Conventional tests for Alzheimer’s disease don't provide information about what stage it's at. Now, viewing pathological protein clumps with atomic-force microscopy may help doctors not just detect the disease but determine how far it has progressed.

Researchers tricked glioblastoma cancer cells in mice into taking up iron-filled carbon nanotubes. They then shredded those cells by spinning the tubes using magnetic force. The technique has the researchers hopeful for a similar result in humans.

Australian scientists have designed a new capsule that could mean diabetics might one day swallow their insulin instead of injecting it. The design also has potential uses in delivering other protein drugs, such as antibiotics and cancer treatments.

A new study has demonstrated how nanoparticles can be used as a type of mechanical drug inside cells to impair function and cause their demise, which could be used to target cancer while leaving healthy cells unharmed.

In future, microscopic robots could help heal us. While some of these have been capable of manipulating individual cells, researchers at the University of Toronto have developed a new way to get nanobots inside cells, and precisely control them once they’re in there.

Mostly known for its lustrous fleece and predilection for vigorous spitting, the humble alpaca may soon be more famous for its novel immune system. A study has discovered that the animals produce a unique nanobody that could be recruited into a new treatment for cancer.

​When a clot blocks a blood vessel in the heart, a heart attack is the unfortunate result. Frequently, surgery is required in order to remove that clot. Thanks to an experimental new drug-delivery system, however, that approach may become increasingly unnecessary.

​It's never a good thing when donated human blood – or even the blood in our bodies – is infected with bacteria. Scientists at the University of California San Diego, however, are developing a means of removing such blood-borne microbes using tiny ultrasound-powered robots.

Most medical micro-robots are limited to one method of movement and might not handle complex terrain. Now, a team from the Max Planck Institute for Intelligent Systems has developed a “millirobot” that can walk, crawl, jump, climb, roll, swim and carry loads like a microrobotic Mario.

The latest nanoparticle innovation, driven by advanced computer modeling technologies, targets a broad range of devastating viruses and not only binds to them, but destroys them as well.

​It’s a classic movie trope, distract the guards while our hero sneaks past. A team of researchers at the University of Michigan has deployed the same tactic to reduce inflammation in the body, by using nanoparticles that distract immune cells from negatively inflaming an injury site.

​In what they are calling a world first, nanoengineers have delivered tiny drug-bearing motors into the stomachs of mice where the devices moved around via bubble propulsion, which changed the pH of the stomach to allow the successful dispatch of bug-clobbering antibiotics.
