ABSTRACT
This chapter discusses graphene-based templates for three main applications: biological and chemical sensing, photovoltaics, and catalysis. Graphene nanomeshes (GNMs) are porous graphene structures formed by fabricating pores in a graphene sheet. Depending on the details of the pore lattice, GNMs can be semiconducting, with a fractional eV electronic gap. The gap can be utilized to form a charge sensor, in which the sensing mechanism is based on the boost of the electronic conductance of the GNM. Chemical vapor deposition graphene is a more desirable platform because of the ease of fabrication, scalability, and its inherent low cost. The advances in graphene fabrication technologies and the possibility to grow large-area graphene sheets allowed it to be a promising candidate for several potential applications, in which one of them is biosensing. Transparent conducting electrodes constitute a crucial component of photovoltaic and display technologies.
