This book is a compilation of collected papers from eminent authors of different institutions in West Bengal. This small attempt has been taken to provide awareness, information and knowledge to the target readers mainly students and young researchers regarding the development of chemical researches towards their contributions in biology and medicine for the benefit of society and human welfare. In this book, efforts have also been given to highlight the researches that are going on in the chemical sciences particularly for the designing of new compounds and devices towards their applications in biotechnology and medicine. I do hope that, this book will greatly enrich the knowledge of researchers, students and readers to equip them with proper implementation.
