Scanning mechanisms that have application in confocal imaging use electromagnetic actuation to move elements in an optical system. An objective lens mounted to a flexure comprising a magnetic material is actuated in the axial direction by an electromagnet coil. An optical path may pass through the coil. Scanning in transverse directions may be provided using magnetically actuated flexible beams which move the tip of an optical fiber or other pinhole in one or more transverse directions. Actuators may be actuated using driving currents that include an AC component and a DC bias component. The scanning mechanisms may be miniaturized and may be constructed to provide real-time imaging.

Drug delivery devices responsive to at least one external stimulus are described, along with methods for their preparation and use. The devices can be configured to respond to the stimulus, providing 'on demand' release of one or more deliverables such as pharmaceutical drugs.

A microbial fuel cell includes a bio-compatible body having a micro-pillar structure defining an anode compartment adapted to contain a catalyst that metabolizes glucose to generate electrons and protons. A nano-porous membrane prevents loss of the catalyst from the anode compartment, while providing fluid access for ingress of glucose fuel and egress of waste.
