Drug delivery
-
It slices, it dices, it's super strong and conductive, and now an ultra-pure form of ‘wonder material’ graphene has been inhaled during a human trial without affecting lung or cardiovascular function, opening the door to a novel drug delivery mode.
-
No matter how important something is, too much of anything is bad for you. Scientists have now put that principle to work to kill cancer, with a new drug that causes calcium to build up and choke the tumor to death.

Nobody likes having to get needles on a frequent basis, or even having to take multiple medications orally throughout the day. A wearable patch could help, by painlessly administering different drugs through the skin when triggered by a smartphone.
-
Peptide therapeutics – like insulin – are typically restricted to administration by invasive injection. Now, researchers have reached a "major milestone", creating an oral peptide that could revolutionize how disease treatment is delivered.
-
Managing diabetes usually involves regular shots, but soon patients might only need injections a few times a year. Stanford has developed a hydrogel-based delivery system that slowly releases drugs over months to control diabetes and even weight.
-
In what will soon be commonplace in drug research, scientists have used an artificial-intelligence algorithmic program to identify a compound, currently used in antimalarial treatment, that can effectively reverse the bone deterioration of osteoporosis.
-
Nobody likes getting needles, but unfortunately there are some medications that can only be administered via injection. That could be about to change, however, thanks to the invention of a suction cup that you stick in your mouth.
-
While we've heard about a number of drug-dispensing medical implants, most of them have the same drawback – they end up getting covered in scar tissue. An experimental new one avoids that problem by changing shape as the tissue starts to form.
-
Round pills are easier to swallow, but that doesn’t offer much control in how they release their drug payload. Max Planck scientists have now developed a model for designing complex 3D-printable pill shapes that release drugs in a specific way.
-
Getting young children or the elderly to take medications, especially if they're yucky-tasting syrups, large tablets, or – worse – injections, can be tricky. Researchers have developed an oral film that offers painless, hassle-free drug delivery.
-
A natural arms race, usually between predator and prey, is one of the most fascinating phenomena in evolutionary biology. But if humans don't find a way to get ahead in our fight with bacteria, we may be dealing with 10 million deaths a year by 2050.

Researchers have taken another step forward in medical micro-robotics, designing a tiny sound-propelled bot with a unique design that mimics natural swimmers like bacteria. It can quickly move around the body to deliver drugs where they're needed.
