This paper describes a method by which molecules that are impermeable to cells are encapsulated in dye-sensitized lipid nanocapsules for delivery into cells via endocytosis. Once inside the cells, the molecules are released from the lipid nanocapsules into the cytoplasm with a single nanosecond pulse from a laser in the far red (645nm). We demonstrate this method with the intracellular release of the second messenger IP3 in CHO-M1 cells, and report that calcium responses from the cells changed from a sustained increase to a transient spike when the average number of IP3 released is decreased below 50 molecules per nanocapsule. We also demonstrate the delivery of a 23 kDa AGT fusion protein into Ba/F3 cells to inhibit a key player BCR-ABL in the apoptotic pathway. We show that an average of ~ 8 molecules of the inhibitor is sufficient to induce apoptosis in the majority of Ba/F3 cells.
