Hydroxystearic acid (HSA) molecules at the air-water interface present an interesting bicompetitive adsorption between primary and secondary hydrophilic groups on either end of an alkyl chain, which, depending on the position of the second hydrophilic group, may lead to a sharp transition from an expanded phase to a crystalline condensed morphology as surface pressure is increased. Here we repo...

Hydrophilic graphene oxide (GO) nanosheets can be easily coated onto stainless steel meshes. Compared to neat meshes, GO coated meshes become more hydrophilic in air and superoleophobic under water. Taking advantage of this completely opposite wettability, GO coated meshes were used for gravity-driven oil-water separation.

In this study, the potential of PTMC and mPEG-PTMC microparticles for controlled delivery of hydrophilic drugs was investigated. PTMC and mPEG-PTMC microparticles, loaded with hydrophilic model compounds (BSA, lysozyme and CoomassieR Brilliant Blue G) were prepared by the double emulsion method. High loading efficiencies can be achieved, and first order release profiles during 60 days were obse...

The cultural supernatant of Mycoplasma fermentans induced interleukin-6 production by human gingival fibroblasts. The active entities were divided into hydrophilic and hydrophobic substances. In this study, we purified a 4.1-kilodalton polypeptide from the hydrophilic substances. It reacted with polyclonal antibodies to M. fermentans and activated human macrophages.

Selective protein fouling on block copolymer micelles with well-known potential for tumour-targeting drug delivery was evidenced by using dynamic light scattering measurements. The stability and interaction of block copolymer micelles with model proteins (BSA, IgG, lysozyme and CytC) is reported for systems featuring a hydrophobic (poly[2-(diisopropylamino)-ethyl methacrylate]) (PDPA) core and ...

The ability of residual antigens on decellularized tissue to elicit the immune response upon implantation motivates development of a more rigorous antigen removal (AR) process for xenogeneic scaffold generation. Antigen removal strategies promoting solubilization of hydrophilic proteins (predominantly cytoplasmic) enhance the reduction of hydrophilic antigenicity in bovine pericardium (BP); how...

In this study a series of epoxy/silica nanocomposites were prepared by using nano silica particles which had different surface modifications. The morphology of the nanocomposite coatings was characterized by scanning electron microscopy SEM. The effects of the hydrophilic and hydrophobic feature of the nano particles on the Tg and anticorrosive properties of nanocomposite coatings were evaluate...

PURPOSE To measure the longitudinal chromatic aberration in vivo using psychophysical and wavefront-sensing methods in patients with bilateral implantation of monofocal intraocular lenses (IOLs) of similar aspheric design but different materials (hydrophobic Podeye and hydrophilic Poday). SETTING Instituto de Optica, Consejo Superior de Investigaciones Cientificas, Madrid, Spain. DESIGN Pro...
