Identifying a crosslink density relationship of acrylamide hydrogels to be used with passive sensors for detecting periprosthetic infection

Identifying the relationship between N, N´-methylenebisacrylamide (mBAAm) and swelling in acrylamide hydrogels will permit their integration with passive sensors. The incorporation of antigen and antibodies within the hydrogels will create an antigen sensitive sensor capable of detecting periprosthetic infection. The relationship between swelling and amount of mBAAm has a nonlinear relationship. Both the swelling and compliance of the hydrogel decrease with increasing amount of mBAAm.
