In this review, the focus is put on modern approaches in the biological sciences and their developments in different fields. We provide a comprehensive and categorized review of molecular and cellular technologies; Gaussian Chromatin Conformation Capture and in silico drug target organism models, which have greatly enhanced the under- standing of gene regulation and Targeted Drug Discovery. In particular, new opportunities for the application of monoclonal antibodies and other new compounds like thymol in chitosan systems indicate the indefinite opportunities for the development of medical applications.
