Tunable and reversible aggregation of poly(ethylene oxide-st-propylene oxide) grafted gold nanoparticles.
Two amino-terminated amphiphilic copolymers, M600 and M1000, with different ethylene oxide to propylene oxide EO/PO ratios, 1/9 and 19/3, respectively, were coupled by thioctic acid, which allows an excellent affinity with gold surface. Then, amphiphilic thermally responsive gold nanoparticles (AuNPs) were prepared either by ligands exchange on precursor gold nanoparticles or by direct reductio...
متن کاملTunable, Controlled and Reversible Assemblies of poly(ethylene oxide-st-propylene oxide) grafted Gold Nanoparticles
In recent years, assemblies of functionalised gold nanoparticles (AuNPs) have received a growing interest as a route toward hybrid materials with new functionalities. Here, we report on thermally reversible assemblies formed by mixing thermosensitive polymerprotected AuNPs and Pluronic triblock copolymers. Amino-terminated copolymers, poly(EO-st-PO), with different EO/PO ratios were coupled by ...
متن کاملSynthesis and Cytotoxicity Assessment of Gold-coated Magnetic Iron Oxide Nanoparticles
Introduction: One class of magnetic nanoparticles is magnetic iron oxide nanoparticles (MIONs) which has been widely offered due to of their many advantages. Owing to the extensive application of MIONs in biomedicine, before they can be used in vivo, their cytotoxicity have to be investigated. Therefore, there is an urgent need for understanding the potential risks associated with MIONs.Materia...
متن کاملEnantiospecific desorption of R- and S-propylene oxide from a chiral Cu(643) surface.
The creation or preparation of surfaces with chiral structures offers opportunities for enantioselective heterogeneous chemical processing such as catalysis or adsorption. Although such heterogeneous processes may have advantages over their homogeneous counterparts, the development of enantioselective surfaces lags far behind developments in enantioselective homogeneous chemistry. One approach ...
