WebNov 10, 2024 · Optical Tweezers can also be useful to investigate the folding cooperativity in proteins with multiple domains. This feature is crucial in molecular biology, since a lower cooperative communication between the different domains of a protein could increase the population of partially folded proteins and consequently promote misfolding diseases. WebAn optical tweezer uses the forces exerted by a strongly focused beam of light to trap, manipulate, and transform a small volume of matter. Originally introduced by Bell Labs researchers in 1986, optical tweezers have become indispensible tools for research in physics, chemistry and biology.
