Sentence examples for bilayer capacitance from inspiring English sources

Membrane quality was assessed by measuring bilayer capacitance and conductance.

In agreement with these data, the presence of cholesterol in reconstituted planar lipid bilayers triggered the stable insertion of anandamide detected as an increase in bilayer capacitance.

In response to anandamide, there was a transient increase in the bilayer capacitance during the first minute (not shown), followed after 5 minutes by a stable capacitance decrease of 15±8% (p<0.05; range: 14 2 µF/cm2, n = 7, Figure 8A).

To discard the difficulty of tau (time constant) evaluation online, the planar lipid bilayer capacitance was calculated from the modified equation: Cm = t/Rpln(I0/It) [18] where t = time in seconds, I0 is the steady state current at t = 0, It is the current at time t, and Rp is the leakage resistance given by Rp = RmRi/Rm+Ri for potentials from 30 60 mV.

Typical bilayer capacitance values were between 250 and 350 pF.

Taken collectively, by measuring the electrical current directly through SLBs, as well as the sensitivity of the Dirac point to changes in the electrolyte pH and concentration before and after deposition of SLBs, in addition to the bilayer capacitance and fluorescence, we provide strong evidence that the graphene is insulated from the electrolyte environment by SLBs.

Bilayer capacitances were in the range of 50 75 pF.

We model the system as two capacitors in series: The first is the well-known lipid bilayer membrane capacitance Cmembrane (from prior studies as well as our own measurements described in the Supporting Information 3 to be ∼0.6 μF/cm).

The integrity of the fully sealed suspended lipid bilayer, as determined by capacitance and electrical recording, remained stable while engaging the AFM.

If the conductance of the bilayer remains low, the capacitance of the system could be directly obtained from the rms value of the squared output (I = CAdV/dt), capacitance being equal to V/K, with K =10 mVApF-1 The system was calibrated with capacitors of known values and the contribution of the line (cables, connections... outside the bilayer) was substracted.

DMPS bilayers have relatively large capacitance when compared with those formed from similar molecules and this is attributed to a high solvent content within the bilayer, resulting from the need for solvation of the negatively charged lipid headgroups.
