Nanostructured ZnO For Electrochemical Biosensors

Abstract

Biosensors have become important and practical tools in pathogen detection, molecular diagnostics, environmental monitoring, food safety control, and homeland security. Of these, electrochemical biosensors are of particular interest due to several combined advantages such as low cost, ease of operation, and miniaturization capability. A current goal for these types of biosensors is of becoming point-ofcare diagnostic devices. Much effort has been put into improving key performance parameters, such as sensitivity, specificity, recognition rates, and multiplexing capabilities for parallel recognition, to allow this possibility.
