UCLA scientists store materials in cells' natural vaults Method may offer safer way to target drugs to living cellsIn the realm of nanotechnology, or study of the tiny, scientists often aim to safely deliver and leave material in the human body without causing harm. A big challenge is how to design a package for this biomaterial that will be compatible with living cells and will not provoke an immune reaction. Previous efforts have relied upon viruses or artificial chemicals to house and deliver drugs or other substances to targeted cells.
