What are polyacrylates nanoparticles?

Polyacrylates are an important class of soft, tough and rubbery polymers, which are known for their high transparency, good impact toughness and elasticity. Polyacrylates and their copolymers are one of the polymeric nanoparticles (NPs).

Polymeric nanoparticles are particles within the size range from 1 to 1000 nm and can be loaded with active compounds entrapped within or surface-adsorbed onto the polymeric core. The term “nanoparticle” stands for both nanocapsules and nanospheres, which are distinguished by the morphological structure. Polymeric nanoparticles have shown great potential for targeted delivery of drugs for the treatment of several diseases.

Polymeric nanoparticles have attracted great interest in both academic and industrial fields owing to their potential applications in drug delivery, separation sciences, catalysis, diagnostic imaging, soil remediation, and so on.

Are polymeric nanoparticles toxic?

Biocompatibility, biodegradability and non-toxicity are the main characteristics of polymeric NPs. They are safe for human use and can improve the bioavailability of the loaded drugs. The great importance that is given to these nanocarriers is due to their good stability and the ability to encapsulate a high amount of substances. A recent report has indicated that many biodegradable and non-biodegradable polymeric nanocarriers can be applied for oral drug delivery.

How to obtain polyacrylate nanoparticles?

Polyacrylate nanoparticles can be obtained by addition polymerization of vinyl groups with the molecular structure of monomer. This method has received much attention due to good film-forming property, low cost, controllable size, low toxicity, and ease of synthesis.

Actually, various methods have been used to fabricate polyacrylate nanoparticles, such as the epitope polymerization technique, the supramolecular self-assembly approach, and the spray drying method. Comparatively, the emulsion polymerization is more economical, environment-friendly, and simple.
