What are the Applications of Light Energy in Nanotechnology?
Light energy is harnessed in various applications within nanotechnology:
Solar Cells Nanotechnology has significantly improved the efficiency of solar cells. Nanostructured materials, such as perovskite nanoparticles and nanowires, enhance light absorption and charge separation, leading to higher energy conversion rates.
Phototherapy Light-based therapies, such as photodynamic therapy (PDT), utilize light-activated nanoparticles to target and destroy cancer cells. These nanoparticles can be designed to absorb specific wavelengths of light, making the treatment highly effective and localized.
Sensors Nanotechnology has led to the development of highly sensitive sensors that can detect minute changes in light properties. For example, surface plasmon resonance (SPR) sensors use metallic nanoparticles to detect biomolecular interactions with high sensitivity.
