We describe the synthesis and characterisation of novel photocatalytic multiphase micro-droplet reactors comprising TiO2 nanosheets dispersed in poly(diallyldimethylammonium) chloride and adenosine 5'-triphosphate or poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl complex coacervates. We demonstrate significant variations in the degree of equilibrium partitioning of small molecule dyes into t...

Using an aqueous two-phase system comprised of dextran and polyethylene glycol, this article describes the stable spatial patterning of sub-microlitre droplets of bacterial suspensions. Microdroplets of different types of bacterial populations are positioned and maintained adjacent to each other without significant dispersion even though the bacteria are in suspension and not surface bound. Sma...

A macrocyclic tetralactam is threaded by a complementary squaraine dye that is flanked by two polyethylene glycol chains to produce a pseudorotaxane complex with favorable near-infrared fluorescence properties. The association thermodynamics and kinetics were measured for a homologous series of squaraines with different N-alkyl substituents at both ends of the dye. The results show that subtle ...

Microstructured porous zinc oxide (ZnO) thin film was developed and demonstrated as an electron selective layer for enhancing light scattering and efficiency in inverted organic photovoltaics. High degree of porosity was induced and controlled in the ZnO layer by incorporation of polyethylene glycol (PEG) organic template. Scanning electron microscopy, contact angle and absorption measurements ...

Phage libraries may display hormones, receptors, antibody fragments, etc., by fusion to phage envelope proteins. This report describes the direct precipitation of phage-Fab-antigen complexes by polyethylene glycol precipitation, resulting in highly selective and efficient recovery of antigen from complex mixtures without nonspecific protein contamination. The method demonstrates efficiency and ...

The synthesis of clickable polysaccharides was achieved by using alkynylated 1,6-anhydro glucopyranose as a monomer and BF3·OEt2 as an effective catalyst. Subsequent click conjugation with polyethylene glycol (PEG) afforded PEG-grafted polysaccharides in nearly quantitative efficiency.

After modification with monomethoxyl-poly(ethylene glycol)-5000, a recombinant intracellular uricase from Bacillus fastidiosus ATCC 29604 showed residual activity of about 65%, a thermo-inactivation half-life >85 h, a circulating half-life about 20 h in rats in vivo, consistent effects of common cations, and consistent optima for reaction temperature and pH. Thus, this uricase can be formulated...

Much interest has been attracted to the magnetic materials with porous structure because of their unique properties and potential applications. In this report, Fe3O4nanoporous particles assembled from small Fe3O4nanoparticles have been prepared by thermal decomposition of iron acetylacetonate in the presence of polyethylene glycol 4000. The size of the spherical nanoporous particles is 100-200 ...
