Researchers at the University of Illinois have developed a technique for fabricating three-dimensional, single-crystalline silicon structures from thin films by coupling photolithography and a self-folding process driven by capillary interactions. This is a completely different approach to making three-dimensional structures.
Researchers at the Institute of Bioengineering and Nanotechnology (IBN), A*STAR, in Singapore, have developed a new protocol for the synthesis of tiny metal and semiconductor crystals that are a few nanometers in size. The efficiency and structural control provided by this method could revolutionize the production of nanocrystals and their hybrids, which have diverse applications in medicine, electronics and energy.
Scientists from the MESA+ Institute for Nanotechnology of the University of Twente and the FOM Foundation have succeeded in transferring magnetic information directly into a semiconductor. For the first time, this is achieved at room temperature. This breakthrough brings the development of a more energy efficient form of electronics, so-called ‘spintronics’ within reach.
A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles. The researchers have learned how to create nanowires with layers of different materials that are sharply defined at the atomic level, which is a critical requirement for making efficient transistors out of the structures.
A lot of the scientific knowledge in chemistry and biology comes from experiments on ensembles of molecules by which a vast number of duplicate behaviors are investigated and averaged responses are recorded. Researchers have now, for the first time, demonstrated direct and amplification-free single molecule detection of biomolecules in sub-nanolitre droplets through application of Cylindrical Illumination Confocal Spectroscopy (CICS) and droplet confinement within a retractable microfluidic constriction.
