The evidence indicates that non-invasive monitoring (near-infrared spectroscopy; NIRS) of oxygen in brain tissue likely does not reduce death rates or short-term brain problems for very premature ...

Standard optical microscopes can’t see objects smaller than half the wavelength of visible light. To get around this, scientists use a technique called scattering-type scanning near-field optical ...

A novel spectroscopic method developed at Institute of Science Tokyo, Japan, enables highly sensitive analysis of molecules at material interfaces, using a combination of conventional ATR-IR, precise ...
