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. WebApr 10, 2024 · Importantly, the horizontal magnetic tweezers design based on a single permanent magnet has a number of advantages over traditionally used methods like optical tweezers: i) Operation under an intrinsic “open potential” force-feedback, e.g. at a force of 20 pN the force changes by only 40 fN µm −1 (see Supporting Information) allowing the ...
