HORIBA Scientific, global leader in Raman spectroscopy solutions, announces an innovative solution that addresses the challenges of TERS imaging.

Tip Enhanced Raman Scattering (TERS) is a technique that provides molecular information on the nanometer scale through the combination between a Raman spectrometer and a Scanning Probe Microscope. TERS has been hampered by extremely long acquisition times, measured in hours, required for collection of reasonably pixel density, and even with the last decade progress, TERS is still seen by the research community as a difficult too. In some extent, with older “TERS ready” systems offered until recently, the concerns were fairly valid.

HORIBA Scientific and AIST-NT now offer a solution that addresses all the instrumentation concerns and bring TERS as an analytical method to a completely new level today.

HORIBA Scientific and AIST-NT pioneered the demonstration of TERS in out –of-the –lab conditions for the second year at number of conferences worldwide. The XploRA Nano platform in the upright and side configuration, combination with AIST-NT’s SmartSPM and HORIBA’s XploRA spectrometer, offers a very compact (complete set up stands on 900 x 760 x 55 mm optical table), fully integrated and automated solution.

At the recent SPIE conference in San Diego, the XploRA Nano equipped, with AFM-TERS tips, showed nanoscale chemical imaging of a single carbon nanotube with a spatial resolution of 8 nm, confirmed from the section analysis of the intensity of the TERS bands. The images below show an onsite demonstration of TERS mapping of a single carbon nanotube, with an optical spatial resolution down to 8 nm. 

“The TERS image on the right, 100 x 100 nm scanning area, is obtained with a pixel step size of 1.3 nm, in a total acquisition time < 9 min, 100 ms per pixel, on the booth, without any active isolation table nor enclosure box, far away from ideal lab conditions,” explains Dr Marc Chaigneau, the AFM-Raman product manager, HORIBA Scientific. In this TERS map, the intensity of the D band (white and green pixels) shows the imperfection in the structure of the latter; in contrast, the areas in red correspond to the pure graphitic arrangement of the CNT through the intensity of the 2D band. Close to the local lattice defects (red circle on the map), a single step gives rise to noticeable intensity of the D peak, showing a chemical sensitivity down to 1.3 nm.”

The HORIBA Scientific TERS instrumentation is robust, compact, and easy-to-use. It is currently available for chemical imaging at the nanoscale for real world applications.
