Capacitive sensors for the characterization of proteins and amino acid adsorption

Biocompatibility of biomaterials depends on protein adsorption processes. The comprehension and control of the interaction between proteins and solid surfaces therefore finds important applications in various biomedical fields. A capacitive sensor is presented for the characterization of the adsorption kinetic of proteins such as human serum albumin and cysteina. A large amount of experimental data have been gathered in order to validate the measurement approach proposed.
