Engineering a new class of nanocomposite-metamaterials can achieve ultra-sensitive sensors for bio-imaging, gas detection, air and food contamination control. This is critical to meet the global challenges of environmental conservation and efficient use of energy and mineral resources, especially for point-of-use applications. Using anodic aluminium oxide (AAO), here we report the fabrication of metamaterials with different metal nanostructures, we also investigate the applications of these fabricated metamaterials based on AAO templates.
