FIG. 1.

A block diagram of the SQUID-based nonlinear dielectric spectrometer used in the present work. The bottom inset shows the two pin probe used to apply the sinusoidal electrical field (0–5 V, 1–300 Hz) to 10 ml of cell suspension and the reference solution.

FIG. 2.

Variation of the third harmonic with the source frequency measured during the nonlinear dielectric spectroscopy of yeast with constant electrical field . Data were normalized to the fundamental to remove position dependence.

FIG. 3.

Variation of the third harmonic with the excitation electrical field measured during the nonlinear dielectric spectroscopy of yeast with constant excitation frequency (13 Hz). Data were normalized to the fundamental to remove sensor position dependencies.

FIG. 4.

Procedure for measuring the harmonics generated by the yeast cells. (a) Measured harmonics generated by the reference medium. The SQUID output voltage is proportional to the external magnetic field with . (b) Measured harmonics generated by the yeast cells. (c) Normalized magnitude of harmonics generated by the cell suspension after reference subtraction.

FIG. 5.

Comparison of harmonics generated by the reference medium having the same conductivity as the yeast suspension measured using our SQUID-based setup (right) and the conventional four probe (left). Each data set was normalized to the fundamental for comparison.

FIG. 6.

Comparison of the harmonics generated only by the yeast cells using the SQUID-based setup (left) and the conventional four-probe (right). Data were normalized to the fundamental for comparison.
