Researchers at MIT have developed a new material that shows promise for use in ultra-long drug delivery systems, as well as electronic monitoring of the stomach and weight-loss intervention. A type of polymer gel, the material is flexible and pH-responsive, allowing it to reside in the stomach for long periods of time before safety dissolving in the small intestine.
Building on previous work, researchers at Duke University have developed a new technology that wraps nanoshells in a thin film of drug-infused hydrogel, adding additional firepower to the already promising targeted cancer treatment. The hydrogel is loaded with cancer-fighting drugs and coated onto the nanoshells, which heat up when exposed to infrared light and release the chemotherapeutic drugs, delivering a one-two punch, directly to the tumour.
Scientists believe they can isolate the medical benefits of THC from the "unwanted side effects". By blocking a particular receptor, the cognitive effects of THC, including memory loss, anxiety and dependence can be suppressed, whist the analgesic and tumor-inhibiting properties remain.
When asked to name an endangered species, rhinos are probably one of the
first animals to come to most peoples' minds. In both Africa and Asia,
poaching is causing populations to plummet, due mainly to demand for
rhino horn as an ingredient in traditional Asian medicine – whether or
not it actually has any medicinal value is another question
altogether. In any case, San Francisco-based biotech startup Pembient is
developing what it hopes could be a solution: inexpensive bioengineered
rhino horn, which could out-compete the genuine item.
And you thought that regular pill bottles were hard to open ... a new
overdose-proof medication dispenser developed by a team of mechanical
engineering students at Johns Hopkins University can't be opened even
with the help of a hammer or drill. It does, however, deliver the proper
dosage at the proper time, as long as the patient uses its built-in
Scientists are increasingly looking at using medication-filled microspheres for targeted drug delivery within the human body. Silicone would
be a particularly good building material for such spheres, as it's
biocompatible, waterproof, and chemically stable. Unfortunately, using
traditional methods, it can't be made into small enough spheres. Now,
however, a new process has allowed for the creation of silicone
microspheres that are about one one-hundredth the size of any previously
