Optical tweezers are important tools that are used in several scientific fields. An optical tweezers demonstration was developed by testing several different lasers, particles, and particle environments. The final product was a semienclosed 3D-printed casing with a sooted base plate. This demonstration picked up soot particles using a 250-mW 650-nm laser coupled to a 29-mm diopter focusing lens by Edmund Optics [1].
