Onion-like layers help this efficient new nanoparticle glow.
A new, onion-like nanoparticle could open new frontiers in biomaging, solar energy harvesting and light-based security techniques. When it comes to bioimaging, near-infrared light could be used to activate the light-emitting nanoparticles deep inside the body, providing high-contrast images of areas of interest. In the realm of security, nanoparticle-infused inks could be incorporated into currency designs; such ink would be invisible to the naked eye, but glow blue when hit by a low-energy laser pulse — a trait very difficult for counterfeiters to reproduce.

New Approach to Monitoring Changes in Cellular Structure May Lead to Early Detection of Cancerous Cells.
Collaborative Roswell Park/UB team uses Raman microspectroscopy to monitor drug action in single-cell assay. Researchers have developed a new approach to characterizing and monitoring changes in cellular structure. The new type of single-cell-based assay, developed by researchers at Roswell Park Cancer Institute (RPCI) and the University at Buffalo (UB), may provide a tool for detecting cancerous cells early and monitoring cell-to-cell variations in cancer progression or in response to pharmaceutical drugs.

New technology could expand use of photodynamic therapy.
Photodynamic therapy (PDT) is an effective treatment for easily accessible tumors, such as oral and skin cancer.Doctors have used PDT to treat cancer for decades. Cancer cells absorb the drug, which is delivered to the tumor via the bloodstream or locally. Visible light then is applied to the site, which causes the drug to react with oxygen and creates a burst of free radicals that kill the tumor. Unfortunately, visible light does not penetrate tissue well. Conversely, near-infrared light penetrates tissue well but doesn't activate the drugs efficiently. To solve this problem, some researchers are developing drugs that absorb near-infrared light. This method is limited, however, because stable and efficient near-infrared absorbing photosenzitizers are notoriously difficult to synthesize. The UB-led team took a different approach, which uses the tumor's natural environment to tune the light into the necessary wavelengths.

UB spinoff Nanobiotix looks to bring cancer treatment to market.
Successful intermediate clinical trial in February generates boost in company stock price - and new funding for UB research. "It was an exciting field with a lot of great potential; at this time, it was very new, and everything needed to be done," Levy remembers, "I moved to UB because of Dr. Prasad, who proposed to me to develop my ideas in his lab. What I found there was a great place with diverse expertise in biology, physics, chemistry and medicine. This environment was quite unique 15 years ago, and clearly helped me in developing those concepts."

In a new study, the silicon nanocrystals had no toxic effects in non-human primates
Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study. The findings, published online July 10 in the journal ACS Nano, suggest that the silicon nanocrystals, known as quantum dots, may be a safe tool for diagnostic imaging in humans. The nanocrystals absorb and emit light in the near-infrared part of the spectrum, a quality that makes them ideal for seeing deeper into tissue than traditional fluorescence-based techniques.

New technology could help power portable devices like satellite phones and radios
According to University at Buffalo researchers,super-small particles of silicon react with water to produce hydrogen almost instantaneously. in a series of experiments, the scientists created spherical silicon particles about 10 nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen - a potential source of energy for fuel cells.The reaction didn't require any light, heat or electricity, and also created hydrogen about 150 times faster than similar reactions using silicon particles 100 nanometers wide, and 1,000 times faster than bulk silicon, according to the study. The findings appeared online in Nano Letters on Jan. 14. The scientists were able to verify that the hydrogen they made was relatively pure by testing it successfully in a small fuel cell that powered a fan.

Nanoparticles Glow Through Thick Layer of Tissue
An international research team has created unique photoluminescent nanoparticles that shine clearly through more than 3 centimeters of biological tissue -- a depth that makes them a promising tool for deep-tissue optical bioimaging. Though optical imaging is a robust and inexpensive technique commonly used in biomedical applications, current technologies lack the ability to look deep into tissue, the researchers said. This creates a demand for the development of new approaches that provide high-resolution, high-contrast optical bioimaging that doctors and scientists could use to identify tumors or other anomalies deep beneath the skin. The newly created nanoparticles consist of a nanocrystalline core containing thulium, sodium, ytterbium and fluorine, all encased inside a square, calcium-fluoride shell.
