The most efficient colloidal-quantum-dot solar cell ever created will be described in a scientific paper to be published in a print edition of the journal Nature Materials by a team of scientists that includes John Asbury, assistant professor of chemistry at Penn State. Quantum dots are nanoscale semiconductors that capture light and convert it into electrical energy. Because of their small size, the dots can be sprayed onto flexible surfaces, including plastics, enabling the production of solar cells that are less expensive than the existing silicon-based version.

Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers. (more)

High school students and their families will get a chance to see what nanotechnology is all about at Nano Days at Penn State on Saturday, April 4, at the Penn Stater Conference Center Hotel. Designed to showcase two- and four-year nanotechnology-related degree programs offered across Pennsylvania, Nano Days will offer visitors laboratory tours, hands-on activities, presentations and scholarship details. In addition to high school students and their families, the event is also open to teachers, administrators, guidance counselors and college students. (more)

Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch.

A handheld, ultra-portable device that can recognize and immediately report on a wide variety of environmental or medical compounds may eventually be possible, using a method that incorporates a mixture of biologically tagged nanowires onto integrated circuit chips, according to Penn State researchers.

Nanotechnology generally involves manipulating matter at an incredibly small level - that of the nanometer. (A nanometer is about 100,000 times thinner than a sheet of office paper, and a strand of DNA is about 2 nanometers across.) Hybrid fields are emerging at the crossroads of nanotechnology and pharmacology, genetics, aeronautics, and fashion, just to name a few. (more)

A national leader in nanotechnology education and workforce development since 1998, Penn State will receive $5 million over four years from the National Science Foundation to establish a National Center for Nanotechnology Applications and Career Knowledge (NACK). The new center succeeds the NSF Regional Center for Nanofabrication Manufacturing Education, which was housed at Penn State from 2001 to 2008. (more)

A new imaging method for breast cancer has been developed by a team of Penn State researchers. Their research, using encapsulated fluorescent molecules in calcium phosphate nanoparticles and non-toxic near infrared imaging (NIR), appears in the Sept. 19 online issue of ACS Nano. By combining NIR imaging with nanoparticles containing a NIR fluorescing dye, indocyanine green, the researchers were able to detect 5 millimeter diameter breast cancer tumors in a live mouse model over a period of four or more days.

Nanoparticles filled with a drug targeting two genes that trigger melanoma could offer a potential cure for this deadly disease, according to cancer researchers at Penn State's College of Medicine. The treatment, administered through an ultrasound device, demonstrates a safer and more effective way of targeting cancer-causing genes in cancer cells without harming normal tissue. (more)
