Download scientific diagram | Electrochemical impedance spectroscopy (EIS) of POPC bilayer resistance (A) and capacitance response (B) to bilayer only (control), 0.05 vol% Triton (detergent),...

Jul 8, 2021 · EIS was used to analyze the effect of PS nanoplastics with and without the presence of soft/hard protein coronae. The EIS spectra were described by an electrical equivalent circuit (EEC) model, shown in Fig. 8(d).

Oct 30, 2021 · Fast Fourier transform electrochemical impedance spectroscopy (FFT-EIS) is applied to probe the effect of simple carbohydrates on the impedance characteristics of POPC bilayer lipid membranes. Montal–Mueller technique for planar lipid bilayers yields stable bilayer membranes for assessment of their impedance properties to be probed here by an ...

Jul 5, 2022 · The electrical properties of the lipid bilayer were characterized using EIS, an alternating current technique that is commonly used to measure the frequency-dependent complex impedance of electrochemical systems.

Specific capacitance and resistance of POPC membranes in aqueous solutions containing 1 mmol/L NaCl and 200 mmol/L glucose, fructose or sucrose; data obtained from FFT-EIS of BLMs by...

Jan 7, 2025 · Here, we combine electrical impedance spectroscopy (EIS) experiments with molecular dynamics (MD) simulations to study the effect of the steroids cortisone, prednisolone and progesterone and the steroid-like compounds enoxolone and carbenoxolone on the ion permeability and structure of phospholipid bilayers composed of the zwitterionic lipid POPC.

In this study, we have shown the model of a microscale dielectric membrane capacitor including POPC structures. We have shown that Quantum effect has appeared in a small free space of the membrane thickness due to number of phospholipids layers.

Combined, surface plasmon resonance (SPR)/electrical impedance spectroscopy (EIS) measurements (Fig. 3) were conducted by injecting the peptide in small increments while simultaneously observing (1) the kinetics associated with the peptides binding to the bilayer (SPR) and (2) the formation of peptide-lined defects that increase membrane ...

Sep 20, 2022 · The results from tBLM/EIS experiments showed that Ca 2+ significantly reduces the capacity of CAME and CAF to disrupt POPC bilayers. As phenolic acids are known metal chelators, we needed to exclude the possibility that Ca 2+ interferes with membrane disruption by binding to the phenolic compound in solution and subsequently preventing the ...

Jul 16, 2021 · In this study, we demonstrate the use of tethered lipid bilayer (tBLM) electrical impedance spectroscopy (EIS) combined with MD simulations to study SMMIs. tBLM/EIS is a technique to monitor the ion permeability of phospholipid bilayers in real-time.
