Promising: Nanoparticles reverse bone loss in mice

It started out in test tubes. Scientists introduced engineered 50?nm spherical silica nanoparticles into an artificial environment with a view to seeing whether they might help osteoblasts differentiate and promote bone building while also suppressing the re-absorption of osteoclasts. It worked well. Next they found that could get the nanoparticles to help build bone in young […]

Nanoparticle exposure linked to heart problems

Asbestos was hailed, even many centuries ago, as a material that could be used to create “miraculous” solutions to multiple problems – it was fireproof, it was flexible, it had tremendous insulating properties, it was easy to manipulate, etc. But it had a powerful, long-unacknowledged dark side. It gradually disabled and then killed people who […]

5 news bits – nitric oxide and nanoparticles

The first item is about nitric oxide (NO) used in testing, and the rest are all about using nanoparticles for delivering things into the human body, including NO. It’s astounding that scientists have found nanotechnology so helpful in these kinds of applications. I just hope more research is done on how safe it is to […]

Nanoparticles in contrast agent “see” blood vessels better

Wouldn’t it be nice if doctors didn’t have to use invasive tests such as heart catheterization to tell if any of your arteries are clogged? Heart caths are not fun – and they carry their own set of risks. I’m happy to say they’re working on it. Just saw this report on an NIH-funded study […]

Danger from nanoparticles may depend on length of fibers

I’ve been worrying about potential danger from these guys ever since I first heard about them. Now comes some research indicating strongly that nanoparticles/nanofibers could be deadly to humans who are exposed to them. This particular research shows that it may be the length of the fibers that’s critical to whether they might eventually induce disease. […]

Nanoparticles can damage plant DNA

It’s not good news, but it’s also not unexpected. Recent experiments with adding engineered nanoparticles to plants’ diets determined that the plants started gradually shriveling up and dying. Specifically, the plants being experimented with were radishes and two ryegrass ground covers that grazing animals commonly eat.  Researchers at National Institute of Standards and Technology (NIST) […]

Mouse studies say nanoparticle-delivered drugs can be targeted

Reports are all over the Internet about a recent study using nanoparticles as additions to vaccines that target lymph nodes. The study has found that, at least in mice, these nano-loaded treatments can boost antibody- and immune responses against lethal infections. The Duke University team that did the study says their loaded nanoparticles closely mimic […]
