Nanostructures

Nanostructures are structures that range between 1 nm (molecular scale) and 100 nm in at least one dimension. Most are synthetic and can be engineered to wide range of physical properties. Nano surfaces, cylindrical nanotubes, and Nano spheres are common nanostructures. Nanostructures have revolutionized the field of medicine through their applications in diagnostics, drug delivery, and tissue engineering. Nanoparticles can be engineered to target specific cells or tissues, making them ideal for delivering drugs directly to diseased areas, such as cancerous tumors, while minimizing side effects on healthy tissues. Quantum dots and gold nanoparticles are used in advanced imaging techniques to provide high-resolution images of biological processes at the molecular level. Additionally, nanostructured scaffolds are used in tissue engineering to support the growth and regeneration of damaged tissues and organs.
