ABSTRACT
The dream of every cell is to become two cells. Francois Jacob (Nobel laureate Prize for Physiology or Medicine, 1965)*
The United Nations Educational, Scientific and Cultural Organization announced that 2015 was the International Year of Light, highlighting the enormous achievements of light science and its applications. It is no surprise that there are several biophysical tools developed that use light directly to facilitate detection, sensing, and imaging of biological material. Many of these go far beyond the basic methods of light microscopy and optical spectroscopy we discussed in Chapter 3.
