What is Nanotechnology?
Nanotechnology refers to the manipulation of matter on an atomic, molecular, and supramolecular scale. The field covers a wide range of applications and involves the design, characterization, production, and application of structures, devices, and systems by controlling shape and size at the nanometer scale.
Drug Delivery: Nanoparticles can be used to deliver drugs directly to targeted cells, minimizing side effects and improving the efficacy of treatments.
Diagnostics: Nanoscale sensors and imaging agents enable earlier and more accurate detection of diseases.
Tissue Engineering: Nanomaterials can be used to create scaffolds that support the growth of new tissues and organs.
Environmental Applications
Nanotechnology also offers solutions to environmental challenges.
Nanomaterials can be used for water purification, air filtration, and improving the efficiency of renewable energy sources.
Water Purification: Nanomaterials can remove contaminants and pathogens from water, providing clean drinking water.
Air Filtration: Nanoscale filters can capture pollutants and improve air quality.
Renewable Energy: Nanotechnology enhances the efficiency of solar cells and batteries, contributing to sustainable energy solutions.
