Using light-emitting proteins in two different ways let researchers peer within living cells STED microscopy can painstakingly create a high resolution image by scanning a sample in nanometre-wide strips.Click here to enlarge Johan Jarnestad/The Royal Swedish Academy of Sciences The2014 chemistry Nobel prizehas been given to three pioneers of biomedical imaging, whose work has enabled nanoscale features within cells to be captured in exquisite detail.Eric Betzigof Howard Hughes Medical Institute, US,Stefan Hellof the Max Planck Institute for Biophysical Chemistry, Germany, andWE Moernerof Stanford University, US, will share the prize for the development of super-resolved fluorescence microscopy. The techniques they developed enabled extremely high resolution images to be produced using optical microscopy. Their work circumvented the problem of the diffraction limit the inability of light microscopy to distinguish between structures smaller than half the wavelength of visible light or about 200nm. This advance allowed nanoscale structures including individual molecules to be visualised within cells while they are still alive, something that isnt possible with techniques such as electron microscopy. Most of the processes in chemistry and biochemistry take place at length scales that are much smaller [than the wavelength of light], saidSven Lidin, of the chemistry Nobel prize committee, speaking at … Continue reading →
