In gene therapy research, polymeric nanoparticles are of interest due to their biocompatibility, controlled degradation, and ability to protect nucleic acids from enzymatic degradation in vivo. For example, polymer cationic vectors (PCVs) have shown potential in improving the efficiency of gene transfection due to their low cost, low immunogenicity and tunability. The application of these polymeric materials in drug delivery systems not only improves the stability and bioavailability of drugs, but also enables targeted and controlled release of drugs, thereby improving therapeutic efficacy and reducing side effects. In gene therapy, these materials help deliver nucleic acid molecules safely and efficiently into target cells for gene regulation or therapy.
Based on years of research experience and a professional drug development research team, CD Formulation can provide customers with the development of efficient and reliable polymeric gene carriers to promote the research and application of polymerics for gene delivery in gene therapy species.
We select suitable polymeric materials, such as polyethylene glycol (PEG), polylactic acid-hydroxyacetic acid copolymer (PLGA), polyethyleneimine (PEI), etc., according to the characteristics of our clients' projects, and chemically modify them to improve their transfection efficiency and reduce immunogenicity.
The target gene is complexed with a polymeric carrier by physical or chemical methods to form a stable polymer-nucleic acid complex, which may include electrostatic adsorption, covalent binding, or self-assembly techniques.
The synthesized polymeric carriers and their complexes formed with nucleic acids were characterized for their physicochemical properties, including particle size, surface charge, stability and release characteristics. Based on the characterization, our researchers optimize the polymeric carriers to improve their performance.
The performance of polymeric carriers needs to be tested in models to assess their efficiency and safety as drug or gene delivery vehicles. This includes cell culture experiments, animal model testing, etc.

This article focuses on two potential polymeric carriers, chitosan and poly(amidoamine) dendrimers, which have been widely reported for gene delivery. For chitosan, the interest arises from its availability, excellent non-cytotoxicity profile, biodegradability, and ease of modification. For poly(amidoamine) dendrimers, the interest arises from their ease of synthesis with controlled structure and size, minimal cytotoxicity, biodegradability and high transfection efficiencies.
