Optical tweezers system has emerged as an efficient tool to manipulate tiny particles in a
non-invasive way. Trapping stiffness, as an essential parameter of an optical potential well …

Optical tweezers (OTs), which generate a variety of fascinating beam patterns, allow
biologists to uncover the natural secrets of human life at single-cell level. Due to its gentle …

The superposition of a Gaussian mode and a Laguerre-Gauss mode with ℓ= 0, p≠ 0
generates the so-called bottle beam: a dark focus surrounded by a bright region. In this …

We have studied the interaction between the anticancer drug Actinomycin D (ActD) and the
