High-Performance Multipanel Biosensors Based on a Selective Integration of Nanographite Petals

We report the first selective growth of nanographite petals and various carbon nanomaterials onto a multipanel electrochemical platform. Different types of nanomaterials can be obtained by fine-tuning the growth parameters of the chemical vapor deposition (CVD) process. First, absolute novelty is the catalytic CVD selective growth of different carbon nanomaterials only on the working electrodes of the platform. A second novelty is the growth obtained at complementary metal–oxide–semiconductor compatible temperatures. These novel electrodes have been incorporated in sensors in which performance characteristics improve with the content of nanostructures. Unprecedented sensing parameters with respect to both direct and enzyme-mediated electrochemical biodetection have been obtained.
