WebOptical tweezers have emerged as a powerful tool for the non-invasive trapping and manipulation of colloidal particles and biological cells 1,2 . However, the diffraction limit precludes the low-power trapping of nanometre-scale objects. Substantially increasing the laser power can provide enough trapping potential depth to trap nanoscale objects.
