Researchers are rolling out the nanobarrels to dispense a keg full of nanosized disks to cure what ails you. NanoWerk tells us about a UCLA team that is tapping into naturally occurring nanosized "vaults," shaped like barrels, found in the cytoplasm of all mammalian cells. Their hollow interiors make them perfect for engineering into drug delivery vehicles. UCLA doctoral student Daniel Buhler came up with the idea to package yet another nanoparticle--what researchers are calling "nanodisks" (NDs) inside the vault. That way, multiple NDs can be packaged inside the vault, increasing local drug concentration. Article
