Nanoparticle News and Research

RSS

In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Scientists unravel physical properties of lung mucus

Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked. Previously unclear was the extent to which such nanoparticles are able to move through the lungs' mucus. Here, the research evidence was contradictory. Scientists could not explain why, in inhaled medication development, drug nanoparticles often simply got stuck in the mucus never making it to their target destination inside the lung cells.

Study describes design and effectiveness of NIR responsive gold nanorods for chemotherapy

Excitement around the potential for targeted nanoparticles (NPs) that can be controlled by stimulus outside of the body for cancer therapy has been growing over the past few years. More specifically, there has been considerable attention around near-infrared (NIR) light as an ideal method to stimulate nanoparticles from outside the body.

Radioactive gold nanoparticle treatment safe and effective in dogs with prostate cancer

Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs.

Sun protection: an interview with Jane Hanrahan

UV radiation is a form of energy being transmitted. Sunlight is main source of UV radiation, although manmade sources also exist, such as the lamps used in sunbeds. At the earth’s surface sunlight consists of approximately 2 percent UV light, 47 percent visible light and 51 percent IR light.

Broad spectrum sunscreens needed to block UVB and UVA

Writing in the latest edition of Australian Prescriber, Associate Professor Jane Hanrahan from the Faculty of Pharmacy, University of Sydney writes that UVB is the cause of sunburn, but UVA can be more damaging to the skin. It is therefore best to use broad spectrum sunscreens that block both wavebands.

Isolating and concentrating cells from whole blood: an interview with Victor Ugaz

There are several reasons for this. One is because analysis involving different kinds of blood cells may require you to be able to separate red blood cells from white blood cells, or plasma from whole blood etc.

Nanoparticles for non-invasive photodynamic therapy of deep cancer

National University of Singapore researchers at the Faculty of Engineering's Department of Bioengineering have discovered a new technology that paves the way for a new safe and non-invasive method of treating deep cancer. Led by Associate Professor Zhang Yong, the team has so far, proven that their technology could inhibit tumour growth and control gene expression in mice. This is a world's first for the use of nanoparticles for non-invasive photodynamic therapy of deep cancer.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Test to identify potentially deadly calcium deposits in tissues and blood vessels

A new test could help identify and treat individuals at risk of developing potentially deadly calcium deposits in their tissues and blood vessels, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology. Heart disease is the number one killer of patients with chronic kidney disease (CKD), and vascular calcification is thought to play a major role.
