Scientists have discovered a novel cause of glaucoma in an animal model, and related to their findings, are now developing an eye drop aimed at curing the disease. They believe their findings will be important to human glaucoma.
The surface of graphene, a one atom thick sheet of carbon, can be randomly decorated with oxygen to create graphene oxide; a form of graphene that could have a significant impact on the chemical, pharmaceutical and electronic industries. Applied as paint, it could provide an ultra-strong, non-corrosive coating for a wide range of industrial applications.
Misfolded proteins can lead to a variety of diseased states, including Alzheimer's and Parkinson's. Researchers have now developed a method with which one can synthesize hundreds of proteins and analyze their folding properties at once at the single-molecule level.
Scientists have for the first time used photothermal induced resonance (PTIR) to characterize individual plasmonic nanomaterials in order to obtain absorption maps and spectra with nanometer-scale resolution. Nanostructuring of plasmonic materials enables engineering of their resonant optical response and creates new opportunities for applications that benefit from enhanced light-matter interactions, including sensing, photovoltaics, photocatalysis, and therapeutics.
A team of researchers has discovered a way to cool electrons to -228 C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy.
A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. A collaboration of researchers used low energy or 'soft' X-rays to image structures only five nanometers in size. This resolution is the highest ever achieved with X-ray microscopy.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an 'electronic skin' that 'feels' and images small lumps that fingers can miss.
Using a metal-doped graphene junction coupled evanescently to the waveguide, the detector achieves a photoresponsivity exceeding 0.1 A/W together with a nearly uniform response between 1,450 nm and 1,590 nm.
Researchers infused antibody-studded iron nanoparticles into the bloodstream to treat heart attack damage. The combined nanoparticle enabled precise localization of the body's own stem cells to the injured heart muscle.
