Spectroscopic investigations of dendritic polymers as molecular containers
… probe phenol blue will associate with the dendritic polymers polypropyleneimine (PPI) and polyamidoamine (PAMAM). The phenol blue will associate with the core of the dendrimer molecules. This association revealed previously unknown information about the microenvironment of the dendrimer …

Development of Dendritic Polymers as a Modular Drug Delivery Platform for Avascular Tissues
Avascular tissues, such as articular cartilage, meniscus, intervertebral discs, and cornea stroma, pose a number of challenges for disease treatment. Systemic therapies will not reach the target tissue at efficacious levels. Local therapies are rapidly cleared from the tissue due to turnover of …

Stabilization of Submicron Metal Oxide Particles in Aqueous Media
… groups on the adsorption properties of polymers. In addition, the effect of chain architecture as well as the impact of a hydrophobic end-group on polymer adsorption properties was determined. To complement the adsorption studies, a streaming potential instrument was built for use in …

On the dynamics and interparticle forces of electrostatically stabilized colloidal suspensions
… like micelles, vesicles, nanocapsules, and dendritic polymers. Typically, these systems are approached through the Derjaguin–Landau–Verwey–Overbeek (DLVO) theory and Poisson-Boltzmann models, frameworks that approximate charged particles as point charges to predict interparticle …

Synthesis and Characterization of Poly(arylene ether sulfone)s with Novel Structures and Architectures
Poly(arylene ether sulfone)s with dendritic terminal groups were synthesized by step-growth polymerization of two difunctional monomers in the presence of preformed dendritic end-cappers. These polymers were characterized by NMR, SEC, DSC, TGA, melt rheology and tensile tests. The melt viscosities …
