Red blood cells are amazing. They pick up oxygen from our lungs and carry it all over our body to keep us alive. The hemoglobin molecule in red blood cells transports oxygen by changing its shape in an all-or-nothing fashion. Four copies of the sa...

Getting big molecules into cells isn't easy, and it isn't easy on the cells, either. Bulk electroporation blows holes throughout the cell and can kill many of them. Viruses like AAV have limited capacity for macromolecules like Cas9, and...
