Hybridization assay of insect antifreezing protein gene by novel multilayered porous silicon nucleic acid biosensor

Enhancement of QDs' fluorescence based on porous silicon Bragg mirror

“…In recent years, researchers have combined waveguide or photonic crystals with QDs, and fabricated devices with excellent properties [8][9][10][11]. Porous silicon (PSi) is a material with good biocompatibility, in addition, large internal surface areas, capability for size-selective filtering, ease of face functionalization, and can fabricate various types photonic devices are characters it has [12][13][14], these advantages have made PSi attract great interests in biosensing [15][16][17]. Combining QDs with PSi and utilizing the photonic structure of PSi can fabricate biosensors with high sensitivity and excellent performance [18,19].…”

Photonic Crystal Sensors Based on Porous Silicon

“…Another type of photonic structures so-called polybasic multilayers were suggested for the fabrication of highly sensitive porous silicon biosensors. Lv et al , demonstrated their application to the detection of antigen-antibody interactions and DNA hybridization [70,71]. …”

Study on the Formation of Au Nanoparticles on Fresh and Oxided Porous Silicon Microcavity Substrate

“…For biochips based on integrated optical devices, the fresh etched PS is unstable in the air owing to the "fragile" Si-H bond easily to be oxidized. In order to get stable optical properties [14][15][16], we researched on two different ways. One is the direct deposition of AuNPs on oxided PSM substrate, and the other is the oxidation on the fresh PSM substrate after AuNPs being deposited.…”
