Effect of carboxyl density at the core–shell interface of surface-imprinted magnetic trilayer microspheres on recognition properties of proteins
A novel protein surface-imprinted magnetic trilayer composite microsphere (Fe3O4@HEA@protein-MIPs) was designed and prepared. The objective of this study was to study the effect of carboxyl density at the core–shell interface on recognition performance. The imprinting process was carried out on the surface of Fe3O4@hydroxyethyl acrylate (Fe3O4@HEA) microsphere modified by maleic anhydride (MAH)...

Synthesis of Poly(methacrylic acid)-MnO(OH)2/SiO2 Core-shell and the Corresponding Hollow Microspheres Containing Mn2O3
Poly(methacrylic acid)-MnO(OH)2/SiO2 core-shell microspheres were prepared by the sol-gel hydrolysis of tetraethylorthosilicate
(TEOS) in presence of poly(methacrylic acid)-Mn(II) (PMAA-Mn2+) as
template with ammonium hydroxide anion as the catalyst and n-octadecyltrimethoxysilane (C18TMS) as pore-directing
reagent. The PMAA-Mn2+ core was prepared by incubation of Mn2+ cations with PMAA micro...

Nanofibers with Very Fine Core-Shell Morphology from Anisotropic Micelle of Amphiphilic Crystalline-Coil Block Copolymer
A novel and facile strategy, combining anisotropic
micellization of amphiphilic crystalline-coil copolymer in water and
re-assembly during single spinneret electrospinning, was developed for preparing nanofibers with very fine core-shell structure. Polyvinyl alcohol (PVA) and polyethylene glycol-block-poly(p-dioxanone) (PEG-b-PPDO)
were used as the shell and the crystallizable core layer,
respecti...

[JMCA] Electric Field Induced Structural Color Changes of SiO2@TiO2 Core-Shell Colloidal Suspensions
A new core-shell nano building block of SiO2@TiO2 using high refractive index materials of TiO2 to coat SiO2 colloidal NPs by one step approach was prepared. Through the self-assembly of SiO2@TiO2 core-shell NPs through applied electric field, a suspension of photonic crystals with close packed are formed in propylene carbonate. The reflectance spectrum of the SiO2@TiO2 suspension was investigated...

Narrow-dispersed Crosslinked Core-shell Polymer Microspheres Prepared by Surface-initiated Atom Transfer Radical Polymerization
Grafting of polystyrene with narrowly dispersed polymer microspheres through surface-initiated atom transfer radical polymerization (ATRP) was investigated. Polydivinylbenzene (PDVB) microspheres were prepared by dispersion polymerization with poly(N-vinyl pyrrolidone) (PVP) as stabilizer. The surfaces of PDVB microspheres were chloromethylated by chloromethyl methyl ether in the presence of zinc ...
