Interaction of Au as a nano sensor with glutamate amino acid: A quantum chemical study

Understanding the nature of interaction between metal nanoparticles and a biomolecules suchas amino acid is so important in improvement and new design of biosensors. In this studyinteraction of different conformers of glutamate amino acid in nutral and anionic form andAu nano particles has been investigated with using density functional theory. The 6-31+G*basis set was used for the atoms in glutamate while for Au atom effective core potential(ECP) Lanl2DZ basis set was applied.
