We achieve a three-dimensional stable trap of yeast cells by using the GIMMF optical tweezers. Compared with the single-mode fiber optical tweezers,the GIMMF optical tweezers possess large optical trapping forces. Owing to the freedom of the GIMMF length,the fabrication of the GIMMF optical tweezers is simple, repeatable, and highly efficient.
