A possible manipulation of a biological cell by a laser beam focused through optical fiber

Biological object could be trapped by a single laser beam from an optical f iber end inserted at an angle to a sample chamber. Separation/coupling of a n individual biological cell was easily achieved using plural optical fiber s. From these experimental results, we verify that fiber optic trapping tec hnology can provide new and novel tools for the manipulation of microorgani sms and cells without physical contact.
