Poly(silyl ether)s as Degradable and Sustainable Materials: Synthesis and Applications.

Polymer research is currently focused on sustainable and degradable polymers which are cheap, easy to synthesize, and environmentally friendly. Silicon-based polymers are thermally stable and can be utilized in various applications, such as columns and coatings. Poly(silyl ether)s (PSEs) are an interesting class of silicon-based polymers that are easily hydrolyzed in either acidic or basic conditions due to the presence of the silyl ether Si-O-C bond.

Doxorubicin delivery via magnetic nanomicelles comprising from reduction-responsive poly(ethylene glycol)‑b‑poly(ε‑caprolactone) (PEG-SS-PCL) and loaded with superparamagnetic iron oxide (SPIO) nanoparticles: Preparation, characterization and simulation.

Reduction-responsive biodegradable micelles were prepared by linking of poly(ethylene glycol) and poly(ε‑caprolactone) with disulfide bond (PEG-SS-PCL) for co-delivery of superparamagnetic iron oxide (SPIO) nanoparticles (NPs) and an anticancer agent, doxorubicin (DOX). This amphiphilic diblock copolymer shows redox-responsive properties, which is arising from disulfide bonds throughout the main chain. The ability of these copolymers for self-assembly with oleic acid modified SPIONs can help to organize nanomicelles in aqueous solution.
