The goal of biological chemistry is to advance our knowledge of the molecular mechanisms of biochemical processes by applying the principles of chemistry to biological systems. Research areas in the Biological Chemistry Division encompass Structural Biology experiments on proteins and nucleic acids by using X-ray Crystallography and NMR Spectroscopy, Mass Spectrometry-based quantitative Proteomics and Metabolomics, and the development of Biosensors utilizing Nanodevices and optics. Our basic research findings are translated into the bases for medical applications in disease diagnostics and noble drug design.
