ABSTRACT:
The present invention provides a device for trapping or stretching a microscopic substance comprising (a) a light source; (b) an acousto-optic modulator (AOM); (c)a beam-expander; (d) an object lens; and (e) an incoherent light source. The present invention further provides a method for trapping or stretching a microscopic substance comprising (a) providing a focused laser beam to form a focal spot and (b) scanning a plurality of points on said microscopic substance by said focal spot by way of the AOM.
