Resistor-Like Porous Silicon Glucose Sensor with Silver Nanoparticles
In the paper, the possibility of enzymatic glucose detection by porous silicon with silver nanoparticles is
investigated. Porous silicon was prepared by metal-assisted chemical etching with silver chemical deposition. It is shown
that obtained resistor-like structures are sensitive to hydrogen peroxide and thereby can detect glucose via glucose oxidase
reaction with sensitivity up to 0.4 mA/V∙%. Sample preparation conditions greatly influence sensor performance due to
different surface area and surface states density.
