As scientists and engineers build devices at smaller and smaller scales, grasping the dynamics of how materials behave when they are subjected to electrical signals, sound and other manipulations has proven to be beyond the reach of standard scientific techniques.
Even the smallest devices, assembled at the molecular level, need motors and oscillators. UC Riverside researchers think bundling groups of carbon nanotubes together could make an ultra-efficient and accurate nano-oscillator.
Gold nanoparticles, which can turn light into intense heat, are showing significant promise as targeted nanoscale thermal scalpels capable of killing cancer cells without damaging healthy tissue. Two new reports now suggest that gold nanoparticles may also be able to deliver additional therapeutic payloads to provide a simultaneous two-pronged attack on malignant cells.
Modern-day doctors may soon start using smell to detect the early warning signs of different illnesses thanks to technology that replicates - and improves upon - the human olfactory system thanks to tiny bioelectronic sensors.
Researchers have devised a method that could allow them to organize tiny molecular machines on a surface and so build devices that pack in thousands of times as many switching units, for instance, than is possible with a conventional silicon chip.
From snowflakes to the leaves on a tree, objects in nature are made of irregular molecules called fractals. Scientists now have created and captured an image of the largest man-made fractal molecule at the nanoscale.
Researchers from the Delft University of Technology Kavli Institute of Nanoscience have discovered how to use the motors of biological cells in extremely small channels on a chip. Based on this, they built a transport system that uses electrical charges to direct the molecules individually.
The European Space Agency (ESA) is seeking a Commercial Agent Network to market and sell the use of ESA s facilities on the International Space Station (ISS) and related resources and services within the Materials and Processes industrial community.
Scientists have found a way to cork nanoscale test tubes. The goal is a better way to deliver drugs, for example, for cancer treatment. Scientists want to fill the teeny tubes with drugs and inject them into the body, where they will seek diseased or cancerous cells, uncork and spill their therapeutic contents in the right place.
A new tactic in the battle against cardiovascular disease ? employing nanoengineered molecules called nanolipoblockers as frontline infantry against harmful cholesterol ? is showing promise in early laboratory studies at Rutgers, The State University of New Jersey.
Eikos Inc. and the National Renewable Energy Laboratory (NREL) have achieved competitive efficiency in two types of solar cells using carbon nanotube conductive coatings, in a significant step toward developing fully printable solar cells.
