    摘要: Methods and apparatus that facilitate membrane-perturbing surface interactions for delivering a payload to a variety of cell types without resulting in a substantial loss in cell viability or alteration of endogenous cellular functions. In one example, an intracellular delivery tool comprises a microfluidic device (10) which includes a microfluidic flow channel (12) containing fluid therein and a membrane perturbing surface (22), in fluid communication with the microfluidic flow channel (12), with a plurality of perturbing features disposed thereon. An exemplary intracellular delivery method includes flowing a fluid containing cells therein along a membrane perturbing surface having a plurality of perturbing features disposed thereon, and delivering nanomaterial across a membrane of the cells in the fluid during and after contact between the cells and the membrane perturbing surface.

    摘要: Disclosed herein is a flexible robotic limb. The design may include a backbone with rolling-contact joints connected to one another by pulley structures and corresponding cord loops engaged with the pulley structures. One or more flexible actuators may be used to control a length between adjacent links of the rolling contact joints to control articulation of the flexible robotic limb while still permitting passive reconfiguration of the flexible robotic limb when it is not being actively articulated.
