A new study shows that polyethylene glycol coatings keep nanoparticles stable during freeze drying, while the protein albumin helps protect other surfaces and improves their safety in use. (Nanowerk ...

Freeze-drying, also known as lyophilization, is a form of dehydration. Food is first frozen, then dried under pressure to remove its water content. It is widely believed that freeze-drying is the best ...

Protein-based drugs can quickly lose activity during transport and storage. To prolong the proteins’ activity, drug firms add stabilizers, including polyethylene glycol and trehalose, a disaccharide ...
