Utilizing self-assembly on atomically flat, transparent substrates, a team of scientists has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabrication of optoelectronic devices with molecular precision.
A technique called acoustic force spectroscopy uses standing sound waves in a fluid channel to tug on DNA and other biomolecules in a precise and easily controllable way, revealing information about the molecules' structure and mechanical properties.
Researchers involved in a national effort to develop cancer treatments that harness nanotechnology are recommending pivotal changes in the field because experiments with laboratory animals and efforts based on current assumptions about drug delivery have largely failed to translate into successful clinical results.
With just a tiny tweak, researchers greatly increased the device lifetime of organic light-emitting diodes (OLEDs) that use a recently developed class of molecules to convert electricity into light with the potential for increased efficiency at a lower cost in future displays and lighting.
Scientists have developed a nanotechnology-based delivery system containing a protective cellular pathway inducer that activates the body's natural defense against free radicals efficiently, a development that could control a variety of skin pathologies and disorders.
