M. Schwartz et al., ELECTRICAL-PROPERTIES OF GLUCOSE-SENSITIVE HYDROGELS - SWELLING AND CONDUCTIVITY RELATIONSHIPS, Journal of biomedical materials research, 41(1), 1998, pp. 65-70
The electrical characteristics of a glucose-sensitive polymeric hydrog
el have been studied. The hydrogel matrices were prepared by radical p
olymerization of solutions containing 2-hydroxyethyl methacrylate, N,N
-dimethyl aminoethyl methacrylate, tetraethylene glycol dimethacrylate
, ethylene glycol, water, and glucose oxidase. The hydrogels displayed
faster and higher swelling rates for lower levels of a crosslinking a
gent. Electrical conductivity was found to be a sensitive measurement
of the state of the swelling. A simple model that relates hydrogel swe
lling and conductivity has been proposed. (C) 1998 John Wiley & Sons,
