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 کاملMultilayered nano-prism vertex tips for tip-enhanced Raman spectroscopy and imaging.
We presented a scalable fabrication method for the preparation of multilayered nano-prism vertex (NV)-tips whose dimensions can be controlled for tip-enhanced Raman spectroscopy (TERS). The NV-tip had sharp vertices (diameter ~20 nm) originated from the chemical lift-off process after the angle-grinding process, enabling high resolution imaging. TERS measurements were performed on brilliant cre...

This review provides a detailed overview of the state of the art in tip-enhanced Raman spectroscopy (TERS) and focuses on its applications at the horizon including those in materials science, chemical science and biological science. The capabilities and potential of TERS are demonstrated by summarising major achievements of TERS applications in disparate fields of scientific research. Finally, ...
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...
