Surface-enhanced Raman scattering (SERS) is a spectroscopic technique which combines modern laser spectroscopy with the exciting optical properties of metallic nanostructures, resulting in strongly increased Raman signals when molecules are attached to nanometre-sized gold and silver structures. The effect provides the structural information content of Raman spectroscopy together with ultrasensitive detection limits, allowing Raman spectroscopy of single molecules. Since SERS takes place in the local fields of metallic nanostructures, the lateral resolution of the technique is determined by the confinement of the local fields, which can be two orders of magnitude better than the diffraction limit. Moreover, SERS is an analytical technique, which can give information on surface and interface processes. SERS opens up exciting opportunities in the field of biophysical and biomedical spectroscopy, where it provides ultrasensitive detection and characterization of biophysically/biomedically relevant molecules and processes as well as a vibrational spectroscopy with extremely high spatial resolution.

The article briefly introduces the SERS effect and reviews contemporary SERS studies in biophysics/biochemistry and in life sciences. Potential and limitations of the technique are briefly discussed. Export citation and abstract.

(307261) 2002 MS 4 is a large, the second-largest known object in the Solar System without a name, after. It was discovered in 2002. Brown's website lists it as to be a. The estimated it to have a diameter of 000000000♠726 ±123 km. The Herschel team estimates it to be 000000000♠934 ±47 km, which would make it one of the 10 largest TNOs currently known and large enough to be considered a dwarf planet under the of the. It is currently 47.2 AU from the Sun and will come to in 2123. It has been observed 55 times, with images back to April 8, 1954.
