The elastic modulus of the optical tweezers is easily determined by recorging the positional fluctuations of the captured beads with a high-speed camera and analyzing with a dedicated software.
The measurement range is limited to about 0.1 pN/nm for 1 mm diameter beads..
The measurement results should be a reference values..
The power of the incident beam should be set to 200mW or less (referenced at 1064nm).
Guide
