Nanostructured ZnO and ZnO/nanocarbon composites for biosensing applications


The expanding interest regarding biosensing and early diseases’ diagnosis has led to an exponential growth of R&D efforts in order to find the most suitable materials and sensing mechanisms to achieve high sensitivity and selectivity at low production cost. In this framework, the present project envisages the development of ZnO-based nanostructures to be employed in the fabrication of optical and electrochemical devices for the detection of pathogenic bacteria and biomedical analytes like prostate specific antigen, among other important biological indicators. The ZnO and ZnO/nanocarbon composite nanostructures will be produced by up-scalable laser processing techniques and will be employed as transducers in a sensor device. These structures will be functionalized to immobilize the desired biorecognition receptor which will confer the selectivity to the target analyte. Their technological potential for being incorporated in a biosensor will be evaluated and prototypes will be produced.
