Nanophotonics, Volume 11, Issue 7, Page 1413-1426, March 2022., 2022 Abstract It is the basic characteristic of pure vortex light that there is a phase singularity at the origin. Such a singularity may be multiple degenerate, which determines the order of vortex light. Singularities splitting phenomenon means that singularities no longer concentrate at the origin but distribute around the space, usually occurring in ...

Sensing and Bio-Sensing Research, 2019 Here, we present the development of aptasensor for the label-free, stable, and sensitive detection of environmental toxin microcystin-LR (MC-LR). A thiolated aptamer used as a bio-receptor was covalently immobilized on dual-resonance long-period fiber gratings (DR-LPFG) to detect MC-LR toxin.
