Altering Gene Expression with Gold Nanorods and an NIR Laser

Japanese scientists have used lipid coated gold nanorods to deliver a gene vector, which when heated with a near infrared laser (780 nm) released a cytotoxic protein, killing cancer cells.   The proof of principal came with taking the same approach, only ending with the expression of a green fluorescent protein.  MORE
