  • Patent number: 11473107
    Abstract: Methods, tip assemblies and kits are provided for introducing material into cells. The tip assemblies include an attachment portion, a channel portion, and a constriction that function to reduce fluid pressure as a fluid passes through the constriction portion from the channel portion, whereby the tip assemblies form pores in the membranes of cells and introduce material into the cells. The material includes for example one selected from the group of: an inorganic compound, a drug, a genetic material, a protein, a carbohydrate, a synthetic polymer, and a pharmaceutical composition.
    Type: Grant
    Filed: July 15, 2019
