Biophotonics: Light to cure disease

Biophotonics, or photomedicine, is a relatively unknown discipline, though it has existed for years now. You may have even benefited from it without realizing it. Some of the greatest advances of this field can be found in applications for the areas of oncology, dermatology, ophthalmology, surgery and cardiology.

Novel procedure opens door to new and future treatment for pancreatic cancer

Pancreatic cancer-known as the most fatal cancer with no known effective treatment-requires a radical new therapy. A promising approach may come in the form of tiny gold nanoparticles-loaded with a therapeutic agent to kill cancer-in a novel procedure called "nanoembolization," said researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

Houston scientists unveil new technique for growing 3-D cell cultures

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of Houston scientists this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs. The research is reported in Nature Nanotechnology.

Directing gold nanoparticles into nucleus can kill cancer cells

Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can't reach? Scientists at the Georgia Institute of Technology have shown that by directing gold nanoparticles into the nuclei of cancer cells, they can not only prevent them from multiplying, but can kill them where they lurk. The research appeared as a communication in the February 10 edition of the Journal of the American Chemical Society.

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

Nanoparticle-based “chemical nose” sniffs out cancer earlier to improve treatment options

Using a "chemical nose" array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells. It is a tool that could revolutionize cancer detection and treatment, according to Vincent M. Rotello, Ph.D., M.Phil., and D. Joseph Jerry, Ph.D., M.S., the investigators who led the study.

Computer-guided nanoparticle therapy destroys tumors

Gold nanoshells are among the most promising new nanoscale therapeutics being developed to kill tumors, acting as antennas that turn light energy into heat that cooks cancer to death. Now, a multi-institutional research team has shown that polymer-coated gold nanorods one-up their spherical counterparts, with a single dose completely destroying all tumors in a nonhuman animal model of human cancer.
