Smallest High Resolution Microscope
Researchers at University of Barcelona, Technical University of Braunschweig (Germany) and University Rome Tor Vergata (Italy) have devised the smallest and cheapest ever high resolution microscope using nanoLEDs that act as lightening source under the European ChipScope project. Instead of lenses the size of nanoLEDs determine the resolution of the microscope. The device uses 200nm nanoLEDs. It allows the observation of some viruses and cellular processes in real time without the problems of current high-resolution techniques. The new technology is dependent on the size of the lightening source instead of the detection system. That is, instead of an only source of light –such as in conventional microscopes–, these used millions of light sources in miniature The new microscope has been tested with different samples among which are cellular images of idiopathic pulmonary fibrosis (IPF), a chronic lung pathology related to age which affects humans and causes half a million deaths per year.
