An intelligent soft material that curls under pressure or expands when stretched

Researchers have printed liquid metal circuits onto a single piece of soft polymer, creating an intelligent material that curls under pressure or mechanical strain.

Treating rheumatoid arthritis with micromotors

Researchers have developed magnesium-based micromotors propelled by hydrogen bubbles, which improved rheumatoid arthritis symptoms when injected into the joints of rats.

An mRNA nanovaccine for cancer immunotherapy

Researchers have developed a graphene oxide hydrogel that, when injected into mice with melanoma, slowly released RNA nanovaccines that shrank tumors and kept them from metastasizing.

3D-printing perovskites on graphene makes next-gen X-ray detectors

By using 3D aerosol jet-printing to put perovskites on graphene, scientists have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health hazard of medical imaging devices.
