Archer’s biochip is the core of a new generation of digital sensing devices - starting in human health and extendable to agriculture and industry. By combining accuracy, speed, and low cost, the platform targets surging global demand for diagnostics that empower patients, improve outcomes, and ease pressure on healthcare systems.
Our ion-sensing biochip marks an inflection point in diagnostics. Unlike lateral flow tests that have changed little since the 1980s, Archer’s platform enables digital, highly accurate measurements previously out of reach. Integrated into disposable cartridges, it can analyse a finger-prick of blood in minutes, delivering the precision required for many health applications.
The first application is rapid, low-cost, and accurate measurement of potassium (K+) in blood - a critical need for people living with chronic kidney disease (CKD). Today, potassium monitoring is slow, costly, and clinic-based. Archer’s biochip is designed to enable frequent testing at home or at the point-of-care, helping patients and clinicians act quickly, reduce risk, and improve quality of life.
A core part of the Biochip is its biosensor, known as the graphene field effect transistor (gFET). Archer has already created several generations of the gFET with multiple foundry partners to further derisk the technology. By having a miniaturised ‘lab-on-a-chip’, Archer aims to provide better access to healthcare across the globe and improved patient outcomes through enhanced diagnostics.
Built-in connectivity unlocks learning from large health datasets enhancing patient care and enabling new insights. From this foundation, the platform can extend to a wide range of ion-sensing applications across human health, while opening opportunities in agriculture and industrial monitoring. By replacing outdated methods with a scalable, digital biochip, Archer aims to transform how conditions are monitored and managed worldwide - a compelling opportunity for investors in next-generation diagnostics.
