Nanoparticle probes are destined for major new role in medical diagnostics and drug delivery

The emerging miniaturized world known as nanomedicine integrates technology, biology and medicine using tools and materials constructed from molecular- and atomic-sized particles too small to seen with a conventional laboratory microscope. Shuming Nie, PhD, professor of biomedical engineering at Emory University and the Georgia Institute of Technology, and director of cancer nanotechnology at Emory's Winship Cancer Institute, will highlight exciting technological breakthroughs in nanomedicine at the annual meeting of the American Association for the Advancement of Science (AAAS) in Seattle. Dr. Nie's talk on "Bioconjugated Nanoparticles for Personalized Medicine: Molecular Imaging, Profiling and Drug Targeting" will be part of a two-day Nanotechnology Seminar at the meeting.

The science of nanotechnology is rapidly moving from its early beginnings in electronics, computers and telecommunications into the expanding field of biomedical nanotechnology. Dr. Nie has been a leader in the nanomedicine field, and has developed semiconductor nanoparticles called quantum dots, which can be bound to particular genes and proteins and used as markers for molecular diagnostics and drug delivery.

"Biomedical nanotechnology is leading to major advances in molecular diagnostics, therapeutics, molecular biology and bioengineering," Dr. Nie says. "Scientists have begun to develop functional nanoparticles that are linked to biological molecules such as peptides, proteins and DNA."

By virtue of their miniature size nanoparticles assume special properties that distinguish them from larger particles, including the ability to emit light in different colors and to act as fluorescent tags. This makes them highly suitable as contrast agents for magnetic resonance imaging (MRI), positron emission tomography (PET) or as fluorescent tracers in optical microscopy. They also may be useful as structural scaffold in tissue engineering.
