Nanoprobe implantation into mammalian cells by cationic transfection.
Submicron-sized Au particles and Au/SiO(2) nanocomposites (superparticles) as large as 670 nm have been introduced into tsA201 cells with minimal cell trauma by cationic transfection systems. Successful implantations can be characterized by the expression of co-transfected DNA.
