S16-157 CART- a transfection delivery system for efficient intracellular mRNA delivery Stanford researchers have developed a new class of materials that enable new strategies for the efficient delivery of messenger RNA (mRNA) into cells and animals. The delivery materials are easily prepared (2 steps), stable and readily tuned.
