New pod cast explores how viruses produce eco-friendly batteries
WASHINGTON, DC—Viruses are notorious villains. They cause serious human
diseases like AIDS, polio, and influenza, and can lead to system crashes
and data loss in computers.
A new podcast explores how nanotechnology researcher Angela Belcher, from
Massachusetts Institute of Technology (MIT), is working with viruses to
make them do good things. By exploiting a virus’s ability to replicate
rapidly and combine with semiconductor and electronic materials, she is
coaxing them to grow and self-assemble nanomaterials into a functional
electronic device. Through this marriage of nanotechnology with green
chemistry, Belcher and her team are working toward building faster,
better, cheaper and environmentally-friendly transistors, batteries, solar
cells, diagnostic materials for detecting cancer, and semiconductors for
use in modern electrical devices—everything from computers to cell phones.
Unlike traditional semiconductor or battery manufacturing which requires
expensive and toxic chemicals, Belcher’s nanofactories generate little
waste, grow at room temperature, and promise to be inexpensive and largely
biodegradable.
Does all this sound too good to be true" Judge for yourself. Listen to an
interview with Dr. Belcher, a 2004 winner of a MacArthur Foundation
“Genius Award.” It is second in an exciting new series of podcasts called
Trips to the NanoFrontier. These podcasts are available online at
www.penmedia.org/podcast, or directly from Apple’s iTunes music store.
These podcasts and a recent publication, NanoFrontiers: Visions for the
Future (www.nanotechproject.org/114), are written by freelance science
writer Karen F. Schmidt. Both focus on nanotechnology’s ability to address
the energy crisis, the need for better medical treatments, and the demand
for clean water. They are based on a two-day NanoFrontiers forecasting
workshop held in February 2006, sponsored by the National Science
Foundation (NSF), National Institutes of Health (NIH), and the Project on
Emerging Nanotechnologies, which is an initiative of the Woodrow Wilson
International Center for Scholars and The Pew Charitable Trusts.
“Nanotechnology is the future. In 2006 alone, governments, corporations,
and venture capitalists spent $12 billion on nanotechnology research and
development worldwide. Nanotechnology promises to change just about
everything—our medical care, energy sources, communications and food. It
is leading us to what many in government and industry are calling ‘The
Next Industrial Revolution.’ Society needs to prepare now for how to
exploit and harness its potential, especially to ensure that
nanotechnology makes possible a greener, more sustainable tomorrow,” said
David Rejeski, director of the Project on Emerging Nanotechnologies at the
Wilson Center.
“Dr. Belcher’s research with viruses, proteins and yeast offers hope for
new, ground-breaking solutions to the world’s energy problems. It holds
out the prospect of using nanotechnology in a variety of ways, ranging
from improving the efficiency of production, storage, and transmission of
energy to overcoming many of the obstacles to a hydrogen-based
transportation system based on fuel-cell powered cars and trucks,”
according to Rejeski.
About Nanotechnology
Nanotechnology entails the measurement, prediction and construction of
materials on the scale of atoms and molecules. A nanometer is
one-billionth of a meter, and nanotechnology typically deals with
particles and structures larger than 1 nanometer, but smaller than 100
nanometers. To put this into perspective, the width of a human hair is
approximately 80,000 nanometers. In 2014, Lux Research estimates that $2.6
trillion in manufactured goods will incorporate nanotech, or about 15
percent of total global output.
The Project on Emerging Nanotechnologies is an initiative launched by the
Woodrow Wilson International Center for Scholars and The Pew Charitable
Trusts in 2005. It is dedicated to helping business, government and the
public anticipate and manage possible health and environmental
implications of nanotechnology. For more information about the project,
