Abstract

A nondestructive and noncontact method to trap and manipulate a microparticle in solution is proposed by utilizing femtosecond laser-induced nonlinear phenomena. A 90 μm diameter polystyrene bead in solution was trapped and manipulated by scanning femtosecond laser pulses around it, which was ascribed to shockwave, cavitation bubble, and jet flow. The maximum mechanical force exerted by laser irradiation was estimated to be over 1 μN. In comparison with conventional optical tweezers, this method provides not only a much larger trapping force but also a noninvasive advantage. [ABSTRACT FROM AUTHOR]
