How Nanoparticles Promote The Development And Utilization Of Vaccines
Despite advances in conventional vaccines, improvements are still needed due to concerns about low toxicity, instability, and the need for multiple vaccination. To overcome these problems, nanotechnology has recently been incorporated into vaccine development. With the development of nanotechnology, nanotechnology is playing an increasingly important role in vaccine development, and nanocarriers provide opportunities to enhance cellular and humoral immune responses. The application of nanoparticles in vaccine formulations can not only enhance the immunogenicity and stability of the antigen, but also can target delivery and sustained release. In the past decade, nanoscale materials such as virus-like particles, liposomes, ISCOMs, polymers, inorganic nanoparticles, and emulsions have attracted attention as potential carriers of…

Application of Protease-Responsive Nanocarriers In Near-Infrared Imaging
Cancer is one of the diseases that endanger human health. Successful diagnosis of early cancer is the key to treating and improving patient survival. Therefore, more and more research is focused on the development of dyes and drugs for cancer diagnosis and treatment. However, delivering these therapeutic (drug / dye) molecules to the site of a lesion in the body at an effective concentration is a challenge. With the research on nanotechnology, nanobiotechnology has played an important role in targeted drug application. This technology effectively improves the efficiency of therapeutic diagnostics by increasing the half-life of the molecule, maintaining effective concentrations at the target site, and reducing side effects. Recently,…

Nanoparticle Delivery Technology Crispr-Gold Helps Crispr Treatment of Autism
CRISPR is a repeating sequence in the prokaryotic genome. It is an immune weapon produced by the struggle between bacteria and viruses in the history of life evolution. Simply put, the virus can integrate its own genes into the bacterial genome and use the bacterial cell tools for its own the gene duplication service. In order to remove the foreign invading genes of the virus, Bacteria evolved the CRISPR-Cas9 system. With this system, bacteria can quietly remove the virus gene from its own chromosome, which is the unique immune system of bacteria. Microbiologists have mastered the immune function of bacteria with a variety of excised foreign virus genes. The more…
