Infrared spectromicroscopy at and below the diffraction limit
Description:
Infrared spectroscopy has been an essential analytical technique in many scientific fields ranging from astrophysics through materials science to biomedical research. The combination of IR spectroscopy and far-field microscopy enabled scientists to look at fine details using thermal sources and eventually reach diffraction-limited spatial resolution using synchrotrons and, more recently, broadband and tunable IR lasers. The limitations imposed by the laws of physics in the far field were first overcome by scanning probe detection of light in the visible and IR ranges. Recently, a new technique (OPTIR) probing the photothermal effect induced by an IR pulse using short-wavelength light was introduced, which combines the ease of optical microscopy and the power of IR spectroscopy at the visible diffraction limit. The SMIS beamline has been at the forefront of developing and adapting high-performance IR spectromicroscopy techniques through the user community. In this seminar I will highlight relevant experiments on neuroscience, cosmetology research, and art conservation, making use of the combination of the broadband synchrotron source and sub-diffraction resolution techniques, such as OPTIR.
Speaker: Ferenc Borondics - SOLEIL Synchrotron
Ferenc Borondics, educated as a chemist in Hungary, has been working in synchrotrons around the world since 2007 at infrared and various x-ray beamlines. His main interests are method development, materials science and the application of novel machine learning techniques in spectroscopy. Currently, he is heading the SMIS infrared spectromicroscopy beamline in the SOLEIL synchrotron in France. The SMIS beamline was an early adopter of OPTIR spectromicroscopy and, through its user community, is one of the leading facilities in the using the technique.
