Sum Frequency Generation (SFG) Vibrational Spectroscopy

Sum Frequency Generation (SFG) Vibrational Spectroscopy

Introduction

Graphene has become a hot research topic, and its application has been extended to the areas of nano-biotechnology, such as nano-biomedicine, nano-biosensing, and nano-electronics, etc. These applications involve the interaction between proteins, peptides, DNA, RNA and graphene, so understanding such molecular interactions is crucial for the further research of graphene.

A variety of techniques have been developed for surface characterization, including scanning electron microscopy (SEM), tunneling electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS), but they all require high vacuum during operation, which limits the application of these technologies. Sum Frequency Generation (SFG) vibrational spectroscopy is similar to Raman spectroscopy, it can provide a variety of information about molecular functional groups at the surface or interface. Moreover, SFG can study various interfaces, including liquid-liquid, solid-solid, and liquid-solid interfaces. SFG has a wide range of applications, including materials science (polymers, electrochemistry) and life sciences (membrane, biological materials), etc. Due to its high surface/interface selectivity and versatility, it is becoming a highly potential tool in surface scientific research.
