Functionalization of nanostructured porous silicon microcavities for glucose oxidase detection

Silicon Nanocrystals in Porous Silicon and Applications

“…Similar concept was reported by Guillermain et al [201]. Glucose oxidase detection with a resolution of 25 nM has been demonstrated using stabilized and functionalized PSi microcavities [202].…”

Progress of porous silicon APTES-functionalization by FTIR investigations

“…Silanization of Si wafers and PS layers with organosilanes requires a pre-oxidation step [15][16][17], generally thermal oxidation. The latter affects the structure of PS causing a destruction of the hydrogen-terminated bonds, which are responsible of the high reactivity towards other chemical and biological species leading to an enhanced sensibility for the confinement of organic molecules [18]. In this work, we studied functionalization of Si and PS samples by organic molecules via dipping in hydrolyzed APTES solution for various times.…”

Surface-Functionalized Porous Silicon Wafers: Synthesis and Applications

“…The tunable porosity of porous silicon (p-Si) and concomitant physical properties such as photoluminescence and electrical conductivity have long been exploited for solar (Menna, 1995;Vitanov, 1997), biomedical (Low, 2009;MacInnes, 2009;Alvarez, 2009), and (bio)sensing (Razi, 2008;Palestino, 2008;Janshoff, 1998) applications. The most common method used to fabricate porous silicon is electrochemical etching (anodization) of a doped Si wafer in an aqueous/ethanolic HF electrolytic solution (Fahlman, 2011).…”
