A capture device for particles in air and manipulating their position in space

摘要

Technical Solution device for capturing microparticles in the air, and manipulating them in the position space refers to a singular optics and can be used in devices capture microparticles in modern biology, medicine and biomedical engineering, for example, alignment systems mikrooptomehanicheskih sorting biological cells, etc. The apparatus comprises a laser, disposed successively along the beam a converging lens, a diffractive screen, with holes regularly spaced around the central hole; a focusing lens, a glass cuvette, filled with a suspension of carbon particles, a projection lens and a recorder. The apparatus allows the formation of an array of optical traps, the size of which can be adapted to the size of the captured object, perform a stable three-dimensional capture microparticles perform rotation and movement of the entrained particles in a gaseous medium.
