Nanotechnology is an emerging science and technology, which is mainly applied in the field of manufacturing and surface modification, and is characterized by a particle size of less than 100 nanometers, good dispersion, and unique physical, chemical and biological properties. Nanotechnology has a wide range of applications in drug discovery, medical testing, biosensors, environmental testing, energy-saving catalysts, wastewater treatment, supercapacitors, optical devices, new energy storage, pollution control, and antiviral drugs.
Nanotechnology can change the way of drug delivery and make the drug penetrate the cells more effectively, thus improving the bioavailability of the drug, reducing the residual of harmful substances, prolonging the action time of the drug, improving the activity of the drug and reducing the harmful side effects. Nanotechnology can also be used in medical testing to detect tiny biomolecules, detect bacteria, viruses, and cancer cells, and perform rapid and accurate diagnosis for better treatment of diseases.
Nanotechnology can also be used for environmental pollution control, which can effectively reduce the toxicity and residual amount of pollutants, improve the efficiency of pollution control, reduce the environmental pollution and risk, and can improve the treatment capacity of pollutants on the original basis. In addition, nanotechnology can also be used for solar energy storage, supercapacitors, optical devices, gas sensors and other applications, which can achieve fine control, improve efficiency, reduce costs and be more environmentally friendly.
