Vacuum-compatible Pilatus X-ray detector can now track nanoparticles

Microvesicles are smallest cell elements which are present in all body fluids and are different, depending on whether a person is healthy or sick. This could contribute to detecting numerous diseases, such as, e.g., carcinomas, at an early stage, and to treating them more efficiently. The problem is that the diameter of the relevant microvesicles generally lies below 100 nm, which makes them technically detectable, but their exact size and concentration hardly possible to determine. A new device is now to provide the metrological basis for these promising biomarkers.

New polymer nanoparticles can generate heat and kill colorectal cancer cells

Researchers at Wake Forest Baptist Medical Center have modified electrically-conductive polymers, commonly used in solar energy applications, to develop revolutionary polymer nanoparticles (PNs) for a medical application. When the nanoparticles are exposed to infrared light, they generate heat that can be used to kill colorectal cancer cells.

BRIGHTs bind to biomarkers of disease and light up to reveal their location

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

New solar steam method from Rice University

Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics (LANP) is so effective it can even produce steam from icy cold water.

New nanoparticle halts relapsing remitting multiple sclerosis in mouse model

In a breakthrough for nanotechnology and multiple sclerosis, a biodegradable nanoparticle turns out to be the perfect vehicle to stealthily deliver an antigen that tricks the immune system into stopping its attack on myelin and halt a model of relapsing remitting multiple sclerosis (MS) in mice, according to new Northwestern Medicine research.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

WU researchers to study blood-clotting disorders

Researchers at Washington University School of Medicine in St. Louis have received a $9 million grant to investigate blood-clotting disorders. From heart attacks and strokes to uncontrolled bleeding, clotting disorders cause more deaths each year in the United States than all types of cancer combined.

Researchers show how ingesting too much silver can cause argyria

Researchers from Brown University have shown for the first time how ingesting too much silver can cause argyria, a rare condition in which patients' skin turns a striking shade of grayish blue.

Nano-reinforced plastics improve friction resistance of orthodontics

Brackets made from clear plastic polymer used in dental correction orthodontics have produced very good results in recent years, especially in relation to the improved esthetics when compared to metal brackets, but they do present certain problems of wear and tear within the mouth.

Alternate method to precisely tag breast cancer tumors

When surgeons operate to remove a tumor, determining exactly where to cut can be tricky. Ideally, the entire tumor should be removed while leaving a continuous layer of healthy tissue, but current techniques for locating the tumors during surgery are imprecise. Now a multidisciplinary team from the University of California, San Diego, is developing an alternate means of precisely tagging breast cancer tumors for removal or targeted destruction.

Scientists develop new prototype ultra sensitive disease sensor

Scientists have developed a prototype ultra-sensitive sensor that would enable doctors to detect the early stages of diseases and viruses with the naked eye, according to research published today in the journal Nature Nanotechnology.

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.
