Nanocontainer ships titan-size gene therapies and drugs into cells

Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size—even hefty ones attached to the gene-editing tool called CRISPR. If their creation—constructed of a biodegradable polymer—passes more laboratory testing, it could offer a way to efficiently ferry larger medical compounds into specifically selected target cells.
