The advantages of these techniques mainly rest on the possibility of
exerting mechanical control over the trapped polymer, thus enabling the study of interaction dynamics versus forces or torques.
«Optomechanics is an area of research in which extremely minute forces
exerted by light (for example: radiation pressure, gradient force, electrostriction) are used to generate and
control high - frequency
mechanical vibrations of microscale and nanoscale devices,» explained Gaurav Bahl, an assistant professor of
mechanical science and engineering at Illinois.
