Nanoparticles do not penetrate beneath outermost layer of cells when applied to the skin

Ultra-tiny zinc oxide (ZnO) particles with dimensions less than one-ten-millionth of a meter are among the ingredients list of some commercially available sunscreen products, raising concerns about whether the particles may be absorbed beneath the outer layer of skin.

New material emits long-lasting, near-infrared glow after sunlight exposure

Materials that emit visible light after being exposed to sunlight are commonplace and can be found in everything from emergency signage to glow-in-the-dark stickers. But until now, scientists have had little success creating materials that emit light in the near-infrared range, a portion of the spectrum that only can be seen with the aid of night vision devices.

Gold nanoparticles help detect lung cancer in exhaled breath

The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too.

Nanomedicine neither a cure-all nor a potential danger

Is the emerging field of nanomedicine a breathtaking technological revolution that promises remarkable new ways of diagnosing and treating diseases? Or does it portend the release of dangerous nanoparticles, nanorobots or nanoelectronic devices that will wreak havoc in the body? A new review of more than 500 studies on the topic concludes that neither scenario is likely. It appears in ACS' journal Molecular Pharmaceutics.

Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

Researchers explore novel therapeutic approach for thyroid cancer

Some forms of differentiated thyroid cancer (DTC) respond to treatment with radioactive iodine, which is taken up by the thyroid gland, destroying the cancerous cells. However patients with two forms of thyroid cancer, radioiodine-refractory DTC and anaplastic thyroid cancer (ATC), do not benefit from radioiodine therapy, and other treatment options are limited.

Nanoparticles could help increase retention of osteoarthritis drugs in knee cavity

A novel study demonstrates that using nanoparticles to deliver osteoarthritis drugs to the knee joint could help increase the retention of the drug in the knee cavity, and therefore reduce the frequency of injections patients must receive.

Researchers use gold nanorods to distinguish brain tumor from healthy tissue

"It's not brain surgery" is a phrase often uttered to dismiss a job's difficulty, but when the task actually is removing a brain tumor, even the slightest mistake could have serious health consequences. To help surgeons in such high-pressure situations, researchers from Prof. Adam Wax's team at Duke University's Fitzpatrick Institute for Photonics and Biomedical Engineering Department have proposed a way to harness the unique optical properties of gold nanoparticles to clearly distinguish a brain tumor from the healthy, and vital, tissue that surrounds it.
