We obtain RAMAN-TERS measurements

The central services of the University of Valladolid (UVA), supporting all areas and departments of the university, signed an agreement with Álava Ingenieros to hire equipment from our partner HORIBA that encompasses RAMAN and AFM technologies and also allows TERS (Tip Enhanced Raman Spectroscopy) measurements, combining both techniques at the same time.  

The system consists of a state-of-the-art confocal Raman microscope, with high spectral resolution and new image processing technologies that make Raman imaging even easier and faster, and a high-performance AFM microscope, which allows structural, mechanical, electrical and magnetic characterizations at nanometer scales. - Antonio Javier Zambrano.

"Both systems are coupled using a specifically designed optical system that, together with the use of special tips developed by Horiba, allow to quickly and easily obtain TERS measurements, thus obtaining chemical information of the samples at nanometer scales, in a non-invasive and non-destructive way, and with minimal sample preparation, in fields such as biology, chemistry, physical chemistry, materials, nanoparticles and nanotechnology, etc."- Juan José Romero. Thus, for example, it has been possible to measure the Raman spectrum of carbon nanotubes in specific areas of the same without destroying them, obtaining measurements of the size of the AFM tip (approx. 10 nm).

Currently, Horiba is the manufacturer with the most developed technology in this type of technique, with more than 35 publications on it.
