Over the last 10-years or so there have been major developments in imaging technology e.g. it now possible to view components in living cells at high resolution. These developments have arisen through advances in technology, sensors in particular, staining techniques and off course software. 

One of the companies that has been responsible for some of these developments is Andor Technology, Andor is now part of Oxford Instruments. Andor have recently provided a series of articles on developments in imaging technology. See below. The science content of these articles is high and they are ideal for undergraduate and postgraduate teaching.
