New hybrid nanoparticles offer precise cell targeting

A research team drawn from the National Institute of Standards and Technology, the University of Maryland and the FDA has developed a method to combine two substances into a hybrid nanoscale particle capable of precise drug payload delivery through a target cell's membrane.

To get the hybrid particle the team combined a phospholipid membrane "bubble" called a liposome and particles of hydrogel, a water-filled network of polymer chains. The hybrid combines the targeting abilities of liposomes with the durability of the hydrogel, overcoming a tendency to rupture without the hydrogel's tendency to clump together.

The liposome-hydrogel hybrid vesicles are irradiated, adding strength to the delivery particles, which can be loaded with a therapeutic payload during the manufacturing process.
