We investigate experimentally and theoretically the trapping of micro-and nanoparticles in the evanescent field surrounding a tapered optical fiber. We calculate the field distribution for optical fibre modes as the fiber diameter approaches cut-off, and show how combinations of modes may be used to control trapped particle dynamics, suggesting applications in particle-selective transport and trafficking. Lastly we show how the plasmon resonance of metallic nanoparticles can be exploited to achieve enhanced optical trapping. © 2011 OSA.
