Remote‐Controllable Explosive Polymer Multilayer Tubes for Rapid Cancer Cell Killing
2015
Gold nanoshell-functionalized polymer multilayer tubes can be used as potent therapeutic agents for remote killing of cancer cells in a controlled manner due to the emerging pressure wave and tube fragments piercing the cell wall. The explosion is based on rapid evaporation of water inside the tubes caused by photothermal effects. The mechanism of explosion is presented in theory and experi-ment. The explosion of the tubes depends on the absorp-tion coeffi cient and size of the gold nanoshells in the tubes, whereby the placement of the gold particles inside or outside of the tubes has no obvious effect on the explosive properties.
