Dispersion of the Photosensitizer 5,10,15,20-Tetrakis(4Sulfonatopheny1)-porphyrin by the Amphiphilic Polymer Poly(vinylpirrolidone) in Highly Porous Solid Materials Designed for Photodynamic Therapy
(2017)
The ability of the amphiphilic and biocompatible poly(vinylpyrrolidone) to avoid self-aggregation of the photosensitizer 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin in aqueous solution in the presence of the biocompatible ...
Bicontinuous networks made of polyphosphates and of thermoplastic polymers

A new method for producing highly concentrated non-aqueous dispersions of silver nanoparticles and the evaluation of their bactericidal activity
(Springer, 2014-11-01)
Different preparation methods of silver nanoparticles (AgNP) are well described in the literature, most of them in aqueous medium. Aqueous dispersions of AgNP normally have a limited capacity to tolerate high nanosilver ...
Encapsulation of Clay Within Polymer Particles in a High Solids Aqueous Dispersion
(American Chemical Society, 2013-07)
By using a two-step polymerization process, it was possible to encapsulate clay platelets within polymer particles dispersed in water. First, seed polymer particles with chemically bonded clay were obtained by batch ...

Dispersing carbon nanotubes in phenolic resin using an aqueous solution
(2011-11-01)
The ability to control the carbon nanotube (CNT) dispersion in polymers is considered the key to most applications of nanotube/polymer composites. The carbon nanotube dispersion into water with different surfactants, as ...

Solid dispersion technology as a strategy to improve the bioavailability of poorly soluble drugs
(Future Medicine, 2019-05)
Over the last half-century, solid dispersions (SDs) have been intensively investigated as a strategy to improve drugs solubility and dissolution rate, enhancing oral bioavailability. In this review, an overview of the state ...
