You can use optical tweezers to trap and move microscopic objects in space using the attractive and repulsive forces exerted by a laser beam. For example, trap a microscopic polystyrene bead and guide it in proximity to a cell or trap small components within a multicellular organism to study cellular functions and properties.
Correlating the optical tweezers with fluorescence and label-free microscopy enables you to visualize every step of the cellular processes while at the same time measuring and manipulating them in real time. Use the optical tweezers – fluorescence and label-free microscopy, to study cellular properties in different contexts:
- Visualize how induced mechanical stimuli or stresses affect cell receptor responses;
- Measure forces associated with filopodia formation and functions;
- Manipulate small components and droplet fusion in a multicellular organism.
