Abstract
(EN) The invention belongs to the technical field of biological detection, and discloses an optical biosensor and a COVID-19 virus detection device. The optical biosensor provided by the invention comprises a monocrystalline silicon substrate and a nano-porous silicon film optical device arranged on the monocrystalline silicon substrate, and the nano-porous silicon film optical device comprises a porous silicon single-layer interference film, a porous silicon Bragg reflector or a porous silicon micro resonant cavity; a composite metal film is deposited on the surface of the nano-porous silicon filmoptical device, and a biological probe is coated on the surface of the nano-porous silicon film optical device in sequence. By designing the structure of the nano-porous silicon film optical device and depositing the composite metal film on the surface of the nano-porous silicon film optical device, the detection sensitivity of the optical biosensor is remarkably improved, and the optical biosensor is suitable for detecting COVID-19 viruses and other pathogens.
