UK chemical measurement and biodetection expert Stratophase has recently launched technology based on principles which measure changes in the refractive index of liquids. Capable of detecting even the most minute changes in the chemical composition of liquids SpectroSens offers chemical manufacturers a cost effective inline option for multipoint concentration tracking.
At the core of the system is an optical silicon chip which, by measuring refractive index, accurately analyses changes in any liquid on the surface of the chip. When fuctionalised it can also directly measure the binding of antigens to antibodies attached to the chip surface. Perfectly suited to use in laboratories and for point testing in a production environment, multiple sensors can also be optically networked over large areas to a single readout unit, offering economical multipoint measurements.
Using optical signals means that the SpectroSens devices do not need electrical power, and are therefore intrinsically safe for use in flammable environments, making the technology a cost-effective option for use in hazardous areas, or with combustible chemicals. The optical technology also means that the sensor systems are unaffected by electromagnetic interference.
The ability to make multiwavelength measurements at a single point offers the potential for compositional “fingerprinting” of liquids, further increasing the depth of information available to the user. The SpectroSens chip’s real-time data gathering capability enable simultaneous measurement of reaction kinetics for multiple biochemical targets or multipoint inline measurements for continuous process monitoring.
Stratophase has developed the SpectroSens technology based on proven science from telecoms, optics and biotech. The sensor chips are customisable for specific applications and Stratophase is currently working with customers to develop bespoke and cost effective systems to suit industry specific highly specialized requirements. The technology also has applications in counter bioterrorism, pharmaceutical manufacturing and food and drink manufacturing.
Over the last year the technology has secured Stratophase in excess of $2 million in contracts and international private investment. Multiple collaborative projects endorse the optical sensor technology’s sound scientific basis and commercial applications.
