NIBIB funded researchers have developed laser-activated nanomaterials that integrate with wounded tissues to form seals that are superior to sutures for containing body fluids and preventing bacterial infection. Tissue repair following injury or during surgery is conventionally performed with sutures and staples, which can cause tissue damage and complications, including infection. Glues and adhesives have…
ALS Researchers Develop Human Spinal Cords on a Chip
Aided by advanced stem cell technology and tissue chips, National Institutes of Health-funded researchers used stem cells originally derived from a person’s skin to recreate interactions between blood vessels and neurons that may occur early in the formation of the fetal human spinal cord. The results published in Stem Cell Reports suggest that the system…
Smart Nanoparticle Targets and Attacks Tumors
Bioengineers at the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a smart anti-cancer nanoparticle with precisely targeted tumor-killing activity superior to previous technologies. The state-of-the-art nanoparticle features an exceptionally sturdy shell capable of carrying large loads of chemotherapeutic drugs through the circulatory system to the tumor without the leakage that can damage…
