Nanotechnology could be simply defined as the design and production of structures, devices and systems by controlling shape and size at nanometre scale.
Nanotechnology is emerging as one of the most promising and rapidly expanding fields of R&D. Nanotechnology expectations for improving the safety and quality of life are high. Nanotechnology offers potential industrial solutions to many problems using emerging nanofabrication techniques.
The potential contributions of advances in nanoscale phenomena to improving human health created even more excitement by envisioning new biomaterials, devices and techniques for biological detection and remediation. Thus, issues such as synthesis, fabrication and characterization of functional nanomaterials and nanostructures for biomedical applications (molecular recognition, nanotubes, nanowires, nanoparticles, self-assembly, polymer-based nanomaterials, thin films, medical imaging, diagnosis and therapy, etc.) become very important.
