    Bioelectronics and biosensors play a crucial role in modern society. The need for selectivity, sensitivity, fast and reliable response raises interest in the use of novel materials. Increased attention has been thus focused on carbon-based materials, namely diamond and graphene, which can provide many advantageous properties. In this paper, we focus on solution-gated field-effect transistors employing the hydrogen-terminated diamond surface as the functional layer for label-free monitoring proteins or cells in real-time. The hydrogen termination of diamond induces a sub-surface two-dimensional p-type channel sensitive to the surrounding conditions (gas molecules, biomolecules, or cells). Here, selected technological approaches in the fabrication of diamond-based solution-gated transistors are discussed.
