Nanoparticles

Researchers have developed a way to treat male infertility by delivering nanoparticles loaded with proteins directly into the testes. In tests in mice, previously infertile animals were soon able to father pups at a similar rate as unaffected mice.

Researchers in India have taken an impressive step forward with efforts to tackle cancer using magnetic nanoparticles, working the technology into a bandage that proved capable of killing skin cancer cells in experiments on mice.

“Trojan horse” approaches use all kinds of trickery to sneak drugs into cancer cells to kill them off, but scientists are putting forward another solution, demonstrating how a new drug-free nanoparticle can do the heavy lifting on its own.

Gold has shown promise in fighting cancer in many studies, and now researchers have found a way to grow gold nanoparticles inside cancer cells within 30 minutes. From there, the gold can help with imaging and even be heated up to kill the tumors.

Adding “two-faced” nanoparticles could improve paints and coatings. With one face that attracts water and another that repels it, the particles arranged themselves in a flat layer on a painted surface and could make for paint with unusual properties.

Although cavities are caused by bacteria, simply killing all of the bacteria in the mouth isn't a good idea, as some of them have beneficial effects. A nanoparticle coating, however, could someday prevent cavities without harming bacteria.

It was just a couple of months ago that we heard about an implantable material that electrically stimulates bone cells, causing them to reproduce. Now, scientists have created a similar substance that utilizes magnetism.

As compared to their incandescent counterparts, LED bulbs are already known for producing a lot of light using relatively little electricity. According to a new study, however, a thin layer of nanoparticles could allow them to perform even better.

Impressive new work has demonstrated a potential way to restore vision in those suffering from degenerative diseases of the retina. A single injection of nanoparticles was found to create a working artificial retina, restoring vision to blind rats.

A new type of ultra-thin film with an incredible ability to change color as it is twisted or bent could one day make its way onto robots to give them chameleon-like skin, or into cash as a means of verifying its authenticity.

Would you buy a cloudy white wine? Probably not, which is why vintners go to great lengths to clarify their product. Soon, they could do so more efficiently than ever, using newly created nanoparticles.

Not all maple syrups are created equal. There are actually over 60 taste categories that syrups fall into, as determined by human taste-testers. Soon, though, a solution containing gold nanoparticles could save those people some work.
