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 .
Cell ablation can also be used as a tool to produce transgenic organisms lacking a cell type, and as a cure for certain diseases such as cancer. [2] The term is not to be confused with genetic ablation: a method of modifying DNA in order to disrupt the production of a specific gene. [3]
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.
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 ]
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.
A new trend gaining popularity among people trying to lose weight is microdosing the diabetes medication Ozempic. With approximately 70% of American adults meeting the criteria for being obese or ...
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
