Manipulation of biological cells becomes increasingly important in biomedical engineering to address challenge issues in cell-cell interaction, drug discovery, and tissue engineering. Significant demand for both accuracy and productivity in cell manipulation highlights the need for automated cell transportation with integrated robotics and micro/nano manipulation technologies. Optical tweezers,...

The invention of metamaterials prompts reconsideration of a number of fundamental physical phenomena and enables a variety of unique properties and functionalities. These include negative refractive index, magnetism at optical frequencies, sub-wavelength resolution, “backward” phase matching conditions for nonlinear optical processes, and even rendering objects invisible – cloaking. In this bri...
