Preparation of nanoparticles by Laser in Solution. Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma.
Radiofrequency ablation is a procedure that creates a nerve lesion produced by localized heat. When the lesion is placed over a painful nerve, pain signals are interrupted and pain perception by the brain is decreased. The procedure is performed in an outpatient setting.
