Super-resolution optical microscopy and optical trapping of nanoparticles in the vacuum chamber of a scanning electron microscope KU Leuven
In 1986, Ashkin and coworkers proposed the use of tightly focused laser beams to manipulate individual micro-scale objects such as microparticles. Typically, micro- and nano-scale objects freely diffuse in the bulk solution. In the presence of an optical field, the particles can be trapped in the focal spot as a trapping potential is generated there. When several nanoparticles are trapped, they will generate an assembly inside the focus. ...
