Biological drugs such as gene therapies and messenger RNA (mRNA) vaccines frequently rely on lipid nanoparticles (LNPs) coated in a layer of polyethylene glycol (PEG) to deliver medications to the ...
Researchers have developed a new method to improve the structural and functional stability and long-term storage of hydrogel microparticles during lyophilization. By using polyethylene glycol (PEG) ...
