Shape Anisotropic Magnetic Particles for high throughput and high efficiecy intracelluar delivery of functional macromolecules
We report a novel intracellular delivery system based on aligning Shape-Anisotropic Magnetic Particles (SAMP) to deliver functional molecules into mammalian cells with high efficiency and high viability. A broad range of molecules (calcein, dextran 3K, dextran 40K, GFP plasmid, SiRNA, and β-lactamase) have been successfully delivered into primary cells with preserved functions. We have achieved high efficiency delivery of enzyme into primary human dermal fibroblast (NHDF), and other large macromolecules (dextran 40K) into mouse cortical neurons.
