Abstract
A composition for blood glucose measurement includes a copolymer including three types of monomers having a hydrophobic group, a hydrophilic group, and a boronic acid moiety, and a conductive material mixed with the copolymer, thereby enabling volume changes in response to glucose to be converted into electrical signals. An electrochemical sensor for blood glucose measurement includes a working electrode that includes the composition.
