Манипуляция биологическими микрообъектами оптическими пинцетами различных типов

The experimental results on the vortical light fields formation in the shape of various curves and their use for deformation and rotation of trapped microobjects such as latex, yeast cells, erythrocytes, bacillus subtilis, lacto bacillus cells and others are presented. Also the effective method of the optical trap arrays formation by the use of the diffraction grating is proposed. The dynamic change of the traps spatial position is realized by means of the grating turning. The method is of interest for the stretching and bending of the filament and spherical biological objects.
