Abstract: A process for manufacturing a microelectromechanical device envisages: providing a wafer of semiconductor material; forming a buried cavity, completely contained within the wafer, and a structural layer formed by a surface portion of the wafer and suspended over the buried cavity; forming first trenches through the structural layer as far as the buried cavity, which define the suspended structure in the structural layer; filling the first trenches and the buried cavity with sacrificial material; forming a closing structure above the structural layer; removing the sacrificial material from the first trenches and from the buried cavity to release the suspended structure, the suspended structure being isolated and buried within the wafer in a buried environment formed by the first trenches and by the buried cavity.

Abstract: A device for detecting the concentration of biological materials is formed in a body having a plurality of fluidic paths connectable to a multi-microbalance structure carrying a plurality of microbalances, each microbalance having a sensitive portion facing a reaction chamber. The body and the multi-microbalance structure are configured to be mechanically coupled together and each microbalance is configured to be coupled to a respective fluidic path. Each fluidic path includes an inlet, a duct and a liquid waste, each duct being configured to be coupled with a respective reaction chamber. The plurality of fluidic paths and microbalances form at least one first and one second reference cells and one first sample cell.
