Controlled ionic condensation at the surface of a native extremophile membrane
Sonia Antoranz Contera, Kislon Voïtchovsky and John F. Ryan,
Nanoscale, 2010, 2, 222
DOI: 10.1039/b9nr00248k Enhanced HTML article available
We investigate ionic effects at the surface of a highly charged extremophile membrane assembled into a 2D crystal. Using amplitude-modulation atomic force microscopy in solution, we obtained sub-molecular resolution images of ion-induced surface restructuring of the membrane.
Preparation, characterization and applications of low-molecular-weight alginate–oligochitosan nanocapsules
Ting Wang and Nongyue He,
Nanoscale, 2010, 2, 230
DOI: 10.1039/b9nr00125e Enhanced HTML article available
In this work, nanocapsules are made from a type of W/O microemulsion system with low-molecular-weight alginate and oligochitosan. The particles possess excellent biocompatibility and good biodegradability.
Metal sulfide nanoparticles synthesized via enzyme treatment of biopolymer stabilized nanosuspensions
Yi-Yeoun Kim and Dominic Walsh,
Nanoscale, 2010, 2, 240
DOI: 10.1039/b9nr00194h Enhanced HTML article available
Nanoparticles of photonic Cu, Ag and Cd sulfides were synthesized by a general novel green synthetic route using the biopolymer dextran at high molecular weight or as crosslinked beads. The enzyme dextranase released the nanoparticles, resulting materials ranged in size from 9–50 nm depending on conditions. UV–vis showed excellent absorption characteristics and the possible mechanisms of this novel biopolymer stabilisation of metal sulfides are discussed.

DOI: 10.1039/b9nr00118b
Nanocomposites which integrate a certain amount of Cr and/or Al nanoparticles with a nanocrystalline metal matrix are oxidation-resistant during oxidation at high temperatures, because of the combined nanosize effects of the particles and metal-matrix grains on the promoted formation of a protective scale of chromia or alumina.
