Researchers have succeeded in producing short chains and rings of gold nanoparticles with unprecedented precision. They used a special kind of nanoparticles with a well-defined structure and linked them together with molecular bridges.
When a baseball pitcher uncorks a nasty curveball, the spinning motion of the ball forces air to flow around it at different speeds, causing the ball to 'break' in one direction. The physics behind this kind of deflection also work at smaller scales.
Researchers are developing tiny, sophisticated technological and biological machines enabling non-invasive, selective therapies. Their creations include genetically modified cells that can be activated via brain waves, and swarms of microrobots that facilitate highly precise application of drugs.
Researchers developed a hybrid nanosensor incorporating magnetic resonance and fluorescence. Lab testing of milk showed the detector could sense varying concentrations of a pathogenic strain of E. coli known as O157:H7 in less than an hour.
Scientists have created a new method to help researchers discover how much the virus's size matters. By mutating a single amino acid in a bacterial virus, the team drastically changed the size of its protein coating, or capsid.
An international team of researchers has invented a method to control the formation of defects called 'shear bands' in metals manufacturing processes and discovered microscopic details of how the defects are created.
Researchers have succeeded in linking graphene with another important chemical group, the porphyrins. These new hybrid structures could also be used in the field of molecular electronics, catalysis or even as sensors.
