Renishaw Diagnostics Limited (RDL) played a key role in an EU project team that recently announced the successful development of a new technology with significant implications for the future of photonic sensor applications.
A nine-member consortium led by the VTT Technical Research Centre of Finland successfully developed mass-producible, polymer-based nanophotonic sensors that could be used in applications ranging from air contaminant identification to the detection of melamine in milk products.
RDL is the supplier of Klarite, the world's leading commercially available surface enhanced Raman scattering (SERS) substrate used for the measurement of trace materials in a range of chemical and biological applications. Based on photonic sensor technology, Klarite substrates are currently manufactured by photolithographic etching of a silicon substrate. The development of a polymer based substrate manufactured using nano-imprinting, offers the possibility of roll-to-roll substrate manufacture with the potential to reduce manufacturing time and cost significantly for high volume applications.
Dr David Eustace, Commercial Business Manager at RDL explains that the PHOTOSENS project has developed a novel and highly cost effective manufacturing method for periodic nanostructures, which form the basis of most SERS substrates.
RDL looks forward to further developments in this field to open up a new range of applications for this highly sensitive and selective analytical technique.
