Conducting polymer-based biosensors
TLDR
In this article, a generic biosensor concept is proposed, which involves immobilization of an appropriate enzyme in the conducting polymer matrix, which results in a change in redox potential and/or pH of the micro environment in the polymer matrix.About:

The estimation of pepsin, trypsin, papain, and cathepsin with hemoglobin.
TL;DR: It is considered simpler and more useful to describe completely the procedures as they are now used in this laboratory, and to avoid confusion about results already published no radical changes have been made.
