Copper nanomaterials with a cubic shape so perfect that they form neatly aligned stacks when brought together have been created by researchers at KAUST. The cuboid copper nanoclusters, developed by rational design, are a new member of an exotic nanomaterial family that has shown many promising properties but has remained very hard to make.
Scientists from Tokyo Metropolitan University have developed a new method for making ordered arrays of nanoholes in metallic oxide thin films using a range of transition metals. The team used a template to pre-pattern metallic surfaces with an ordered array of dimples before applying electrochemistry to selectively grow an oxide layer with holes. The process makes a wider selection of ordered transition metal nanohole arrays available for new catalysis, filtration, and sensing applications.
At the Institute of Scientific and Industrial Research of Osaka University, researchers have fabricated nanopores in silicon dioxide with a diameter of just 300 nm and encapsulated by electrodes.
A research work published in Nature Communications, involving researchers from the Madrid Institute for Advanced Studies in Nanoscience (IMDEA) and the University of Sevilla, has measured for the first time the electrical conductivity of a single carbon nanotube with spin-crosslinked molecules inside it.
New nanoprobes, which were recently developed by Imperial College London (ICL) and tested in zebrafish, could help identify cancer more precisely and may support the diagnosis and treatment in the days to come.
Northwestern University researchers have, for the first time, created borophane -- atomically thin boron that is stable at standard temperatures and air pressures.
An interdisciplinary research team at Lehigh University has unraveled how functional biomaterials rely upon an interfacial protein layer to transmit signals to living cells concerning their adhesion, proliferation and overall development.
Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early diagnosis is very important. For this purpose, imaging techniques such as magnetic resonance imaging (MRI) are widely used to identify the narrowing or blockage of blood vessels.
Specific, effective, with a non-harmful and reversible action: the identikit of the ultimate biomaterial appears to match with graphene flakes.
Scientists have found a way to control the size of special nanoparticles to optimize their use for both magnetic resonance and near-infrared imaging. Their approach could help surgeons use the same nanoparticles to visualize tumours just before and then during surgery using the two different imaging techniques. Their findings were published in the journal Science and Technology of Advanced Materials.
