What is SiO₂ and Why is it Important in Nanotechnology?
Silicon dioxide (SiO₂), also known as silica, is a versatile material that finds extensive applications in nanotechnology. Due to its unique properties such as high thermal stability, excellent optical transparency, and mechanical strength, SiO₂ is used in various fields ranging from electronics to biotechnology.
SiO₂ nanoparticles: These are widely used in drug delivery systems, biosensors, and as fillers in nanocomposites.
SiO₂ thin films: These are essential in microelectronics and photonics for insulating layers, waveguides, and protective coatings.
SiO₂ nanoshells: Used in biomedical applications for imaging and therapeutic agents.
Biomedical applications: SiO₂ nanoparticles are used for targeted drug delivery, cancer therapy, and bioimaging.
Electronics: SiO₂ thin films serve as insulating layers in integrated circuits and transistors.
Optics: SiO₂ is used in the fabrication of optical fibers and lenses due to its transparency and low optical loss.
Environmental science: SiO₂ nanoparticles are used in water purification and as catalysts in environmental remediation processes.
