Nanoparticles may have negative effects on environment and human health
Washington, September 14 (ANI): A new analysis has indicated that the same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health.
The analysis was done by an international team of researchers from the Center for the Environmental Implications of NanoTechnology (CEINT), based at Duke [...]
‘NanoPen’ may revolutionise electronics sector, medical diagnostic tests
Washington, September 3 (ANI): A team of scientists in California have announced the creation of a ‘NanoPen’ that can simplify the method of laying down patterns of nanoparticles-from wires to circuits-for making futuristic electronic devices, medical diagnostic tests, and other much-anticipated nanotech applications.
Writing about their work in ACS’ Nano Letters, Ming Wu and colleagues point [...]
Now, acoustic tweezers to position tiny objects
Washington, Aug 29 (ANI): While it gets quite difficult to manipulate tiny objects like single cells or nanosized beads via relatively large, unwieldy equipment, Penn State engineers have now designed a new system that uses sound as a pair of tiny tweezers that are small enough to place infinitesimal objects on a chip.
While optical tweezers [...]
Lung damage from inhaling nanoparticles sparks off health fears
London, August 19 (ANI): A new study, which analyzed seven Chinese factory workers developing severe lung damage from inhaling nanoparticles, has triggered off debate over the environmental-health effects of nanotechnology.
According to a report in [...]
Natural organic matter plays key role in making mercury toxic to living creatures
Washington, August 19 (ANI): Scientists have found that naturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is toxic to most living creatures.
According to Duke University environmental engineers, this finding is important because it could [...]
Nanoparticles cross blood-brain barrier for ‘brain tumour painting’
Washington, Aug 4 (ANI): In a new research, scientists have succeeded in illuminating brain tumours by injecting fluorescent nanoparticles into the bloodstream that safely cross the blood-brain barrier-an almost impenetrable barrier that protects the brain from infection.
The study by University of Washington researchers revealed that the nanoparticles remained in mouse tumours for up to [...]
