Enhanced enzyme activity in silicon integrated enzyme reactors utilizing porous silicon as the coupling matrix

Vapor-phase silanization of oxidized porous silicon for stabilizing composition and photoluminescence

“…8 The porous structure and a relatively large surface area have also made the silicon an ideal matrix for immobilization of a variety of biomolecules including enzymes, 9 DNA fragments, 10 and antibodies. 11 The electronic or optical properties of porous silicon can also be used as the transducer of biomolecular interactions, thus qualifying its utility in biosensor applications. 12,13 The devices fabricated with PSi have shown promise, owing to the ease of fabricating one-dimensional photonic crystals.…”

Biosensors Based on the Photoluminescence of Porous Silicon. Overall Characteristics and Application

“…Одним из простейших вариа-нтов является использование развитой повер-хности ПК в реакторах для иммобилизации ферментов [47]. Именно развитость и значите-льная химическая реактивность поверхности ПК используется при создании ионных биосе-нсоров.…”

Label-Free Electrochemical Detection of Tetracycline by an Aptamer Nano-Biosensor

“…Nano-porous silicon (PS) is an interesting material with a diversity of applications, which has recently become available for biosensing (King et al, 2007;Cunin et al, 2002;Drott et al, 1997;Laurell et al, 1996;Orosco et al, 2006;Setzu et al, 2007;Zhang et al, 2009). The advantages of the PS result from several unique features: intrinsically high surface-to-volume ratio, biocompatibility and relatively simple incorporation into biosensors.…”
