ABSTRACT
Certain biopolymers such as DNA can be mixed with hyaluronic acid, to produce
electronic impedance spectra with pseudoinductance loops. Since the loops do not appear in assays of the individual
polymers, including the hyaluronic acid, the process resembles the mutual inductance of twin wire transmission
cable. The polymer inductance loops are studied for reactivity to the field effects of a cellular phone signal.
In addition a synthetic liquid crystal polymer is studied for its morphologic response to the same signal. Both
systems show modulation by telephonic signals.
INTRODUCTION
We have found pseudo inductance (1,2) in aqueous mixtures of DNA and hyaluronic
acid. The two polymers combined in solution regularly show a rounded clockwise loop in the impedance plot (Nyquist),
which they do not show individually (Fig.1). The reversal of phase in the lower portion of the loop resembles the
inductive behavior of a current-carrying wire or coil, manifesting a lag in current. Thus it would appear the two
linear polymers are associated enough in solution to behave electrically as parallel or possibly twisted wires
and so resemble twin wire transmission cable (3). An experiment was designed to introduce a cellular phone signal
to the mixture of paired polymers during the duration of the impedance plot.
In addition, a synthetic liquid crystal polymer composed of palladium, and lipoic acid (PLA) was chosen for the
study. Since PLA shows structural changes as a response to electric or magnetic fields (Freedericks transition),
the micorscopic structural response of PLA to a cellular phone signal was observed.
The two methods explore electronic signaling in aqueous solutions.
