i-GEST Co., Ltd. provides various silicon-based biosensor platforms for diagnoses and environmental pollution. The advanced platform consists of disposable strips and a portable reader system. The strip contains Si-nanostructure transistors with different dimensions that generally operate in a liquid environment with a low detection limit and high sensitivities. This disruptive technology will expand to in-vitro diagnostic markets, including immunoassay, point-of-care testing, and molecular diagnostics.
