When Xander Sim, the inventor of Quiz biochip-based PCR, co-founded Cell ID in 2014, he had one goal in mind – to combine engineering and biological sciences to deliver fast, accurate, affordable and mass-deployable diagnostic solutions for home and near-patient use.

As the medtech firm’s Chief Technology Officer (CTO), Sim oversaw the R&D for several products. This included Cell ID’s flagship biochip-based PCR test kit for HIV viral load, malaria parasitaemia, nucleic acid test (NAT) for COVID-19 extracted ribonucleic acid (RNA) and one-step (OS) COVID-19 saliva tests.
