Two-Photon Research

Two-Photon Research is a Canadian deep-technology company developing aptamer-based discovery tools and photonic diagnostic devices. Its healthcare-related activities center on computational synthesis and validation of aptamers and high-sensitivity in vitro diagnostic systems for biomarker detection and monitoring. The company markets AptaSoft for aptamer design and describes CAST as a bio-photonic diagnostics platform with femtomolar sensitivity, including use cases in pathogen detection such as SARS-CoV-2. Beyond health applications, the company also works in photonics, GaN and GeSn devices, microelectronics, and direct-write lithography. Overall, it appears to be a platform-oriented private company operating at the intersection of molecular diagnostics, photonics, and microfabrication.
