Drug Delivery & Dispensing

At the 245th National Meeting & Exposition of the American Chemical Society, in New Orleans, scientists from the University of California, San Diego, described their advances in micromotor technology that, they say, could open the door to broad new medical uses.

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS), Cambridge, MA, have developed an inexpensive tactile sensor for robotic hands that is sensitive enough to enable a machine to handle objects with sensitivity and dexterity. Designed by researchers in the Harvard Biorobotics Laboratory,...

Scientists at Carnegie Mellon University, Pittsburgh, PA, are developing edible electronic devices that can be implanted in the body, and say that the device could be programmed and deployed in the gastrointestinal tract or the small intestine and once the battery packaging is in place,...

Researchers say that a new type of soft material they have created by using a unique 3D printer connects thousands of water droplets, 50 microns in diameter each, encapsulated within lipid (fat) films, which can perform some of the functions of the cells inside our bodies. These printed “droplet networks,” they say...

A new study done at the Johns Hopkins Children’s Center, Baltimore, MD, described online in JAMA Pediatrics, show that in children catheters inserted in a vessel in the arm or leg and not threaded into a large vein near the heart are nearly four times as likely to dislodge, cause vein inflammation, or...

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University, Boston, MA, were awarded a $9.25 million contract from the Defense Advanced Research Projects Agency (DARPA) to further advance a blood-cleansing technology developed at the Institute with prior DARPA support, and help...

Researchers at the University of Pittsburgh, with the support of a $3.4 million National Institutes of Health grant, are working to develop an artificial lung to serve as a bridge to transplant or recovery in patients with acute and chronic lung failure. The project aims to develop a compact respiratory...

A new study by researchers at Princeton University, Princeton, NJ, examined how bacteria clogs medical devices, and found that the microbes join to create slimy ribbons that form tangles, trapping other bacteria, and creating a full blockage in a very short period of time. Their findings, they say, could...

Scientists at King's College London say they have demonstrated the ability to deliver a dried live vaccine to the skin without using a traditional needle. They also state that this technique is powerful enough to enable specialized immune cells in the skin to kick-start the immunizing...

A specialized 3D printing process, using human stem cells, could pave the way to building custom replacement organs for patients, eliminating the need for organ donation, immune system suppression, and possible transplant rejection. Sound fantastic? The new valve-based technique, developed by the biomedical...

Scientists at the Institut de Recherches Cliniques de Montréal (IRCM), Canada, a world-renowned biomedical research center, were the first to conduct a trial comparing a dual-hormone artificial pancreas with conventional diabetes treatment using an insulin pump. Their research showed improved glucose...

Tucked within the Affordable Care Act is a provision requiring insurance companies to cover breast pumps. Insurers must pay for the new benefit, but the law doesn’t specify whether insurers must cover certain brands or types of breast pumps. It directs health plans to pay for “the costs of...

Vaccines usually consist of inactivated viruses that prompt the immune system to launch a strong defense if it encounters an active virus. But, for certain viruses, like HIV, even this is taking too much of a chance. In recent years, scientists have been exploring DNA as a potential alternative vaccine....
