A novel Ag nanoparticles/TiO2 nanowires-based photodetector and glucose concentration detection

Semiconductor photoelectroanalysis and photobioelectroanalysis: A perspective

“…A photoanode architecture based on graphene laser-deposited onto tin-doped indium oxide was employed in conjunction with a nickel catalyst and CdS quantum dots for the photoelectroanalytical detection of glucose [24]. Titania nanomaterials were combined with silver nanoparticles [25] to give glucose photoelectrochemical sensors. But also pure TiO2 9 nanotube structures have been employed for photoelectrochemical glucose detection [ 26 ].…”

Preparation and Photovoltaic Performance of a Composite TiO2 Nanotube Array/Polyaniline UV Photodetector

“…TiO 2 is one of today's most popular wide-bandwidth semiconductors due to its benefits of a strong chemical stability, low toxicity, and environmental friendliness [21][22][23]. Rutile TiO 2 and anatase TiO 2 have bandwidths of around 3.0 and 3.2 eV, respectively [24]. The heterojunction formed by combining the two crystal phases can reduce the forbidden bandwidth and produce a mixed crystal effect [25], which can somewhat facilitate the separation of photogenerated electron-hole pairs.…”

Fabrication and Characterization of Zinc Oxide Nanowire Based Two‐electrode Capacitive Biosensors on Flexible Substrates for Estimating Glucose Content in a Sample

“…These devices, however, suffer from poor enzyme immobilization on the solid electrode. To meet such challenge, researchers around the globe are utilizing nanomaterials of different structures and zinc oxide (ZnO) nanowires have emerged to be the promising candidates for glucose sensing [23][24][25][26][27]. ZnO is an excellent non-toxic nano-material with high isoelectric point to allow easy immobilization of enzyme (with a low isoelectric point) due to electrostatic interaction.Also, the high chemical stability of ZnO and its ability to fast electron transfer are useful to develop enzyme based sensors by immobilizing appropriate bio-molecules without the mediation of electrons [26][27].…”
