Stratophase has introduced the Spectrosens sensor chips, which monitor the relative chemical compositions of liquids.
When the sensors are functionalised, they can detect all classes of biological targets, including proteins, viruses and bacteria.
Spectrosens technology is based on principles that measure changes in the refractive index of liquids.
At the core of the system is an optical silicon chip that, by measuring refractive index, accurately analyses changes in any liquid on the surface of the chip.
It also directly measures the binding of antigens to antibodies attached to the chip surface.
The result is a device that can be used for laboratory analysis or for chemical monitoring and bio-detection.
The Stratophase sensors feature precision better than one part per million.
They are suitable for use in any liquid-processing application.
The Spectrosens chip's real-time data-gathering capability enables simultaneous measurement of reaction kinetics for multiple biochemical targets or multipoint inline measurements for continuous process monitoring.
The ability to make multi-wavelength measurements at a single point offers the potential to compositionally 'fingerprint' liquids, further increasing the depth of information available to the user.
It also offers the potential to determine the relative size of biological entities, increasing the specificity for a given assay.
The Spectrosens sensor chips are customisable for specific applications.
The technology has applications in counter bioterrorism, industrial processes, pharmaceutical manufacturing and food and drink manufacturing.
