A screen-printed microband glucose biosensor system for real-time monitoring of toxicity in cell culture (2011)
Journal Article

#Microband biosensors, screen-printed from a water-based carbon ink containing cobalt phthalocyanine redox mediator and glucose oxidase (GOD) enzyme, were used to monitor glucose levels continuously in buffer and culture medium. Five biosensors were... Read More about A screen-printed microband glucose biosensor system for real-time monitoring of toxicity in cell culture.

Voltammetric behavior of DNA and its derivatives using screen printed carbon electrodes and its possible application in genotoxicity screening (2010)
Journal Article

The aim of the current work was to characterize the electrochemical behavior of DNA and its derivatives using screen printed carbon electrodes (SPCEs). Differential pulse voltammetry (DPV) was carried out on guanine, adenine, 8-oxyguanine, 8-deoxygau...
