Manipulation of a micro-object by using an optically driven mircroneedle.
Fig 5.(a) Pushing a micro-object with an arm of the microneedle.
Fig 5.(b) Pricking a micro-object with a submicron probe tip of the microneedle.
The probe tip was sufficiently strong to prick the micro-object.
The elongation of individual polymers is observed through use of fluorescently labeled DNA molecule
