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.
