High-sensitivity stimulated emission microscopy
Colourful, non-fluorescent tiny molecules, such as haemoglobin, can now be imaged with high resolution and sensitivity thanks to a new microscopy technique revealed in Nature (9/09. pp 1105-1109; N&V). The technique promises to find broad applications in medical imaging and biological research, according to researchers Xiaoliang Sunney Xie (Harvard University, Cambridge, Maryland) and Stefan…
