Active-passive calibration of optical tweezers in viscoelastic media.
In order to use optical tweezers as a force measuring tool inside a viscoelastic medium such as the cytoplasm of a living cell, it is crucial to perform an exact force calibration within the complex medium. This is a nontrivial task, as many of the physical characteristics of the medium and probe, e.g., viscosity, elasticity, shape, and density, are often unknown. Here, we suggest how to calibr...
متن کاملOptimizing active and passive calibration of optical tweezers
To obtain quantitative information from optical trapping experiments it is essential to perform a precise force calibration. Therefore, sources of noise should be pinpointed and eliminated. Fourier analysis is routinely used to calibrate optical trapping assays because it is excellent for pinpointing high frequency noise. In addition, Allan variance analysis is particularly useful for quantifyi...
متن کاملmeasuring viscoelastic properties of Red Blood Cell using optical tweezers
Efforts have been made to study the behavior of complex materials in micrometer dimensions with various techniques. One of these methods is the use of optical tweezers for biophysical applications. Red blood cells, as the most abundant blood-forming cells, play an important role in the life of living organisms, and their unique mechanical properties are important. In this report, the study of s...

متن کاملOPTiCAL TwEEzERS CALibRATiON AND bACTERiAL ADHESiON
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...
