- Critical role of surface hydration on the dynamics of serum adsorption studied with monoethylene glycol adlayers on gold
-
The dynamics of serum adsorption on bare and monoethylene glycol adlayer-modified gold surfaces is investigated using acoustic wave physics. Hydration experiments support the pivotal role ascribed to water in the antifouling of surfaces. Behavioural discr

On and off: Ester hydrolysis catalyzed by a ZnII-coordinated β-cyclodextrin dimer can be switched on and off using light in the presence of gold nanoparticles with azobenzene units attatched to their surfaces. Under visible light, the azobenzene units are trans and bind tightly to the dimer, thus leading to reduced catalysis. Under UV light, the azobenzene units are cis and bind loosely to the dimer, thus allowing substrates to bind and hydrolysis to occur. Copyright

- Nanoparticles and Method to Control Nanoparticle Spacing
-
Disclosed herein are novel nanoparticles, particularly metal nanoparticles, such as gold nanoparticles. According to one embodiment of a method disclosed herein nanoparticles are functionalized via ligand exchange reactions. Also disclosed is a method for controlling nanoparticle spacing to produce nanoparticle arrays having defined spacing. Such nanoparticles and arrays thereof are particularly useful in nanoelectronics, nanophotonics, catalysis, sensors, and biotaggents.
