Nanotechnology is increasingly important in vaccine development. As vaccines are evolving toward less immunogenic minimalist compositions, adjuvants and delivery systems that increase the effectiveness of the antigen are of increasing importance. The use of nanoparticles in vaccine formulations not only improves antigen immunogenicity and stability, more importantly, targeted delivery and controlled release are also achieved. Various nanoparticle vaccines of different size, shape, composition and surface properties have been approved for human use, and the number of candidates is increasing. In terms of our extensive experience in delivery system development, Creative Biolabs is proud to offer our clients a series of nanoparticles development for vaccine delivery with the best quality and most competitive price.
