摘要：

A numerical calculation method for the optical trapping force which is appropriate for single lensed fibre trapping (SLFT) is proposed. The piconewton optical trapping forces on a yeast cell in SLFT as a function of the position along two horizontal orthogonal axes are measured experimentally by static and dynamic methods, respectively. The order of magnitude and the characteristics of the theoretical trapping force curve calculated by our method are the same as those of the experimental measurement curve. The theoretical and experimental results for the angle of inclination of the fibre probe also coincide with each other.
