Tractor Beams and Bacteria
Stanley Allen and Chris Hansen, Southern Adventist University
This talk will report on undergraduate research in optical trapping with
hopeful applications to bacterial study. We will follow-up on earlier research
which included basic apparatus assembly and attempted trapping. Since our
last report, we have improved our apparatus and reproducibly trapped small
spheres in solution. Calculations of our trapping force are encouraging
and we hope to soon trap and study bacteria.
