New reagent for multiphoton lithography greatly extends available shapes
A new MPL reagent, which its creators dub “protogel”, is allowing researchers to create exciting new 3D microstructures.
Large-Area Low-Cost Gold Nanostructures through Colloidal Nanolithography
Double split-ring resonators with optimized Fano resonances for refractive index sensing could be realised by hole-mask colloidal nanolithography.
Enzymes Dig Channels: Bio-Etching for Nanostructured Surfaces
Enzymatic etching used to build nano- and microscale surface topologies.
Protocells – A Versatile Drug Delivery Platform
A new hybrid nanoarchitecture has been developed to allow the use of protein toxins such as ricin in cancer treatment.
Nuclear Power: Extracting Uranium from Seawater
The combination of high-capacity reusable adsorbents and high-surface-area polyethylene fibers creates a material that can rapidly, selectively and economically extract valuable and precious dissolved metals from water.
Broadband Plasmonic Response of Semiconductor Disks
The plasmonic behavior of touching semiconductor disks shows a highly efficient broadband response in the terahertz regime as predicted by theoretical studies.
Molecular Layer Deposition: building hybrid materials one layer at at time
As the applications of nanotechnology grow more sophisticated, the controlled deposition of exceedingly thin layers of materials becomes of ever growing importance. A well-known technique called atomic layer deposition (ALD) can meet this challenge quite well for the...
Electrochromic Bragg mirror
Researchers report the first example of an electrochromic Bragg mirror based on nanoporous multilayers of nickel oxide and tungsten trioxide nanoparticles.
Slab-nanocrystal nanolasers
Low-threshold nanolasers based on slab-nanocrystals of H-aggregated organic semiconductors are reported by researchers at the Chinese Academy of Sciences.
