What is Nanotechnology?
Nanotechnology refers to the science, engineering, and application of materials and devices with dimensions on the nanoscale, typically less than 100 nanometers. At this scale, materials often exhibit unique physical, chemical, and biological properties that differ from their larger-scale counterparts.
IBM - Known for its research in nanoscale electronics and quantum computing.
Intel - Pioneering the use of nanotechnology in semiconductor manufacturing.
Nantero - Specializes in carbon nanotube-based memory devices.
Nanoco Technologies - Focuses on the development of quantum dots for displays and solar cells.
Applied Nanotech - Develops nanomaterials for applications in electronics, energy, and healthcare.
Electronics - Companies like Intel and IBM use nanotechnology to create smaller, faster, and more efficient processors and memory devices.
Healthcare - Nanotechnology is used in drug delivery systems, diagnostic tools, and medical imaging. For instance,
Nanospectra Biosciences uses nanoshells for targeted cancer therapy.
