Worldwide female breast cancer is the most commonly diagnosed cancer, with an estimated 2.3 million new cases in 2020, reason for the need of targeted therapies that can maximize treatment success and minimize toxicity. Nanoparticles of gold (AuNps) exhibit cytotoxic properties against certain types of cancer cell lines. Nanofibers have been use in the drug delivery systems due to its degradability and high surface area. We proposed a membrane with nanometric fibers using polivinilic alcohol (PVA) and chitosan (Qts) loaded with AuNps and Doxorubicin (Doxo) with the purpose of diminish tumor regression.
PVA-Qts membrane was develop with electrospinning, the injection, …

Nanoparticulate composites of hydroxyapatite (HAp) and chitosan were synthesized by ultrasound-assisted sequential precipitation and characterized for their microstructure at the atomic scale, surface charge, drug release properties, and combined antibacterial and osteogenic response. Crystallinity of HAp nanoparticles was reduced because of the interference of the surface layers of chitosan with the dissolution/reprecipitation-mediated recrystallization mechanism that conditions the transition from the as-precipitated amorphous calcium phosphate phase to the most thermodynamically stable one—HAp. Embedment of 5–10 nm sized, narrowly dispersed HAp nanoparticles within the polymeric matrix mitigated the burst release of the small molecule model drug, fluorescein, bound to HAp by physisorption, …
