The submicron fiber is fabricated by drawing a single-mode optical fiber through a flame-heated treatment. Gold nanorods (length and middle-section diameter are 80 nm and 20 nm, respectively) are deposited on the designated position of the submicro fiber by the positioning function of optical microscope, and the local surface plasmon resonance (LSPR) of gold nanorods is excited by the evanescent wave around the fiber. When the optical power increases to 30 mW, due to strong plasmon absorption and photothermal conversion, a microbubble forms at the position of the fiber decorated with the gold nanorods. Therefore, the laser light at this position is absorbed by plasmon resonance and scattered by the bubble. Optical transmission is not observed behind the bubble. Polystyrene particles (900 nm in diameter) near the fiber can be trapped by the gradient force, and then delivered along the direction of light propagation due to the scattering force induced by the evanescent wave. Once the particles move to the position of the bubble, they will stop their advancing. This technology can be used for targeted delivery of microparticles.
