This article presents the results of numerical modeling and experimental prototyping of an acoustofluidic microchannel structure for the separation of microparticles suspended in a liquid medium. A two-dimensional model was developed to analyze the influence of geometric and physical parameters on the formation of the acoustic field within the microchannel and the efficiency of particle separation.
This paper presents the main aspects regarding the production of biodegradable microspheres, the optimization of parameters in the drug encapsulation process, the techniques available for polymeric systems sterilization and the effects of γ-irradiation on microparticles.
In the article on an example from expert practice the considered methods of forensic еxamination of microparticless of platinum. An exposure and separation of microparticless of platinum from mechanical mixture of other metallic microparticless conducted with the use of methods of optical microscopy, magnetic separation and chemical dissolution of metals.
For the decision of diagnostic and identification questions the method of emission spectrology was used.
