Rezumat: In a very recent communication we have shown that the EIS method may be used for classifying the drugs. More precisely it has been shown that to explain the phase difference between the current and the tension it is necessary to use instead of the Warburg pseudo-capacitance CW(ω1), two physically quantities, namely: a pseudo-inductance LW(ω1) and a pseudo-capacitance CW(ω1), which may be arranged in series or in parallel. Consequently, two criteria of classifying the drugs have resulted: for the series arrangement the Thomson radial frequency ωTh,s = [Ls(ω1)Cs(ω1)]-1/2, respective for the parallel arrangement, the Thomson radial frequency ωTh,p = [Lp(ω1)Cp(ω1)]-1/2. As for ω1 it represents the lowest radial frequency used in getting the Nyquist plots (e.g., 1.256 s-1) and has a very important physical meaning: it represents the resonance Thomson radial frequency of both series or parallel circuits, and expresses the highest efficiency that a drug may have, irrespective of the fact that it belongs to the class characterized by the criterion ωTh,s(ω1) or by the criterion ωTh,p(ω1). At the resonance Thomson radial frequency, ω1 the electric energy of the drug, transforms in its magnetic energy and back in its electric energy and this oscillation between electric and magnetic energies occur permanently with a maximum amplitude. This explains why at the resonance radial Thomson frequency ωTh,s = ωTh,p = ω1 the efficiency of drug is maximum. Keywords: multielectrode, Thomson radial frequencies, drugs classification |
