Fluorescence filters are part of a process that allows computers to be built using sugar, and not silicon. Sugar and the building blocks of computing Scientists at the Friedrich Schiller University Jena in Germany have demonstrated how simple logic gates – the building blocks of computing – can be built using sugar. The key to […]
Optical filters near infrared could be used to create cancer-detecting goggles, allowing surgeons to spot tumours in real time, according to research from the US. Optical filters to detect cancer cells early A study in the Optical Society’s academic journal Optics Letters outlines the process, which combines optical filters near infrared for the detection of […]
