The article discusses influence of laser radiation on structure of insulin solution. We monitored changes in the structure of insulin solutions by means of analysis of crystallograms with a nanometer resolution probe microscope as well as by correlation processing of speckle patterns obtained by passing laser radiation through the solution. It was experimentally shown that laser radiation promoted solution homogenization by changing size of macromolecular clusters.
