Vesicles are microscopic sacs that enclose a volume with a molecularly thin membrane. The membranes are generally self-directed assemblies of amphiphilic molecules with a dual hydrophilic-hydrophobic character. Biological amphiphiles form vesicles central to cell function and are principally lipids of

文章

Reversible addition–fragmentation chain transfer (RAFT) polymerization is rapidly moving to the forefront in construction of drug and gene delivery vehicles.

The development of drugs that target specific locations within the human body remains one of the greatest challenges in biomedicine today.

Professor Robert K. Prud’homme introduces flash nanoprecipitation (FNP) for nanoparticle fabrication, which is a scalable, rapid mixing process for nanoparticle formulations.
