At a Glance
Low-cost, single-use disposable sensor with multiple sensing channels, each sensitized to detect different chemical or biological substances.
Technical Background
At Fraunhofer HHI, a photonic sensor technology has been developed that allows simultaneous, highly sensitive real-time measurements of chemical or biological parameters.
Substance concentrations can be determined without markers in liquid or gaseous analytes, thanks to the functionalization of the sensor surface. Microring sensors can be combined on a sensor chip for use in multi-parameter analytics in Point-of-Care testing.
- Measurement of refractive index via shift of optical resonances
- Cascading of sensor elements
