Laser Science TouchRaman Spectroscopy and Its Future in Science

With Raman spectroscopy, laboratory technicians with very little training can very exactly measure the properties and other traits of matter in any phase (gas, liquid or solid). Its potential uses have shown more and more potential in a growing number of industries. How It WorksHigh-precision Raman measuring tools gather data about substances at the micron scope. Usually, a laser is shined upon the subject material. The laser beam will refract uniquely depending on the material it hits. Observing the scatter makes it possible to map traits of the substance or substances being observed, their level of concentration, and other traits. The technique -- which is actually a collection of different measuring approaches -- is named after the Raman effect, which is where electromagnetic waves collide with a molecule and affect its bonds. To start out with, a monochromatic wave of light is used, making it possible to interpret the end result. ApplicationsThe most common application of TouchRaman spectroscopy is in the field of chemistry because it gathers its information from interacting with chemical bonds. However, its applicability is wide-ranging. In the pharmaceutical industry, specialized devices such as TouchRaman probes are used to identify active ingredients in medications, and what form those ingredients have at the molecular scale. TouchRaman tools such as these can also be crucial in physics experiments to determine the molecular state of materials, as well as measure their temperature. Some TouchRaman probes can even compile data regarding corrosive materials that would ordinarily damage the measuring device. Spatially Offset Raman SpectroscopyAnother type of Raman spectroscopy, called "spatially offset Raman spectroscopy," is less sensitive to surface layers and can be applied to, for example, notice counterfeit medications without opening their containing packages. They can also be utilized to monitor biological tissue, like an ultrasound. Experiments are under way to see if different TouchRaman and similar instruments can be utilized to identify the presence of explosive materials from a distance, and even to ascertain whether individual cells in the body are cancerous, which could make surgery much less dangerous and more precise, boosting favorable prognoses. MicrospectroscopyRaman spectroscopy can be utilized to examine minerals, proteins, and forensics evidence on a microscopic level. It can even be used to measure the amount of cholesterol or other substances in foods. CustomizationWhile manufacturers such as raman products sometimes sell premade TouchRaman and similar devices to government, academic and pharmaceutical organizations, those manufacturers are also able to specialize and build machinery optimally attuned to the measurement and observation needs of the individual order.
