Principle of biosensor based on thin film degradationDisposable biosensors for the detection of enzyme activities based on the enzymatic degradation of thin polymer films have been developed. Film degradation in the presence of an enzyme is monitored using impedance or Quartz Crystal Microbalance.

Degradation of poly(ester amide) at different ?-chymotrypsin concentrations: The rate of degradation depends on the enzyme concentration.
