Acrylic copolymer membranes for biosensors (ACRYLIC COPOLYMER MEM-BRANES FOR BIOSENSORS)

摘要

Discloses a homogeneous membrane 20 made of an acrylic copolymer and capable of absorbing water at 10% to 50% by weight of the dry weight of the membrane. The copolymer comprises a hydrophilic component comprising an acrylic ester having a poly (ethylene oxide) substituent as part of the alcohol moiety. The membrane 20 is useful for manufacturing a biosensor, for example, a glucose sensor 10 to be used in vivo. It is possible to prepare membranes having various permeabilities by changing the ratio of the monomeric compound.
