QUT scientists on the way to sifting out a cure for HIV

... they often formed pin-holes and cracks during the fabrication process, resulting in wasted membranes. "With this in mind we have introduced radical changes to the membrane texture because it is the membrane texture which is crucial to the separation efficiency of the material," he said. "It is scientifica...

Researchers make nanosheets that mimic protein formation

...hemical surface properties," Glotzer said. "In the fabrication of functional nanoscale materials and devices, self-assembly offers substantial advantages over traditional manufacturing approaches, if we can design the building blocks appropriately. This is what we're trying to do." ...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...inary," Dluhy said. "And the nice thing about this fabrication methodology is that it's very easy to implement, it's very cheap and it's very reproducible." Tripp said the technique is so powerful that it has the potential to detect a single virus particle and can also discern virus subtypes and those with mu...

Five new technologies that promise to transform medicine

...s include wave technology to isolate cancer cells, fabrication technology to manufacture customised body parts, and the use of miniature robots to track and destroy infections before they cause disease. The individual and collective impact of these technologies is already present in some aspects of contempora...

Secrets of the sea yield stronger artificial bone

...o work with artificial joints. Their ice-templated fabrication technique also holds promise for many applications...esins. Ultimately, their technique may enable the fabrication of new materials with properties that cannot be achieved by nature or conventional processing techni...

UCSB researchers discover shape matters to macrophages

...ze was the main issue in phagocytosis, and because fabrication of non-spherical particles of controlled dimensions has been difficult. The researchers used macrophages from alveolar (lung sac) rat tissue and developed polystyrene particles of various sizes and shapes as model targets. Mitragotri and Champion us...

UC Berkeley researchers create a biologically-inspired artificial compound eye

...dimensional. So, I started thinking about basing a fabrication system on the developmental stages of insect eyes that I'd learned about as a biophysicist and bioengineer." What he and his team came up with is a low-cost, easy-to-replicate method of creating pinhead-sized polymer resin domes spiked with thousan...

Marine sponge yields nanoscale secrets

...chnological, catalytic route to the nanostructural fabrication of valuable materials. Nature produces silica on a scale of gigatons –?thousands of millions of tons –?thousands-fold more than man can produce, said Morse. "This biosynthesis is remarkable because this nanoscale precision can't be duplicated by man....

Liposome finding implies electrical effect on cell development

... potentially exciting practical application in the fabrication of bionanotubes," he said. Images/video: http://bionanotubes.homestead.com ...
