Laser ablation or photoablation (also called laser blasting [1] [2] [3]) 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 .
Laser ablation synthesis in solution (LASiS) is a commonly used method for obtaining colloidal solution of nanoparticles in a variety of solvents. [ 1 ] [ 2 ] Nanoparticles (NPs,), are useful in chemistry, engineering and biochemistry due to their large surface-to-volume ratio that causes them to have unique physical properties. [ 3 ]
Laser ablation is not recommended for in vivo, as the potential damage from laser was too high. High cost of operation, and extensive operating time narrowed its accessibility for cell studies. [4] Recently, laser ablation was applied with ICP-MS to develop LA-ICP-MS analysis technique. In which utilizes the precision and ability to change ...
Magnetic nanoparticles can be concentrated to the tumor site via externally applied magnetic field, which is also advantageous in minimizing dose-related side effects. Localized heat can also trigger release of certain anti-cancer immuno-therapeutics loading from the nano-scale cargos if the nanomaterials are heat-responsive.
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
IRE has been in use against prostate cancer since 2011, partly in form of clinical trials, compassionate care or individualized treatment approach. As for all other ablation technologies and also most conventional methods, no studies employed a randomized multi-center approach or targeted cancer-specific mortality as endpoint.

These methods of treatment are usually painful and kill normal cells in addition to producing adverse side effects. CNTs as drug delivery vehicles have shown potential in targeting specific cancer cells with a dosage lower than conventional drugs used, [ 1 ] that is just as effective in killing the cells, however does not harm healthy cells and ...
