The pH‐responsive amphiphilic polyphosphazenes bearing N,N‐diisopropylethylenediamine (DPA) have been proven to be promising nanovehicles for drug antitumor therapy. To further modify these amphiphilic polyphosphazenes with fluorescent labeling agent or other biochemical functional groups, serine methyl ester containing active chemical group NH2 was chosen to be introduced to get a novel polymer...
This study involved the construction of self-assembled nanoparticles from novel pH-sensitive amphiphilic polyphosphazenes. These nanoparticles provide fast pH-responsive drug release and have the capability to disturb endosomal membranes. The polymers were prepared by linking N,N-diisopropylethylenediamine (DPA) onto a backbone of PEGylated polyphosphazene. In vitro cell viability measurements demonstrated...
A series of amphiphilic graft polyphosphazenes with hydrophilic weight fraction ranging from 0.40 to 0.55 were synthesized. These copolymers could self-assemble into distinct aggregates in aqueous solutions. Spherical micelles were observed for the copolymer sample with higher hydrophilic weight fraction. However, when the hydrophilic weight fractions decreased to less than 0.50, vesicle-like polymersomes...
