Nanoporous Silicon Materials for Bioapplications by Electrochemical Approach

Abstract

Nanoporous materials have attracted extremely intense scientific attention since the photoluminescence discovery at room temperature because of the quantum confinement effects. It is well known that in addition to the superior photoluminescence, nanoporous silicon materials prepared by the electrochemical method are promising materials for applications in catalysis, chemical, energy storage and biological sensing, due to its high porosity, modifiable surface, biocompatibility and biodegradability, which comprise tunable optical porous Si structure and the applications such as biosensing, in vivo imaging and gas sensing. As a result, the straightforward electrochemical methods used to create nanoporous materials are notable, particularly for nanoporous silicon materials that aim to provide crucial information about the appropriate techniques to take into account the environmentally friendly developments for the future reduction of environmental risks.
