Abstract

Homogeneous membranes (20) are disclosed which are composed of acrylic copolymers and are capable of absorbing % to 50 % of their dry weight of water. The copolymers include a hydrophilic component which comprises acrylic esters having a poly(ethylene oxide) substituent as part of the alcohol moiety. The copolymers further comprise methacrylate and/or acrylate monomer units. The membranes (20) are useful in the fabrication of biosensors, e.g., a glucose sensor (10) intended for in vivo use. Variations in the ratios of the monomeric components make possible the fabrication of membranes which have varying permeabilities.
