Due to their adaptability to the surrounding environment, soft microrobots have developed various therapeutic applications in the medical field, including vascular clearance, cell transport, and drug delivery. However, most soft microrobots cannot quickly enter, retrieve, and maintain their original position once the external driving field is removed. To address this, Guannan He from China Medical … Read more
iNature Self-assembling hydrogels for mechanical support and drug delivery have been widely studied in the context of traumatic brain injury (TBI). However, most self-assembling hydrogels rely on polymer carriers or the introduction of exogenous inactive substances, often raising biosafety concerns and making clinical translation difficult. On October 9, 2024, a research paper titled “Small Molecule … Read more
