At the end of the 2D experiment, we will have acquired a set of N FIDs composed of quadrature data points, with N /2 points from channel A and points from channel B, acquired with sequential (alternate) sampling. How the data are processed is critical for a successful outcome. The data processing involves (a) dc (direct current) correction (performed automatically by the instrument software), (b) apodization (window multiplication) of the <2 time-domain data, (c) Fourier transformation and phase correction, (d) window multiplication of the t domain data and phase correction (unless it is a magnitude or a power-mode spectrum, in which case phase correction is not required), (e) complex Fourier transformation in Fu (f) coaddition of real and imaginary data (if phase-sensitive representation is required) to give a magnitude (M) or a power-mode (P) spectrum. Additional steps may be tilting, symmetrization, and calculation of projections. A schematic representation of the steps involved is presented in Fig. 3.5.

FIGURE 7.2 Schematic of a DNA sensor based on a capacitive EIS structure. For operation, a DC (direct current) polarization voltage (VG) is applied via the reference electrode (RE) to set the working point of the EIS sensor, and a small AC (alternating current) voltage (E ) is applied to the system in order to measure the capacitance of the sensor. ssDNA - single-stranded DNA, cDNA - complementary DNA, dsDNA - double-stranded DNA.

An electrolytic cell is similar to a voltaic cell, but there are some slight differences. One of the first differences is the source of electrons. In the voltaic cell, the source of the electrons is the spontaneous oxidation that occurs at the anode. Because no spontaneous reactions occur in an electrolytic cell, the source of electrons is a DC (direct current) power supply. The power supply forces electrons to the cathode rather than the potential of the half-reactions. The cathode in an electrolytic cell acquires a negative charge (which is opposite from a voltaic cell) because electrons are being forced onto it, while the anode takes on a positive charge (which is opposite from a voltaic cell) because electrons are being removed from it by the power supply.
