Did you know that the same radical - firm , ultra - intense laser ( UUL ) that can blast individual Crab cells without harming any good electric cell in the vicinity can also be used to fuse metal to bone ? A new laser science lab at the University of Missouri has been build to screen the awesome power of this system , whose pulses last just one one-quadrillionth of a 2d , cognise in street nomenclature as a “ femtosecond . ” Here ’s why the American Dental Association , the American Cancer Society and the Pentagon would be equally interested in this developing technology :
The key feature of the femtosecond laser is the fact that it uniquely can hit its target without burning anything in the environ area . harmonise to Robert Tzou , chief investigator and president of the department of Mechanical and Aerospace Engineering , this could stand for the end of nasty chemotherapy :
“ If we have a way to habituate the lasers to kill cancer cells without even touch the surrounding salubrious cells , that is a tremendous benefit to the patient . Basically , the patient leaves the clinic right away after discourse with no side effects or price . The high-pitched precision and gamey efficiency of the UUL provide for contiguous upshot . ”
In operation and in dentistry , the super accuracy of the laser can be utilized to cut the confirmative damage currently made by incisions and cavity oil production .
X - Men fans will be well-chosen to hear that the laser can also be used to fuse metallic element dust to pearl , “ sinter ” metallic element powder topically with just enough heat , but without the want for molten metal . Says investigator Yuwen Zhang :
“ With the laser , we can melt a very thin strip around Ti micro- and nanoparticles and finally control the porousness of the bridge connecting the bone and the alloy . The procedure take into account the particle to bond strongly , adapt to the two dissimilar surfaces . ”
In case you doubt that metallicized osseous tissue might have military app , Zhang and some of his workfellow have just receive a DoD grant to prod around in on the dot that arena . [ University of Missouri ]
