Application of Raman spectroscopy from condense matter to biology

With the advent of nanotechnology, the scope of application of Raman spectroscopy has extended beyond being a mere spectroscopic/characterization tool. Unfortunately, the full potential of Raman spectroscopy remains unexplored. Due to the ease of application and its ability to decipher interconnection with electronic states and spin states along with structural and vibrational properties, Raman spectroscopy has an edge over many other tools available and can be used to investigate the microscopic origin of molecular properties. The talk will discuss such potentials of Raman spectroscopy based on studies conducted on molecules of importance in condensed matter physics/biology. The first example is that of 1T–TiTe2, a prominent layered 2D system topological insulator. The multiple indirect signatures of electronic transition in 1T–TiTe2 will be discussed in connection with the recent theoretical proposal for 1T–TiTe2, and also the possibility of an electronic topological transition from electronic Fermi surface calculations. The talk will also discuss the use of Raman spectroscopy in the investigation of molecular-level changes in the zeolitic imidazolate framework ZIF-8, as a function of temperature. Further delving into the applications of Raman spectroscopy in biology, the talk will highlight the use of surface enhanced Raman spectroscopy (SERS) in understanding the selective inhibition of oncogenic Aurora A Kinase by Felodipine.
