Tip-Enhanced Raman Scattering
Background The ability to identify small quantities of adsorbed analyte or structural features down to the few-molecule level is a key challenge in nanotechnology. Optical spectroscopy provides an attractive means to achieve such identification via noninvasive implementations and the potential for chemical sensitivity. Raman scattering has emerged as a particularly powerful technique due to its...

متن کاملTip-enhanced Raman spectroscopic detection of aptamers
Single molecule detection, sequencing and conformational mapping of aptamers are important for improving medical and biosensing technologies and for better understanding of biological processes at the molecular level. We obtain vibrational signals of single aptamers immobilized on gold substrates using tip-enhanced Raman spectroscopy (TERS). We compare topographic and optical signals and invest...
متن کاملRecent Advances in Tip-Enhanced Raman Spectroscopy.
Tip-enhanced Raman spectroscopy (TERS) has experienced tremendous growth in the last 5 years. Specifically, TER imaging has provided invaluable insight into the spatial distribution and properties of chemical species on a surface with spatial resolution that is otherwise unattainable by any other analytical method. Additionally, there has been further development in coupling ultrafast spectrosc...
