Synopsis Present era is the era of Molecular Biology, Biotechnology, nanotechnology and targeted medicines, so the students are required to keep themselves abreast with the latest techniques, principles and methodology involved in the aforesaid areas of life sciences. Since most of the techniques are based on the principles of Biophysics, it becomes difficult for biology students to grasp them the way they should be. Therefore, an effort has been made by the authors to present a simple and concise account of the principle4s, instruments, methodology and specificities of the experimental techniques. Much emphasis has been laid on most commonly used techniques and instruments such as Microscopy, Photomicrography, Spectroscopy, Chromatography, Electrophoresis and Histological techniques, etc. A detailed description of the subject-matter is presented covering the theoretical as well as practical aspect. Authors are sure that this book will certainly prove its worth for U.G. and P.G. students of basic and Life science.
