The focus of the laser beam is often associated with its destructive power. However, there are other applications for laser beams. One of these applications is the creation of organic complexes, that can have biomedical benefits. A team of researchers led by S.V. Kochemirovskaia at the Peter the Great St. Petersburg Polytechnic University have recently published new data on the effect of a laser beam on a sensitive porous material with a highly developed surface.

A laser beam placed in a solution of transition metal complexes initiates reduction reactions of pure metal at the interface between the solution and the dielectric substrate. This property of a laser beam helps to create microscopic sensors for analyzing human blood, nanocatalysts for organic reactions, and extracting microscopic amounts of precious metals from ballast rocks. The process, called Methods: Laser Induced Chemical Liquid Phase Deposition (LCLD) proceeds with varying efficiency in different solutions. The most interesting results are obtained when the solution contains two metals and some amount of ligand is insufficient to form two metal complexes. In this case, the two metals form a bimetallic complex containing one ligand and two nuclei. The team have deciphered these unusual structures by spectroscopic methods. They then studied the nanostructures that are formed during the decomposition of these complexes at the focus of the laser beam. The results of the work create a new additive nanotechnology, the application of which can be found in various areas of modern nanochemistry. The complete results have been published in the Bentham Science journal, Current Organocatalysis.
