Other polymer nanoparticles as promising tools for anticancer therapeutics

Polymeric nanoparticles (PNPs) are a growing interest among researchers in cancer treatment during recent years, particularly because of their site-specific and sustained release drug delivery that resulted in less side effects and systematic toxicity. Among PNPs, poly sulfonic acids, poly carboxylic acids, poly boronic acid, and poly silamine are also emerging as novel PNPs for anticancer therapeutics. These groups impart various physical and chemical properties to drug delivery systems when used as surface modifiers in nanoparticles or as inserted as a functional group in nanoparticles to form nanogels. In addition to antitumor and antiangiogenesis activity, these polymeric groups also increase the specific targeting of anticancer drugs.
