Engineers
are developing new and innovative ways of coating medical materials
with nano-sized particles of silver, an element that has long been known
for its antimicrobial properties. However, a recent paper from the
University of Notre Dame highlights the fact that a vast majority of
bacteria are actually neutral, or even beneficial. Overuse of nanosilver
might harm their useful functions in daily life, the paper reports.

The
U.S. government has issued its initial draft guidelines on the use of
nanotechnology, particularly nanoparticles, in food and cosmetic
products. These recommendations, intended to help guarantee consumer
safety within these two industries, do not extend to the other products
that fall under Food and Drug Administration oversights, such as drugs
and medical devices.

According
to recent first-of-its-kind research results, a dose of carbon
nanotubes can more than double the growth rate of plant cell cultures.
Previous work at the University of Arkansas showed that multi-walled
carbon nanotubes can penetrate the thick coatings of seeds. It turns out
they can also stimulate germination and growth in plant cell cultures.

The percentage of electronic waste occupying our landfills has grown at an alarming rate over the last decade, giving rise to concerns about the toxicity of components used in consumer electronics. Researchers at the University of Florida are looking for ways to minimize environmental hazards associated with a material likely to play an increasingly important role in the manufacture of these goods in the future.

A project from a team of researchers from Imperial College London, the University of Manchester, and Durham University beat more than 2,000 other proposals to receive funding from the Bill and Melinda Gates Foundation to develop a prototype system for recovering drinkable water and harvesting hydrogen energy from human faecal waste.

Using high-precision microscopy and X-ray scattering
techniques, University of Oregon researchers have gained eye-opening
insights
into the process of applying green chemistry to nanotechnology that
results in
high yields, improves efficiency, and dramatically reduces waste and
potential
negative exposure to human health or the environment.

Amalgams,
which are alloys of mercury and other metals, have been used for over
2,500 years in the production of jewelry and for the extraction of
metals like silver and gold in mining operations. These days, the
inverse process is of greater interest: the removal of mercury from
wastewater by amalgamation with precious metals in the form of
nanoparticles.

Researchers
at the U.S. Department of Energy’s Savannah River National Laboratory
have successfully shown that they can replace useful little particles of
monosodium titanate (MST) with even tinier nano-sized particles, making
them even more useful for a variety of applications.

Researchers
at the Swiss Federal Laboratories for Materials Science and Technology
have revealed that carbon nanotubes can inhibit the growth of green
algae by reducing the amount of space and light supplied to the plant.
But the nanomaterial, they say, does not affect the plant lethally.
