What happens when you can get IR spectra at the nanoscale?
Dr. Derek Nowak discusses PiFM, an AFM-IR-based technique, to explain how IR spectroscopy and imaging can be extended to the nanoscale. With sub 5 nm lateral resolution and single-molecule-level sensitivity, PiFM opens up a wide variety of research avenues ranging from exploring nano-crystallin structures for drug delivery to process/failure analysis in semiconductor nanofabrication.
