Researchers from UCLA's Jonsson Comprehensive Cancer Center have developed an innovative cancer-fighting technique in which custom-designed nanoparticles carry chemotherapy drugs directly to tumor cells...
Innovative contact lens delivers glaucoma medication continuously for a month
For nearly half a century, contact lenses have been proposed as a means of ocular drug delivery that may someday replace eye drops, but...
DNA ‘cages’ may aid drug delivery
Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report...
Eye injections may be needed less often
Johns Hopkins biomedical engineers have teamed up with clinicians to create a new drug-delivery strategy for a type of central vision loss caused by...
More intestinal cells can absorb larger particles
The small intestine employs more cells and mechanisms than scientists previously thought to absorb relatively large particles, such as those that could encapsulate protein-based...
Silk microneedles deliver controlled-release drugs painlessly
Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and...
First Virtual Stomach Explores Drug Delivery
Researchers have developed the first virtual stomach, a computer-generated model that is providing unique insights into the way medicines are released from pills and capsules. "There's no other technique to allow you to see flow patterns in a real stomach, animal or human," said lead researcher James G. Brasseur, Ph.D., a professor of mechanical engineering and bioengineering at The Pennsylvania State University. Although pills and tablets have become a ubiquitous part of our society, the detail of how the stomach breaks them down to help release their medicine remains unclear. "You can give someone a drug and measure its uptake in tissue," he said, "but the process between administering the drug and the uptake is largely guesswork."
