UK biochemical measurement and detection
experts Stratophase demonstrate optical technology for real-time determination
of reaction kinetics at Pittcon
* Capable of detecting even the most minute changes in the chemical composition
of liquids
* Robust, self-referenced sensor chips suitable for use in any liquid processing
application
* Customizable optical chip detects all classes of biological targets
Pittcon booth 837: UK sensor company Stratophase has launched
a new technology based on principles which measure changes in the refractive
index (*RI) of liquids. In native form, the sensors monitor the relative
chemical compositions of liquids, when functionalized the sensors are capable
of detecting all classes of biological targets, including proteins, viruses
and bacteria.
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. It also directly measures the binding of antigens to antibodies
attached to the chip surface. The result is a small, versatile and accurate
device which can be used for laboratory analysis or in the field for chemical
monitoring and bio-detection.
With precision better than one part per million, the Stratophase sensors
are capable of detecting even the most minute changes in the chemical composition
of liquids. The robust, self-referenced sensor chips are suitable for use
in any liquid processing application. 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.
The ability to make multiwavelength 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, further increasing
the specificity for a given assay.
Stratophase has developed the SpectroSens technology based on proven science
from telecoms, optics and biotech. The sensor chips are customizable 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, industrial processes, 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.
