Researchers have used laser-induced explosion of absorbing nanoparticles in selective nanophotothermolysis of cancer.
This is realized through fast overheating of a strongly absorbing target during a short laser pulse. The resulting explosion of nanoparticles may be accompanied by optical plasma and shock waves with supersonic expansion and particle fragmentation with fragments of high kinetic energy. These can contribute to the killing of cancer cells.
