The application of science and technology at the nano-scale is redefining fields like imaging, diagnosis, drug delivery, regenerative medicine and biomaterials as well as underpinning the development of new generations of medical products. Many of these advances would offer vastly improved outcomes for patients, therapies for hitherto difficult-to-treat diseases or conditions, improved manufacturing efficiency, and better use of valuable medical professional resources. The technology has already found its way into multifarious applications in healthcare such as diagnostic imaging agents, drug delivery systems, pathogen detection systems, biosensors, tissue engineering, microfluidics, lab-on-a-chip, compact electronic systems.
