[Materials Chemistry and Physics] Controlled growth of metal nanoparticles on amino-functionalized polystyrene microspheres and their application in surface-enhanced Raman spectroscopy
This paper describes the preparation of hybrid materials of metallic nanoparticles (NPs) coated amino-terminated polystyrene (PS-NH2) microspheres by seed-mediated growth technique, and their application in surface-enhanced Raman spectroscopy (SERS). In our approaches, monodisperse PS microspheres are firstly prepared using dispersion polymerization with a subsequent nitration and amination to ach...

Sn-doped V2O5 film with enhanced lithium storage performance. Journal of Physical Chemistry C, 2013, DOI: 10.1021/jp406927m
Homogeneous
Sn-doped V2O5 sol was prepared by sol-gel method with H2O2,
V2O5, and SnCl4?5H2O
as precursors and the films were fabricated by drop-casting, drying at ambient,
and then annealing at 450 °C
in air for 2 hours. X-ray photoelectron spectroscopy (XPS) reveals that the
Sn-doped V2O5 film contains 10% V4+, likely compensates
with the
accommodation of Sn4+ ions. Electrochemical and li...

Hematite Nanostructures Synthesized by Silk Fibroin-Assisted Hydrothermal Method. Journal of Materials Chemistry B, 2013, 1(2): 213-220
A green, simple and economical route based on an efficient Bombyx mori silk fibroin assisted hydrothermal process has been developed to synthesize monodisperse hematite (alpha-Fe2O3) nanostructures with fine shape control. The effects of reaction time and silk fibroin concentration on the morphology of alpha-Fe2O3 have been investigated systematically. Several morphologies including quasi-nanocube...

A Hierarchical Adsorption Material by Incorporating Mesoporous Carbon into Macroporous Chitosan Membrane. Journal of Materials Chemistry, 2012, 22(24): 11908-11911
An easy and practical method is adopted to assemble mesoporous carbon particles into a macroporous chitosan membrane to form hierarchical adsorption membranes for water treatment. The membrane showed both good static and dynamic adsorption properties on model dye fuchsin, which implies its great potential for decontamination in flowing systems.

Synthesis of three-arm poly(ethylene glycol) by combination of controlled anionicpolymerization and ‘click’ chemistry
Poly(ethylene glycol) (PEG) is an important water-soluble polymer, which is widely used in the biomedical field because
of its good biodegradability, biocompatibility and permeability. It is usually synthesized by anionic polymerization of
ethylene oxide but side reactions lead to the formation of some oligomers. High molecular weight PEG can be obtained,
however, through coordinated anionic po...

Journal of Materials Chemistry 2011: Dendrimer modified magnetic iron oxide nanoparticle/DNA/PEI ternary magnetoplexes: a novel strategy for magnetofection
As a powerful technology to enhance the efficiency of gene delivery, magnetofection has attracted considerable attention in the past decade. In this work, we introduced 6 generation of PAMAM dendrimer modified superparamagnetic nanoparticles (DMSPION-G6) to PEI/DNA polyplexes by a two-step process and enhanced the transfection efficiency of PEI with the help of a magnetic field. We prepared DMSPIO...

Self-assembly of small molecules: An approach combining electrostatic self-assembly technology with host-guest chemistry
A fluorescence probe study, surface tension and dye solubilization tests indicate that the water-soluble calixarene, 5,11,17,23,29,35,41,47-octosulfonato-49,50,51,52,53,54,55,56-octododecyloxycalix[8]arene (1(8)-C-12) acts as a "unimolecular'' micelle in water. By forming guest-host-type complexes with 1(8)-C-12, lipophilic dyes, such as methyl yellow (MY), p-hydroxyazobenzene (HAB) and 1-(p-...

Galactosylated N-2-Hydroxypropyl Methacrylamide- b- N-3-Guanidinopropyl Methacrylamide Block Copolymers as Hepatocyte- Targeting Gene Carriers. Bioconjugate Chemistry, 2011, 22 (8), pp 1503–1512
As alternatives of viral and cationic lipid gene carriers, cationic polymer-based vectors may provide flexible chemistry for the attachment of targeting moieties. In this report, galactosylated N-2-hydroxypropyl methacrylamide-b-N-3-guanidinopropyl methacrylamide block copolymers (galactosylated HPMA-b-GPMA block copolymers, or abbreviated as GHG) were prepared in order to develop hepatocyte targe...

Synthesis of ABCD 4-Miktoarm star-shaped quarterpolymers by combination of the click chemistry with multiple polymerization mechanism.
Well-defined ABCD 4-Miktoarm star-shaped quarterpolymers of [poly(styrene)-poly(tert-butyl acrylate)-poly(ethylene oxide)-poly(isoprene)] [star(PS-PtBAPEO-PI)] were successfully synthesized by the combination of the ‘‘click’’ chemistry and multiple polymerization mechanism. First, the poly(styryl)lithium (PSLiþ) and the polyisoprene)lithium (PILiþ) were capped...
