Abstract

Recently, for sensor application, porous silicon has received a great deal of attention due to the height specific surface area and the easy fabrication using some established processes of the usual silicon technology. We herein, report the functionalization of porous silicon using an alkylsilane coupling agent (3-aminopropyl triethoxysilane-APTS) for biomedical applications. The molecular structure was characterized with Fourier-transform infrared (FTIR) technique and the morphology of the substrates was studied with optical microscopy with fluorescence module. Porous silicon with fluorescent agent on its surface was analysed by UC4 microarray scanner from genomic solutions.
