N2 - We report a novel technique for the manipulation of biological cells and microparticles using light-actuated Marangoni tweezers (LAMT). Yeast cells and microparticles were trapped at a light intensity of 103-10 4 W/cm2 which is much lower than that required for optical tweezers. Particle manipulation using LAMT offers several advantages such as low power requirements, a trapping force scaling with the particle diameter d (instead of d3 as with conventional optical methods), and operation at vanishing refractive index contrast between the particle and the liquid.
