Cell is a basic unit of life structure and function,optical tweezers can manipulate yeast cell or red blood cell through the wall of capillary,realizing the manipulation of biological cell in capillary by optical tweezers along the axial and transverse beam and making its move along the transverse beam.We measured the optical trapping force of piconewton order on the yeast cell in capillary in our experiments.Optical tweezers can realize the manipulation of alive biological samples in a non-contacting and nondestructive way.
