Study: Drug-delivery micromotors treat bacterial infection in stomach

August 16, 2017 By Sarah Faulkner

Micromotors for drug delivery

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, […]

Engineered tissue could eliminate radiation for bone marrow transplants

May 15, 2017 By Danielle Kirsh

engineered bone tissue

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

January 25, 2017 By Sarah Faulkner

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

November 15, 2016 By Sarah Faulkner

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 […]
