BIOSENSORS BASED ON NANO ELECTRODE ENSEMBLE AND SCREEN PRINTED SUBSTRATES

摘要

Metal nanowires were synthesized according to an electroless deposition method in polycarbonate template, obtaining nano electrodes ensembles with specific features and well defined diameter size. Nano electrode ensembles were coupled with disposable screen printed substrate in order to increase the sensitivity of the commonly used carbon graphite working electrode for electrochemical sensing. Furthermore, working surface modification provided the basis for original protein immobilization procedures that otherwise would not be allowed.
