Tissue-Specific RNA Carriers Give Cell-Level Delivery Confirmation

Neither nuclease nor immunostimulation nor endosomal barrier stays these nanocarriers from the swift completion of their appointed rounds. Reassuring words. But if you’re sending an RNA-based drug, you’d still like some sort of delivery confirmation.To date, nanoparticle delivery services have offered DNA barcodes, which are sort of like tracking numbers, except that looking them up has required genetic sequencing. Not terribly convenient, and not so informative—not at the cell
