Abstract

Summary form only. Higurashi et al. (see Appl. Phys. Lett., vol. 64, p. 2209, 1994) realized the directional rotation of an asymmetrically shaped object using a single beam, but the rotational direction depended on the asymmetric shape of the object. In this paper, a novel technique to manipulate a biological cell using plural optical fibers was demonstrated and discussed. Yeast cells dispersed in water solution were used as the sample biological objects. We show the experimental results of the directional manipulation of a yeast cell.
