Optical Tweezers: How Light Becomes Tiny Hands

A deep dive into the Nobel-winning tool that uses a tightly focused laser to trap and manipulate microscopic objects. We’ll unpack the physics of gradient and scattering forces, the regimes of ray optics versus dipole approximation, and the practical tricks like holographic traps and optoelectronic tweezers. From measuring molecular motors in biology to arranging atomic quantum arrays, this episode reveals how light can hold, move, and even levitate the small world—and why wavelength choices (like 1064 nm) matter for keeping samples safe.Note:  This podcast was AI-generated, and sometimes AI can make mistakes.  Please double-check any critical information.Sponsored by Embersilk LLC
