Nanotechnology is a field of applied science, focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. During the last twenty years, scientists have been looking towards nanotechnology for the answer to problems in medicine, computer science, ecology and even sports. In particular, new and improved techniques for pollution control are emerging as nanoparticles push the limits and capabilities of technology.Environmental remediation includes the degradation, sequestration, or other related approaches that result in reduced risks to human and environmental receptors posed by chemical and radiological contaminants. The benefits which arise from the application of nanomaterials for remediation include faster cleanup of wastes. However, cost-effective remediation techniques pose a major challenge in the development of adequate remediation methods that protect the environment.
Since their discovery in 1991, carbon nanotubes (CNTs) have stirred considerable excitement in both the academic research community and among industry sectors due in large part to the technology’s potential for a broad range of new applications.
