Résumé

We design and fabricate optically driven micromachines which find the applications in microfluidics, manipulation of biological cells, microchemistry etc. The micromachines are driven by tightly focused laser beams. To aid the design of micromachines, we employ a number of modeling methods such as the Mie theory, the point matching method, finite difference methods, discrete dipole approximation (FDFD), sometimes in combination, to simulate the light scattering from the individual components. The micromachines prototypes are fabricated using a two-photon polymerization process.
