A newly discovered repulsive quantum mechanical force could be useful for nanotech applications by enabling a type of quantum levitation.
Researchers have used slot waveguides to condense light energy to scales as small as 60 nm allowing them to trap 75-nm polystyrene nanoparticles and DNA molecules and transport them optically.
An open-access review article describes how a layer of nanoparticles of different sizes, compositions, and shapes enhances the efficiency of thin-film solar cells.
The synthesis and characterization of molecules called cycloparaphenylenes could provide nanotech with an efficient way of producing armchair carbon nanotubes of pre-determined diameter.
DNA nanotech continues to improve the devices it produces as Oxford University scientists fix several shortcomings seen in earlier versions of bipedal DNA molecular walkers.
Nanotech could make possible the controlled release within the patient of up to four different drugs by irradiation with different wavelengths of near-infrared radiation.
The answers of 151 thinkers and visionaries to the Edge Annual question for 2009 have been posted. The question: “WHAT WILL CHANGE EVERYTHING?” As phrased by John Brockman, Editor and Publisher, “What game-changing scientific ideas and developments do you expect to live to see?” In his answer, nanotechnology pioneer Eric Drexler points to a role… Continue reading Will realization of the seriousness of climate change push the development of molecular nanotechnology?
Researchers have been able to attach gold nanoparticles to DNA tiles and, by varying the size of the nanoparticles and the presence of DNA stem loops on some tiles, have been able to control the formation from the DNA tiles of various three dimensional DNA nanotubes.
Scientists have now revealed the working mechanism of one of the most powerful molecular motors known to biology.
Research on the interactions between carbon nanotubes and neurons shows that electrical phenomena in nanotubes may lead to engineering interactions between nanomaterials and neurons.
