I worked on the development of bioresorbable sensors for sensing of relevant analytes or drug monitoring and nano medicine applications. The focus was on the optimization aspects of the manufacturing process, all performed in the laboratory, and on the characterization of the electrical parameters of the sensor itself.

In this work, i fabricated Field Effect Transistors (FETs) for NO2 sensing, using Metal Assisted Chemical Etching (MACE)-prepared SiNWs as the sensing material. The SiNWs are dispersed on SiO2 / Si substrates between the drain and source contacts made by physical vapor deposition deposition (PVD) of various metals (Au, Al, Ti, Cr); the back-gate is achieved by depositing Au on the back of the SiO2 / Si substrate. The SiNWs-FETs were electrically characterized (output characteristics and trans-characteristic) highlighting a p-type behavior, both in the case of using SiNWs produced from n-type and p-type wafers. FETs made with p-type SiNWs and with drain and source electrodes manufactured with 200nm of Au were employed in the detection of oxidizing (NO2) and reducing (CO) gases. The devices did not show a significant change in electrical characteristics following exposure to CO, while a clear response was observed, in terms of variation of the conduction current for a given polarization, following exposure to NO2.
