Our Business
The mission of Diagnostic Biosensors is to produce miniaturized biosensors and actuators that integrate with diagnostic sensing systems for life science and analytical applications. These micro-components are small and inexpensive enough to be thrown away along with a larger consumable cartridge or tube.  The company has a
leading position in combining silicon sensors and actuators with molded plastic sample handling assemblies.
