Optical tweezers setup
WebSamples for the optical tweezers kit are simple to prepare. A sample containing 1 µm or 3 µm glass beads is useful, as these are well-suited for getting to know the operation and handling of the optical tweezers. Alternatively, an emulsion of cream in water will also produce particles that can be captured with the optical tweezers kit. WebOct 1, 2024 · An optical tweezers setup is an ideal tool to trap and manipulate micro and nanoparticles in liquid solutions with nanometer accuracy and to measure and apply piconewtonian forces [14]. Experimentally, optical trapping is achieved by focussing a laser beam to the diffraction limit by an objective lens with a high numerical aperture. For this ...
