A new study found that the shape of nanoparticles can enhance drug targeting. According to this study, rod-shaped nanoparticles - or nanorods - as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.
Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide.
The research team demonstrated a novel method to epitaxially synthesize structurally and compositionally homogeneous and spatially uniform ternary InAsyP1-y nanowire on Si at wafer-scale using metal-organic chemical vapor deposition (MOCVD). The high quality of the nanowires is reflected in the remarkably narrow PL and X-ray peak width and extremely low ideality factor in the InAsyP1-y nanowire/Si diode.
Researchers report the design and fabrication of the smallest optical device, capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context.
Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement is an important field of study as the presence of knots affects its physical properties, for instance the resistence to traction.
Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in. Atoms on iron-oxide surfaces behave in a similar way: Only with the right molecular partner do they dance across the surface. Scientists have now filmed the atoms, proving that carbon monoxide is the partner responsible for the quick motion.
Scientists have been able to measure weak forces with sensitivity 50 times higher than what has been achieved to date. This significant improvement represents a turning point in measuring very weak forces and opens the door for magnetic resonance imaging at the molecular scale.
This report on Regional, State, and Local Initiatives in Nanotechnology is the result of a workshop convened 1-2 May 2012 in Portland, Oregon, by the Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council.
An 'artificial cricket hair' used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals - they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility of the tiny hair's supports has made it possible to boost the signal-to-noise ratio by a factor of 25.
CEA-Leti will present recent advances and a preview of future developments in micro- and nanotechnologies, followed by workshops on key technical fields, during Leti Innovation Days, June 25-28, on the MINATEC campus.
