Nanotechnology In Physical Therapy

Abstract

Nanotechnology has emerged as an imperative field in many scientific domains. According to National Nanotechnology Initiative, nanotechnology is defined as the understanding and control of matter at dimensions between approximately 1 to 100 nanometers, where unique phenomena enable novel applications. Among the various nanoparticles being studied, zinc oxide (ZnO) nanoparticles have shown great potential in the healing and treatment of various ailments. These nanoparticles are well known for their exceptional properties, for instance, their high surface area to volume ratio, high reactivity, high cell-penetrating properties and photoluminescence. These features make them ideal for use in physiotherapy as well. One of the most promising uses of ZnO nanoparticles in physical therapy is wound healing. Studies have shown that these can help to promote the growth of new tissues, can reduce inflammation by reducing inflammatory mediators and the most evident effect is the prevention of bacterial infection at the site of injury. Other than wound healing and its antibacterial properties, antigenic and antineoplastic applications are also valuable.
