“…Porous nanostructured materials including nanoporous anodic alumina (NAA), , porous silicon (pSi), , mesoporous metal oxides, − mesoporous organosilicas, , and porous polymers , have proven their value as high-performing sensor platforms due to high specific surface-to-area ratio as well as versatile chemistry. The large surface area of these materials can enhance the sensitivity of the device due to the increase in the number of immobilized bioreceptors and thus available binding sites.…”

The emergence of nanostructured materials has opened new horizons in the development of next generation biosensors. Being able to control the design of the electrode interface at the nanoscale combined with the intrinsic characteristics of the nanomaterials engenders novel biosensing platforms with improved capabilities. The purpose of this review is to provide a comprehensive and critical overview of the latest trends in emerging nanostructured electrochemical biosensors. A detailed description and discussion of recent approaches to construct label-free electrochemical nanostructured electrodes is given with special focus on pathogen detection for environmental monitoring and food safety. This includes the use of nanoscale materials such as nanotubes, nanowires, nanoparticles, and nanosheets as well as porous nanostructured materials including nanoporous anodic alumina, mesoporous silica, porous silicon, and polystyrene nanochannels. These platforms may pave the way toward the development of point-of-care portable electronic devices for applications ranging from environmental analysis to biomedical diagnostics.
