This book gives insight into the natural primary metobolites and secondary metabolites fecilitate the metalic solution to a nano particle conversion. This newer technique gives chance of preparation of variety of nanoparticles for different activities especially anti bacterial, anti cancer and anti fungal. The method of silver, copper, gold nanoparticles are very easily prepared by bioreduction method.

A variety of different plants have been reviewed. Based on brief review, the compounds have been isolated for assessment of their pharmacological activities, and it¿s believed that these compounds found to be the most active for their further studies. The objective of these findings is to systematically estimate and evaluate the outcome of various plant metabolites and collate these findings to be used as a guide for future biological-activity relationship and mode of action studies.

Dendrimers are highly branched synthetic polymers. It consists of enter core, integral region and numerous functional end groups. The growth of polymer occurs in outward direction from central core by stepwise polymerization. It is characterized with numerous cavities in the core structure creating channels and cages. Precise control of size can be achieved by the extent of polymerization. The intracellular uptake of dendrimers by receptor mediated endocytosis can be aided using the conjugation of biotin (Tomalia et al., 1985). Dendrimers contribute to drug delivery either by binding the drug on the periphery as prodrug, or entrapping the drug in the center core. Recent progress has been made to dendrimer formulary as a biocompatible drug carrier for cancer targeting therapy.
