DESCRIPTION:Speakers: Nikiwe Mhlanga (Dr)\nSurface-enhanced Raman spectros
 copy (SERS) is a phenomenon that amplifies conventional Raman signal with 
 roughened metallic substrates.  Gold and silver metallic nanoparticles are
  commonly used as SERS substrates.  The application of SERS in diagnostics
  yields sensitivity\, multiplexing\, and quantification of disease causati
 ves.  However\, the understanding of the SERS architecture and mechanism i
 s still elusive.  Hence the use of density functional theory (DFT) to stud
 y its chemistry.  DFT is used to study the interaction of the metallic sub
 strates with SERS tags and biological molecules. The simulation results in
 form experimental work towards the fabrication of reproducible\, sensitive
 \, qualitative SERS biosensors.\n\nhttps://events.chpc.ac.za/event/98/cont
