Fat removal procedures are used mostly in cosmetic surgery with the intention of removing unwanted adipose tissue.The procedure may be invasive, as with liposuction, [1] or noninvasive using laser therapy, radiofrequency, ultrasound or cold (cryoablation or cryolipolysis) to reduce fat, sometimes in combination with injections.
Liposuction, or simply lipo, is a type of fat-removal procedure used in plastic surgery. [1] Evidence does not support an effect on weight beyond a couple of months and does not appear to affect obesity-related problems. [2] [3] In the United States, liposuction is the most common cosmetic surgery. [4] [5]
It can be combined with liposuction to help tighten and smooth over the new contours after removal of excess fat. Resurfacing can be ablative, which vaporizes tissue and creates wounds, or non-ablative which keeps the skin intact. Laser resurfacing is usually done with a 2940 nm Er:YAG laser or a 10,600 nm CO 2 laser.
Tumescent liposuction is a technique that provides local anesthesia to large volumes of subcutaneous fat and thus permits liposuction. While the suctioned fat cells are permanently gone, after a few months overall body fat generally returned to the same level as before treatment. [1] This is despite maintaining the previous diet and exercise ...

In 2015, successful laser post-ionization was reported, using a modified MALDI source operated at an elevated pressure of ~3 mbar coupled to an orthogonal time-of-flight mass analyzer, and employing a wavelength-tunable post-ionization laser, operated at wavelength from 260 nm to 280 nm, below the two-photon ionization threshold of the matrices ...
Fluorescence recovery after photobleaching (FRAP) is a method for determining the kinetics of diffusion through tissue or cells. It is capable of quantifying the two-dimensional lateral diffusion of a molecularly thin film containing fluorescently labeled probes, or to examine single cells.
Laser lithotripsy was introduced in the 1980s. Pulsed dye lasers emit 504 nm ( cyan -colored) light that is delivered to the stone by optical fibers through a scope. Holmium:YAG lasers were developed more recently and produce smaller fragments.
