Abstract
- In the process of fiber optic tweezer manipulating cells, an adjustable and long working distance is very important for cell capture. To address this issue, a graded-index fiber (GIF) optical tweezer based on a UV glue cavity is proposed in this paper, and its ability to capture yeast cells was characterized. The initial air cavity between the single-mode fiber (SMF) and the GIF cone is filled with ultraviolet glue. By adjusting the length of the ultraviolet glue cavity and the laser power, the manipulation distance of the cells can be controlled. The light field distribution of the UV glue cavity is numerically investigated, which is compared with that of the GIF optical tweezers based on conventional air cavity. The contrastive result proved that the UV glue filled between the SMF and the GIF has a longer working distance than the original air cavity. The experimental results indicate that the fiber optical tweezer has a good capture distance controllability. The fiber optical tweezer also has the advantages of simple structure and convenient operation. [ABSTRACT FROM AUTHOR]
