Changing Gears

For thousands of years, humans have used cogwheels and gears to turn everything from mill stones to clock hands to engines. But this new design – pushed around by light – churns microscopic particles as a prototype for a new kind of micromotor. The tiny gear (around 10,000 times smaller than a revolving door) is cut out of a polymer and placed on top of a photo-reactive material. A blast of light from above – using a device called optoelectronic tweezers – generates a force at the material’s surface. By rotating this light pattern – researchers call it a 'spanner' (shown in white) – the gear inside swooshes a swarm of particles along. Linked together into systems, micromotors have a bright future inside microfluidic devices, where clues to the behaviour of chemical currents around living cells may depend on their tiny revolutions.

Sperm tested as possible candidate for delivering cancer medications in female patients

A sperm-driven micromotor is presented as cargo-delivery system for the treatment of gynecological cancers. This particular hybrid micromotor is appealing to treat diseases in the female reproductive tract, the physiological environment that sperm cells are naturally adapted to swim in. Here, the single sperm cell serves as an active drug carrier and as driving force, taking advantage of its swimming capability, while a laser-printed microstructure coated with a nanometric layer of iron is used to guide and release the sperm in the desired area by an external magnet and structurally imposed mechanical actuation, respectively. The printed tubular microstructure features four arms which release the drug-loaded sperm cell in situ when they bend upon pushing against a tumor spheroid, resulting in the drug delivery, which occurs when the sperm squeezes through the cancer cells and fuses with cell membrane. Sperms also offer higher drug encapsulation capability and carrying stability compared to other nano and microcarriers, minimizing toxic effects and unwanted drug accumulation. Moreover, sperms neither express pathogenic proteins nor proliferate to form undesirable colonies, unlike other cells or microorganisms do, making this bio-hybrid system a unique and biocompatible cargo delivery platform for various biomedical applications, especially in gynecological healthcare.
