WebIn the 21st century, optical manipulation has expanded its unique capabilities, enabling not only a more detailed study of single molecules and single cells but also of more complex … WebHowever, AFM relies upon physical contact between a probe on a stiff cantilever and the substance of interest, which can easily damage the soft tissues found in biological samples. Measuring force through a probe in an optical trap, however, can be exceedingly gentle in comparison, with the force adjustable through changing laser power. dethroned black midi
