Monodisperse water-soluble Co and gamma-Fe(2)O(3) nanoparticles have been prepared in a single-step method using stimuli-sensitive polymers.

In this paper, we review the vibrational spectroscopic analyses of the structure and hydrogen bonding of water in the vicinity of various polymers based on research performed by our group. Aqueous solutions of water-soluble polymers have been examined using the contours of O–H stretching in polarized Raman spectra. For water sorbed into polymer thin films, infrared spectroscopy was used and the...

In this work, two water soluble fluorescent non-conjugated polymers have been designed and synthesized.

Boron is required for fiber growth and development in cotton ovules cultured in vitro. Incorporation of [(14)C]glucose by such fiber from supplied UDP-[(14)C]glucose into the hot alkali-insoluble fraction is rapid and linear for about 30 minutes. Incorporation of [(14)C]glucose from such substrate by fibers grown in boron-deficient ovule cultures is much less than in the case with fibers from o...

The synthesis of a series of novel, water-soluble poly(organophosphazenes) prepared via living cationic polymerization is presented. The degradation profiles of the polyphosphazenes prepared are analyzed by GPC, 31P NMR spectroscopy, and UV-Vis spectroscopy in aqueous media and show tunable degradation rates ranging from days to months, adjusted by subtle changes to the chemical structure of th...

A new method of supramolecular polymerization at the water-oil interface is developed. As a demonstration, an oil-soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water-soluble monomer bearing two maleimide end groups are employed. Supramolecular interfacial polymerization can be implemented by a thiol-maleimide click reaction at the water-chloro...

Membranes grafted with water-soluble polymers resist protein adsorption and adhesion to cellular surfaces. Liposomes with surface-grafted polymers therefore find applications in drug delivery. The physicochemical properties of polymer-grafted lipid membranes are reviewed with mean-field and scaling theories from polymer physics. Topics covered are: mushroom-brush transitions, membrane expansion...
