Abstract

The optical vortex beams carrying orbital angular momentum (OAM) recently have unveiled great potential to be widely applied in advanced biomedicine, e.g. manipulating and assembling DNA, detecting #biomolecule, organic illumination, single-cell #nanosurgery, etc. However, it is an everlasting challenge to produce the proper vortices devices for corresponding applications. To this end, the tunable properties of OAM beams need to be produced. The #spectrum-tunable property is related to the tuning of the response of target molecules. The OAM-tunable property can control the number and distribution of target particles. Moreover, the polarization-tunable property can be used to reduce #photodamage. Hereinafter, we give a prompt review of the recent advances on tunable vortex beam devices for biomedical applications Optical #vortex beams are at the heart of a number of novel research directions, which are the light beams with a helical wavefront carrying orbital #angular momentum (OAM), giving rise to a phase singularity at the center of light field [1-3]. In 2004, X Zhuang [4] unveiled that a DNA molecule can be manipulated by a vortex beam which plays a role of optical tweezer.
