What Types of Nanoparticles are Used in Vaccine Formulations?
Several types of nanoparticles are used in vaccine formulations, including lipid nanoparticles, polymeric nanoparticles, inorganic nanoparticles, and virus-like particles (VLPs). Lipid nanoparticles are particularly prominent due to their biocompatibility and ability to encapsulate both hydrophilic and hydrophobic compounds. Polymeric nanoparticles offer customizable properties for controlled release, while inorganic nanoparticles can provide adjuvant effects. VLPs, which mimic the native structure of viruses, are effective in eliciting strong immune responses.
