RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterials (10/31/2014)

RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterialsSuccessful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Here we leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further advancement in the field of cryopreservation. ...> Full Article


Imaging electric charge propagating along microbial nanowires (10/30/2014)

Imaging electric charge propagating along microbial nanowiresUMass Amherst physicists working with Derek Lovley and colleagues report in the current issue of Nature Nanotechnology that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive man-made material. ...> Full Article


Crystallizing the DNA nanotechnology dream (10/30/2014)

For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features -- a design quest just fulfilled by a team at Harvard's Wyss Institute for Biologically Inspired Engineering. The team built 32 DNA crystals with precisely-defined depth and an assortment of sophisticated three-dimensional features, an advance reported in Nature Chemistry. ...> Full Article

Special microscope captures defects in nanotubesUniversity of Oregon chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. ...> Full Article


Nanoparticle technology triples the production of biogas (10/28/2014)

Researchers of the Catalan Institute of Nanoscience and Nanotechnology, a Severo Ochoa Centre of Excellence, and the Universitat AutÚnoma de Barcelona have developed the new BiogŗsPlus, a technology which allows increasing the production of biogas by 200 percent with a controlled introduction of iron oxide nanoparticles to the process of organic waste treatment. ...> Full Article


Could I squeeze by you? (10/27/2014)

Scientists at the US Department of Energy's Ames Laboratory have developed deeper understanding of the ideal design for mesoporous nanoparticles used in catalytic reactions, such as hydrocarbon conversion to biofuels. The research will help determine the optimal diameter of channels within the nanoparticles to maximize catalytic output. ...> Full Article


Charged graphene gives DNA a stage to perform molecular gymnastics (10/26/2014)

Charged graphene gives DNA a stage to perform molecular gymnasticsWhen Illinois researchers investigated a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics. The researchers found that a positive charge applied to a graphene nanopore speeds up DNA movement, while a negative charge stops the DNA in its tracks. However, the DNA seemed to dance across the graphene surface, pirouetting into sequence-specific shapes they had never seen. ...> Full Article

All that glitters is... slimy? Gold nanoparticles measure the stickiness of snot (10/21/2014)

Researchers at the University of North Carolina at Chapel Hill have developed a way to use gold nanoparticles and light to measure the stickiness of mucus in the airways. Their research, being presented at Frontiers in Optics, could help doctors better monitor and treat lung diseases such as cystic fibrosis and chronic obstructive pulmonary disease. ...> Full Article


Drug-infused nanoparticle is right for sore eyes (10/20/2014)

Drug-infused nanoparticle is right for sore eyesFor the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have developed a topical solution containing nanoparticles that will combat dry eye syndrome with only one application a week. ...> Full Article

Nanoparticles break the symmetry of light (10/18/2014)

Nanoparticles break the symmetry of lightIf a particle emits light into one direction, it usually emits just as much light into the opposite direction. By coupling gold particles to glass fibers, scientists from the Vienna University of Technology have succeeded in breaking this symmetry. This turns the gold particle into a switch which can direct light into two different directions in a glass fiber cable. ...> Full Article
