Drug candidate delivered by plant-virus-based carrier shows promise for triple-negative breast cancer

In a pair of firsts, researchers at Case Western Reserve University and Massachusetts Institute of Technology have shown that the drug candidate phenanthriplatin can be more effective than an approved drug in vivo, and that a plant-virus-based carrier successfully delivers a drug in vivo.

Researchers find way to selectively deliver drugs to placenta without harming fetus

Nearly 10 percent of babies born in the United States are born premature, according to the March of Dimes. The underlying cause of many complications during pregnancy is often a poorly functioning placenta, the organ that nourishes and maintains the fetus.

New nanoparticle approach can deliver antiobesity drugs directly to fat tissue

Researchers at MIT and Brigham and Women's Hospital have developed nanoparticles that can deliver antiobesity drugs directly to fat tissue. Overweight mice treated with these nanoparticles lost 10 percent of their body weight over 25 days, without showing any negative side effects.

New method may help identify small amounts of nanomaterials in environment samples

It is still unclear what the impact is on humans, animals and plants of synthetic nanomaterials released into the environment or used in products. It's very difficult to detect these nanomaterials in the environment since the concentrations are so low and the particles so small. Now the partners in the NanoUmwelt project have developed a method that is capable of identifying even minute amounts of nanomaterials in environmental samples.

ZOTEN nanoparticles can help develop natural immunity against genital herpes

An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers from the University of Illinois at Chicago working with scientists from Germany have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.

Exposure to titanium dioxide nanoparticles increases bacterial infection of HeLa cells

When human cells are exposed to titanium dioxide without the presence of UV light from the sun, the risk for bacterial infection more than doubles. This finding by a Stony Brook University-led research team, published early online in the Journal of Nanobiotechnology, raises concerns about exposure to titanium dioxide, a nanoparticle commonly used in millions of products worldwide ranging from cosmetics to toothpaste, gum, food coloring, and medicines.
