Simultaneous calibration of optical tweezers spring constant and position detector response.
We demonstrate a fast and direct calibration method for systems using a single laser for optical tweezers and particle position detection. The method takes direct advantage of back-focal-plane interferometry measuring not an absolute but a differential position, i.e. the position of the trapped particle relative to the center of the optical tweezers. Therefore, a fast step-wise motion of the op...
متن کاملMeasurement of the DNA Spring Constant Using Optical Tweezers
An optical trap was used to measure the relationship between restoring force and displacement of a 1.26 μm polystyrene microsphere attached to a 3.5 kilobase-pair DNA strand. Fitting to a wormlike chain model, the persistence length of the DNA molecule was measured as 53.0± 11.6 nm, and the contour length was measured as 713 ± 36 nm. The Hookean spring constant of DNA, at small displacements, w...

EXECUTiVE SUMMARY In this project, we will be measuring the forces of the binding of bacteria. We will be working with Lactobacillus acidophilus NCFM, Lactobacillus galli narum 33199, Lactobacillus ruteri 23272, and Bifidobacterium. These bacteria are lactic acid bacteria and are used as probiotics. We also reviewed literature on the bacterial cell wall constituents and the properties of adhes...
متن کاملTweezPal - Optical tweezers analysis and calibration software
Optical tweezers, a powerful tool for optical trapping, micromanipulation and force transduction, have in recent years become a standard technique commonly used in many research laboratories and university courses. Knowledge about the optical force acting on a trapped object can be gained only after a calibration procedure which has to be performed (by an expert) for each type of trapped object...
