Optical Tweezers in Human Cancers

Zhongliu Fangzhi Yanjiu
Optical tweezers are a means to manipulate objects with light. Optical tweezers can obtain a nanometer space, piconewton force, and a millisecond resolution; thus, they are excellently suited for studying biological processes from the single-cell to the ...

Optical manipulation and applications of quasi-one-dimensional nanomaterials

Materials & Design
Quasi-one-dimensional (quasi-1D) nanomaterials serve as essential building blocks for next-generation nanodevices, owing to their high specific surface area, strong quantum confinement, and highly tunable properties.

Micro-Dumbbells—A Versatile Tool for Optical Tweezers

Micromachines, 2018
Manipulation of micro- and nano-sized objects with optical tweezers is a well-established, albeit still evolving technique. While many objects can be trapped directly with focused laser beam(s), for some applications indirect manipulation with tweezers ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Design of Optical Tweezers Manipulation Control System Based on Novel Self-Organizing Fuzzy Cerebellar Model Neural Network

Applied Sciences, 2022
Holographic optical tweezers have unique non-physical contact and can manipulate and control single or multiple cells in a non-invasive way. In this paper, the dynamics model of the cells captured by the optical trap is analyzed, and a control system ...
