Abstract

We report a new fabrication method referred to as ‘drill and fill’ lithography that provides control structuring and excellent reproducibility in the production of patterned platinum electrodes in a chip format, and demonstrate their sensing abilities for the label-free immunodetection of the HER-2 (human epidermal growth factor receptor-2) antigen.
