Light from a fibre laser at 1064nm was coupled into the waveguide, causing the polymer particles or cells to be propelled along the waveguide at a velocity which is dependent upon the laser power. A theoretical model was used to predict the propulsion velocity as a function of the refractive index of the particle. The experimental results obtained for the PMMA particles and the mammalian cells show that for input powers greater than 50mW the propulsion velocity is approximately that obtained by the theoretical model. For input powers of less than ∼50mW neither particles nor cells were propelled; this is considered to be a result of surface forces (which are not considered in the theoretical model). The results are discussed in light of the potential application of optical channel waveguides for bioanalytical applications, namely in the identification and sorting of mammalian cells from mixed populations without the need for fluorescence or antibody labels. 2011-10-23T14:20:46Z 2011-10-23T14:20:46Z 2011-01-23 Working Paper 978-0-8194-8466-6 0277-786X http://spiedigitallibrary.org/proceedings/resource/2/psisdg/7929/1/792909_1?isAuthorized=no http://hdl.handle.net/123456789/14816 en Proceedings of the Microfluidics, BioMEMS, and Medical Microsystems IX Society of Photo-Optical Instrumentation Engineers (SPIE) |
