Laser trapping has been widely applied for the confinement and physiological study of biological cells [1-2] and organelles [3]. In mammal fertility research, single spot laser tweezers were successfully utilized to trap individual sperm and quantitatively evaluate the motile force generated by a sperm [4, 5]. With the help of laser tweezers, the relationship between sperm motility and swimming behavior were revealed [5] and the effects of medical approaches on sperm activity were investigated [6, 7].
As sperm chemotaxis draws increasing interests in fertility research, the study on sperm-egg communication may help to explain infertility and provide new approaches to contraception [8]. While single spot laser trap can only be used to investigate one target at a time, greatly limiting the experimental efficiency and throughput, a ring-shaped laser trap, if feasible, could not only trap multiple samples at the same time, but also provide an equal-distance (from the center) condition, which is essential and perfect for biological tropism study.
Here we present a novel annular laser trap based on axicons for sperm chemotaxis study. Experiment with 15 micron polystyrene spheres shows the feasibility and performance of the system. With chemoattractant located in the center and sperms approaching from all directions, the annular laser trapping could serve as a sperm sifter for fertility sorting. When an additional pair of axicons is introduced into the optics, the first of which shifts along the optical axis back and forth, the diameter of the annular trap can be dynamically tuned from 130 micron to 428 micron, providing a real time variation on experimental condition for critical power analysis. This new scheme of optical trapping will bring high efficiency and fresh perspective to a vast variety of bio-tropism (phototaxis, geotaxis, galvanotaxis, etc.) research.
