The University of Southampton has made a biosensor which can detect water pollutants in the range 1ng/l to 1µg/l. It is based around a sodium-doped glass slide with 3×3µm potassium-doped waveguides in its surface. “The potassium gives it a higher refractive index, so these waveguides work like optical fibres,” Professor James Wilkinson of the Optoelectronics Research Centre told Electronics Weekly. ...

Technology for inkjet printing lines of conductive inks and polymer semiconductors just 10µm wide is the target of a project being led by Cambridge firm Plastic Logic. The company, with the University of Cambridge and materials suppliers Avecia and Gwent Electronic Materials, was last week awarded £1.2m as part of the Government’s £90m Micro and Nanotechnology Manufacturing initiative, announced last ...
