The word “nanotechnology” may sound futuristic, but as Russell Mumper, PhD, points out, the future has been around for decades.

“I’m not going to fool anybody by saying that nanotechnology is new,” says Mumper, an internationally recognized leader in applying nanotechnology to applications in pharmaceutical sciences. “ ‘Nanotechnology’ is defined by the National Nanotechnology Initiative as any type of system that has at least one dimension less than a hundred nanometers. That’s a fairly encompassing definition. There are lots of technologies that fit under that.

“For instance, liposomes have been around for more than 40 years, and they are in probably a dozen commercial products, and some of these products were approved a decade ago and meet that definition.”

However, the last ten years have seen a growing recognition of nanotechnology’s potential and an increasing ability to turn that promise into reality. Those factors, Mumper says, have sparked a nanotechnology explosion.

“People are seeing it as the next great revolution after the computer age,” he says.

Mumper is trying to make UNC-Chapel Hill a key player in that revolution. He joined the UNC Eshelman School of Pharmacy in summer 2007 as the John A. McNeill Distinguished Professor and the director of the new Center for Nanotechnology in Drug Delivery. The CNDD, part of a campus-wide nanomedicine initiative at UNC, will bring together scientists to create nano-scale pharmaceutical innovations for therapeutic and diagnostic purposes.

At sizes less than one-ten thousandths of a millimeter, nanoparticles might hold the key to overcoming some of the biggest hurdles in drug delivery, such as solubility, stability, and the need to get an otherwise potent drug inside the cell. However, for nanotechnology to be successfully applied to pharmaceutics, the products must be safe and efficacious, cost effective, and able to be mass manufactured. In the case of the nano-scale liposomal commercial products introduced a decade ago, Mumper says the difficulty and cost involved in making those liposomal drugs have prevented widespread therapeutic and commercial use.

More recently, however, more viable nano-based products have been developed commercially, helping heighten the public’s awareness of the potential of nanotechnology.

“So now people are saying, ‘OK, now we see the promise is becoming a reality in commercial products,’ Mumper says. “These new products derived from nanotechnology are helping people, proven to be safe, and have market sales in the hundreds of millions of dollars. The promise of nanotechnology was always there. However, the reduction to practice was lagging. But now it’s been reduced to practice in many areas of the pharmaceutical sciences, and these products are having visible commercial success. As a result, more money is flowing into research and development, and people are more excited about it.”

“It’s the tip of the iceberg. Part of the plan for the center is to look at the various aspects of nanotechnology and how they merge together to make this a realization.”
