Scientists have recently invented a revolutionary new way of detecting chemicals and biological matter even if there is only a single molecule present. The method involves combining surface enhanced Raman scattering (SERS) and slippery liquid infused porous surface (SLIPS) to allow the detection of a substance whether they it is dispersed in air, liquid or on a solid. By using the SLIPS to let a liquid carrier evaporate uniformly the substance that you want to detect will concentrate itself on certain areas which allows SERS to easily detect the substance even if there are only a few molecules present. This technology will help improve all kinds of analysis and research from forensics to environmental chemistry. Most other methods that do something similar requires the substance to be carried in water limiting the uses in most circumstances but the versatility of this method ensures that it can be used in almost any situation.
