Magnotech

Magnotech is a type of biosensor using magnetic nanoparticles to measure target molecules in blood and saliva in a matter of minutes.

The man behind the invention of Magnotech is Philips Research Fellow, Professor Menno Prins. The aim is to expand the rapid diagnosis sector of the in vitro diagnostics market.

Integrated into a disposable biosensor is a cartridge that inserts into a hand-held analyzer. It automatically fills itself from a single drop of blood or saliva. Once filled, no other fluid movement is required. The entire assay process within the cartridge is executed by controlled movement of the magnetic nanoparticles within the cartridge using external magnetic fields.

The cartridge, constructed entirely from plastic components, has no moving parts or embedded electronics, and is disposable. The analyzer unit contains the electromagnets, optical detection system, control electronics, software and the read-out display.

Proof of concept tests already show that the cardiac marker Troponin I can be measured in plasma in around five minutes.
