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. WebOptical traps can produce forces in the microdyne range on intact cells without causing overt damage: such forces are sufficient to arrest actively swimming bacteria 2 and can overcome torque...
