Nano expert Lisa Friedersdorf from the National Nanotechnology Coordination Office provides information on nanomaterials that have existed throughout history. She also gives additional information on the nanoscale. Part of the “Ask a Scientist” series.
What if scientists could grow elevators to space? Or make phones that last for weeks without a charge? These things could be possible someday with an amazing material like carbon nanotubes. A MIT scientist discusses the curious way researchers create this super-material. Part of the "Science Out Loud" series.
Nano expert Nicole Steinmetz from Case Western Reserve University discusses naturally occurring nanomaterials. Part of the “Ask a Scientist” series.
Nano expert Oliver Brand from Georgia Tech University discusses the difference between nanoscale and atomic scale. Part of the “Ask a Scientist” series.
Nano expert Will Hughes from Boise State University discusses the current and potential uses of nanotechnology in the field of medicine. Part of the “Ask a Scientist” series.
Nano expert Karen Wooley from Texas A&M University discusses how nanotechnology can improve everyday life by enhancing current household products. Part of the “Ask a Scientist” series.
Nano expert Jameson Wetmore from Arizona State University offers tips for managing the potential risks associated with nanotechnology. Part of the “Ask a Scientist” series.
Nano expert Saniya LeBlanc from George Washington University discusses how scientists are able to work with such small particles. Part of the “Ask a Scientist” series.
With support from the National Science Foundation, Liangfang Zhang and his team at UC-San Diego have created a nanosponge to combat drug-resistant infections, such as those caused by Methicillin-resistant Staphylococcus aureus (MRSA). The nanosponge, made from biocompatible, biodegradable polymer nanoparticles, is camouflaged with a red blood cell membrane. It circulates in the bloodstream, absorbing the toxins produced by infection. Once the nanosponges are fully loaded with toxins, they are safely disposed of by the liver. They are designed to work with any type of infection or poison that attacks the cellular membrane. Part of the National Science Foundation Series “Science Nation.”
At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
The world’s population is projected to increase by 2-3 billion over the next 40 years. Already, more than three quarters of a billion people lack access to clean drinking water and 85 percent live in the driest areas of the planet. Those statistics are inspiring chemist Ben Hsiao and his team at Stony Brook University. With support from the National Science Foundation (NSF), the team is hard at work designing nanometer-scale water filters that could soon make clean drinking water available and affordable for even the poorest of the poor. Part of the National Science Foundation Series “Science Nation.”
Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors. Part of the National Science Foundation Series “Science Nation.”
Smart Puppy discusses the characteristics of a nanodot. Part of the “Smart Puppy! and Friends” series.
There’s no shortage of ideas about how to use nanotechnology, but one of the major hurdles is how to manufacture some of the new products on a large scale. With support from the National Science Foundation (NSF), UMass Amherst chemical engineer Jim Watkins and his team are working to make nanotechnology more practical for industrial scale manufacturing. Part of the National Science Foundation Series “Science Nation.”
The Nanosystems Engineering Research Center (NERC) for Advanced Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University is developing technology that will alert someone when air pollution is about to take its toll on their heart and lungs. ASSIST Director Veena Misra and her multidisciplinary team are using nanotechnology to develop small, wearable sensors that monitor a person’s immediate environment, as well as the wearer’s vital signs. Part of the National Science Foundation Series “Science Nation.”
There are only a few procedures that can detect very early signs of cancer. Those that do are often invasive, expensive, and uncomfortable. With support from the National Science Foundation, Vadim Backman of Northwestern University is developing technology that makes detecting cancer earlier. He’s doing it by shedding light on cancer cell development at the nanoscale level.
While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro and nanometer length scales. At those sizes, 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. With support from the National Science Foundation, Brown University mathematician Govind Menon and Johns Hopkins University chemical and biomolecular engineer David Gracias are developing self-assembling 3-D micro and nanostructures which can be used in a number of applications, including medicine.
Josh Landis and Mitch Butler discuss metamaterials, a type of nanotechnology. These materials can theoretically make objects disappear from plain sight. This cloaking technology has a wide range of applications and could forever change the view of the world. Part of the Fast Draw Series.
The cloning of Dolly the sheep can trace its origins all the way back to Charles Darwin's trip to the Galapagos Islands in the 1800s. Darwin's evidence for evolution was overwhelming, but scientists still didn't know how traits passed from parent to offspring. As microscopes improved, scientists were able to see cells divide and eventually discovered the genes that make up DNA. This, along with other technological advances, has opened up an exciting new area of scientific study: nanotechnology.
