Algae-Based Microrobots Deliver Antibiotics within Lungs

Medgadget: Researchers at the University of California San Diego have developed a microrobot system to treat bacterial pneumonia. The microrobots consist of living algal cells that can swim very effectively in biological fluids, allowing them to navigate throughout the lungs…

Soft Robot Biodegrades Inside Body

Medgadget: Researchers at the City University of Hong Kong have developed a magnetic soft millirobot that can grab and release objects, and move around by rolling. The device can be controlled using magnetic fields, and consists of a biodegradable gelatin and iron oxide microparticles. The technology has significant potential…

Granular Hydrogels for Improved Bioinks

Medgadget: Researchers at Penn State have developed a granular hydrogel that contains both hydrogel microparticles and self-assembling nanoparticles, and which could be highly suited for bioprinting purposes. The concept involves the nanoparticles becoming adsorbed onto the hydrogel microparticles and reversibly…

Ultrasound Stickers Look Inside the Body

IEEE Spectrum: A wearable ultrasound sticker roughly the size of a postage stamp could help enable continuous medical imaging of internal organs for patients on the move, a new study finds. Ultrasound imaging is one of the most common medical tools…
