Unique chiral molecules that are optically active whilst presenting magnetic order have been prepared by a team from Barcelona, Spain. The synergy which may take place between optical activity and magnetic fields is attracting interest, and Jaume Veciana and his team are investigating new molecular materials that combine magnetic and chiral properties whilst exhibiting synergistic effects like magneto-chiral dichroism. These chiral molecules are the first materials of their kind, and could exhibit magneto-chiral dichroism under sensitive experimental conditions
US researchers led by Peter Gascoyne at the University of Texas present a programmable system of accurately titrating, moving and mixing microfluidic droplets of any composition using dielectrophoresis (DEP). In DEP movement of droplets depends only on dielectric properties and is independent of polarity or electrical conductivity. They have coupled this technology to control software creating a general-purpose device which could offer an off-the-shelf solution to almost any fluid-based analysis or microscale-synthesis problem.
Renato Zenobi and co-workers in Zurich and Estonia have developed matrix-assisted laser desorption/ionization (MALDI) methods that are softer, avoiding the high-vacuum conditions which can damage molecules of biological interest by undoing reactions relevant in proteomics, eg phosphorylation. They interface their new method to liquid chromatography (LC), which should allow analysis of complex samples from environmental, forensic and pharmaceutical analysis, and medical diagnostics.
Oxford researchers describe single walled carbon nanotubes (SWNTs) as the world's smallest test tubes with potential applications in the electronic, engineering and medical sciences. A novel procedure is presented for the filling of SWNTs with alkali metal hydroxides. The filling is washed out and the tubules re-filled with clusters and molecules under mild conditions. They believe that this methodology will be widely applicable for the filling of SWNTs with a variety of chemicals and materials.
