blood cells present in blood.

The solution capacitance, C S represents the dielectric property of water present in the blood. The impedance of the CPE is a measure of the non-faradaic impedance, which arises from the interface capacitance or polarisation of an electrode. The impedance of the CPE is expressed as. From the Table 2it is evident what is the percentage of water in human blood the solution resistance for different designs decreases with the increase of electrode dimensions due to the larger perceentage area allowing more charges to pass away.

Thus the smaller devices show higher impedance than the larger devices as smaller devices have more polarisation impedance and high electrolytic resistance. Thus it can be concluded that the proposed equivalent circuit model of blood has excellent fitting up to a frequency of 1 MHz. It is evident from Fig. Blood serum consists of what is the percentage of water in human blood with proteins, hormones, minerals, and hman dioxide, while plasma consists of serum with fibrin and other clotting factors.

Thus both serum and plasma are rich sources of electrolytes and are subjects to the mechanism of interfacial phenomena that occurs between electrode and electrolytes. When a metal electrode is immersed into an electrolytic solution, an EDL is formed at the interface between metal and electrolyte. According to the model, the EDL consists of two layers, the inner Stern layer and the outer diffuse layer.

The Stern layer has a width of on an atomic magnitude and the ions present in this layer possess ionic bonding between each other. However, the outer diffuse layer is semi-infinite with the ions present in this layer distributed unevenly and is governed by Poisson-Boltzmann theory. But both plasma and serum contain biochemical substances such as protein, enzymes, hormones, liberalised exchange rate management system was introduced in. Therefore, by investigating the mechanism of EDL with respect to biochemical substances along with electrolytes, an equivalent circuit model is proposed in Fig.

The biochemical substances present bloor the serum and plasma covalently couple with electrodes. Thus the double layer capacitance is replaced by a CPE and the electrolytes what is the percentage of water in human blood to behave as a resistor R S. The values of the electric components of the proposed equivalent circuit for plasma and serum are given in Table what is the symbolism of a beetle. It may evident from Table 3 that the bulk resistance for serum and plasma decreases with the increase of dimensions of the working electrodes.

This polarization is dependent on the conductivity and permittivity of the cell interior, membrane, and suspending medium. The electrolytes present in the suspending medium react with the electrodes and form an EDL. Therefore, the double layer capacitance of the electrolytic solution is replaced by a CPE. Thus by combining the effect of EDL, cell membrane and cytoplasm, an equivalent circuit is proposed inset of Fig. This equivalent circuit is similar to the equivalent circuit of blood as described in Fig.

The values of the electric components of the proposed equivalent circuit for RBCs are given in Table 4. It is evident from Table 4 that the values of the solution resistance decrease with the increase of electrode dimensions. The impedances of blood, serum, plasma, and RBCs for different designs are presented in Fig. It indicates clearly that blood shows higher impedance than the others in the low frequency range up to what is the percentage of water in human blood kHz.

Within this frequency range, blood, serum, and plasma impedance values steadily wht with frequency and thereafter the rate of decrease slowes down only for the blood samples whereas for serum and plasma samples the impedance flattens at around 10 5 Hz onwards for all the devices. Thereafter, the impedance value is nearly the same for both the samples.

At lower frequency the electrical current will mainly flow through the electrolyte and rarely percentahe through the cells due to their high impedance.
