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.
