Ophthalmic Laser Therapy: Mechanisms and Applications

چکیده

Molecules are made up of atoms, which are composed of a positively charged nucleus and negatively charged electrons orbiting it at various energy levels. Light is composed of individual packets of energy, called photons. Electrons can jump from one orbit to another by either, absorbing energy and moving to a higher level (excited state), or emitting energy and transitioning to a lower level. Such transitions can be accompanied by absorption or spontaneous emission of a photon.

An overview of therapeutic applications of ultrasound based on synergetic effects with gold nanoparticles and laser excitation

Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...
