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 ]
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]
Nanotechnology in thermal ablation and immunotherapy Currently nanotechnologies has been continuously developed for cancer immunotherapy for their versatility in integration of therapeutic and diagnostic (or termed 'theranostic') multimodalities.
A popular method involves mechanical break apart bulk materials into nanomaterials is 'ball milling'. Besides that, nanoparticles can also be made by laser ablation which apply short pulse lasers (e. g. femtosecond laser) to ablate a target (solid). [49]
Laser absorption on the target surface and laser ablation of the target material and creation of a plasma; Dynamic of the plasma; Deposition of the ablation material on the substrate; Nucleation and growth of the film on the substrate surface; Each of these steps is crucial for the crystallinity, uniformity and stoichiometry of the resulting film.
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 ...
All well-established techniques of carbon nanotube growth, such as arc-discharge, [3] [14] laser ablation [15] [16] and chemical vapor deposition, [17] are used for mass-production of BN nanotubes at a tens of grams scale. [13] BN nanotubes can also be produced by ball milling of amorphous boron, mixed with a catalyst (iron powder), under NH 3 ...
