Affinité portable device qSPR is the world's first surface plasmon resonance (SPR) biosensor that uses a disposable cartridge for sample analysis. Compared to the large and complex SPR instrument in the market today, Affinité’s unique portable SPR design not only brings simplicity and accessibility to bio-molecular testing, but the cartridge design also gives clinicians access the power of SPR in BSL labs while minimizing risks of cross contaminations and exposure. For many researchers, having Affinité’s portable SPR represents the only accessible SPR, especially during COVID-19 lockdowns, to quickly continue developing immunoassays for cancer, rapid tests for infectious diseases, as well as doing population immunity studies. One of the main values of Affinité’s portable SPR comes from its simplicity as an on-the-bench, in-process screening that can be used as a point-of-care (PoC) diagnostic tool. By transforming the traditional reliable SPR into an accessible and simple biosensing tool, Affinité is developing medical diagnostics platform to improve success outcomes and cost of therapeutic drug monitoring (TDM) and gene therapy. 

Established in 2015 by Professor Masson and Professor Pelletier from the Université de Montréal, Affinité instruments’ foundation is built on a deep knowledge accrued on over a decade of research in SPR. The commercialization of this unique SPR innovation is spearheaded by a diverse leadership experienced in business, science and engineering. Affinité Instruments has proven use of its proprietary portable SPR technology in the areas of rapid testing through recent partnership with Canadian Universities for CHIR Canadian 2019 Novel Coronavirus (COVID-19) Rapid Research, as well as collaborations with project partners in Covid-19 PoC challenge under Innovative Solutions Canada. Affinité Instruments is part of the prestigious 2021 Canadian Technology Accelerator (CTA) Boston cohort to promote SPR as a PoC platform to simplify life science testing and diagnostics.
