Association behavior and fluorescence quenching between cationic zinc porphyrin pendant groups on water-soluble polymers and anionic iron porphyrin guests

An amphiphilic cationic tripyridiniumylporphyrin monomer, i.e., ZnTrMPyP, was synthesized and copolymerized with acrylamide in water and dimethyl sulfoxide, respectively, to prepare the water-soluble random copolymer P-D and microblock copolymer …

Dimeric camptothecin-loaded mPEG-PCL nanoparticles with high drug loading and reduction-responsive drug release

Camptothecin (CPT) is a potent and broad-spectrum anti-tumor drug, but its clinical application is limited due to its poor water solubility, toxicity, and low drug-loading potential. Different delivery protocols have been developed to optimize the …

The effects of grafting density and charge fraction on the properties of ring polyelectrolyte brushes: a molecular dynamics simulation study

Using molecular dynamics simulations, the flexible ring polyelectrolyte chains tethered to a planar substrate and immersed in good solvents are investigated systematically. Two sets of simulations are performed to explore the effects of grafting …
