Applications of laser in medicine and biology
Research has indicated that medics can use laser light to recover numb nerves and physical impairments like impaired limbs. If a laser beam of moderate intensity interacts with these affected areas, the cells will rejuvenate resulting in healing and reconnection of muscles. The introduction of low laser radiations with low monochromatic frequency can help to formation of free radicals, which the body uses for activating fluids like immunoglobulins and red blood cells. Consequently, the body creates enzymes, which in turn provide the convulsive environment for digestion.
Lasers find application in a variety of medicine ranging from malignant tumors to cardiovascular treatments. For example, from research discoveries, laser-induced fluoresce is important in performing experiments that will decide or identify certain diseases. Physiologists use photochemical reactions to determine biological therapy, which heals tissues and enhances molecular count. Photodynamic therapy popularly known as PDT- laser application, used in healing skin effects created by strong laser radiations, is an application of laser technology. Optical properties are now applicable in medicine, where laser-induced fluorescence treatments illuminate ill tissues. Medics use Ruby lasers in a number of medical applications like removing skin scars, wrinkles, and some dominant stretch marks. In eye surgery, doctors use lasers to treat eye cornea problems. On the other hand, medics use laser scalpel technology in general medicine – gynecology, laparoscopic, and surgery. In dentistry, doctors do endodontic surgery effectively using laser light, whereby it allows oral maxillofacial surgery and tooth removal or whitening. Therapeutically, laser techniques like photobiomodulation apply lasers in therapy processes to heal patients.
