Application of optical tweezers in life science

Due to their non-contact and non-invasion characteristics and a trapping force just in the range of bio-molecular interactions, optical tweezers are finding more and more applications in the measurement of interactions between biological macro-molecules. We describe in detail the development of optical tweezers and their typical applications in the life sciences. It is shown that the activity and mechanisms of bio-molecules can be revealed and understood in new depth with the use of optical tweezers.
