Chemically resolved imaging of biological cells and thin films by infrared scanning near-field optical microscopy.
The infrared (IR) absorption of a biological system can potentially report on fundamentally important microchemical properties. For example, molecular IR profiles are known to change during increases in metabolic flux, protein phosphorylation, or proteolytic cleavage. However, practical implementation of intracellular IR imaging has been problematic because the diffraction limit of conventional...
متن کاملShedding Near-Infrared Light on Brain Networks
Near-infrared spectroscopy is a novel and promising technology for cost effective and noninvasive brain imaging in research and clinical practice. Utilizing the fact that near-infrared light is mostly absorbed by tissue hemoglobin, one can measure the intensity of light scattered and reflected by tissue (e.g., brain) to track local changes in hemoglobin concentrations within cortical layers (ne...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملFunctional Near Infrared Whole Brain Imaging
21 While Near infrared (NIR) spectroscopy has been increasingly used to detect stimulated brain 22 activities with an advantage of dissociating regional oxy-([HbO]) and deoxy-hemoglobin ([Hb]) 23 concentrations simultaneously, it has not been utilized much in pain research. Here, we 24 investigated and demonstrated the feasibility of using this technique to obtain whole-brain 25 hemodynamics in...
متن کاملTime-resolved second harmonic generation near-field scanning optical microscopy.
Novel scanning probe microscopy (SPM) spectroscopic techniques are currently receiving much attention. The increasing number of spectroscopic techniques, when combined with the high spatial resolution that is attainable with SPM, makes it possible to probe a large range of material characteristics on the nanoscopic scale. The ability to probe samples on the nanoscale with femtosecond time resol...
