Researchers at the University of California San Deigo have successfully used tiny micromotors loaded with antibiotics to treat a bacterial infection in the stomachs of mice, according to a study published today in Nature Communications. The tiny drug-delivery vehicles are powered by gastric acid, pushing them through the stomach and releasing cargo in a specific region, […]

Nanotech derived from amniotic stem cells could help treat brain cancer
Creative Medical Technology Holdings (OTC:CELZ) touted its exosome technology today, reporting that it demonstrated an ability to regenerate healthy brain cells while selectively halting the growth of glioma brain cancer cells in a preclinical model. The company’s exosomes are vesicles harvested from amniotic stem cell technology, which it licensed from the University of California San […]
Engineered tissue could eliminate radiation for bone marrow transplants
University of California San Diego engineers have created artificial bone tissue that could eliminate the need for radiation before bone marrow transplants. Shyni Varghese, a bioengineering professor at UC San Diego Jacobs School of Engineering, led a team to develop a bone-like implant to eliminate the pre-treatment radiation that kills stem cells in a patient’s bone […]
Microscopic submarines release drugs depending on acid concentration
Researchers have developed tiny ‘submarines’ that speed through the stomach using gastric acid for fuel. The proton-driven micromotors have a pH-sensitive polymer coating that can be loaded with drugs and released in the stomach. Gastric acid can be destructive for orally-administered, pH-sensitive pharmaceuticals, including antibiotics. Although some coatings can protect substances from gastric acid, they […]
Acoustic waves used to move fluid through nanoscale channels
Researchers from the University of California San Diego used acoustic waves to move fluids through small channels, marking the 1st time that surface acoustic waves have been used at the nanoscale. The team’s work was published this week in Advanced Functional Materials. The findings are an important step towards manufacturing small, portable devices for drug discovery […]
