Nanotechnology researchers develop 'onion' vesicles for drug delivery

Researchers have shown that a certain kind of dendrimer, a molecule that features tree-like branches, offers a simple way of creating vesicles and tailoring their diameter and thickness. Moreover, these dendrimer-based vesicles self-assemble with concentric layers of membranes, much like an onion.

Viewing plant cells in 3-D (no glasses required)

Focused ion beam-scanning electron microscopy (FIB-SEM) has been used in both materials science and in the study of animal tissue, but has not previously been used in plant imaging. Researchers have modified existing FIB-SEM protocols and optimized these for plant tissue and cellular studies, shedding new light on plant cell architecture.

Nanoparticle thin-films that self-assemble in one minute

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.

Evolution of a bimetallic nanocatalyst

Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal or plant biomass. A multi-national lab collaboration has taken the most detailed look ever at the evolution of platinum/cobalt bimetallic nanoparticles during reactions in oxygen and hydrogen gases.
