abstract = {Amphetamine (AA) is used in some therapeutic treatments, but it is also one of the most widely used illicit drugs. Therefore, a correct tracking of AA in various environments is crucial for its controlled distribution even inside the human body. However, current sensors are still too large to fit inside the human body and their biocompatibility is still deficient. Since the discovery of nanostructures, especially silicon nanowires (SiNWs), the possibilities of sensors inside the human body have increased due to their enhanced properties and biocompatibility. However, theoretical studies about the capabilities of SiNWs with surface modifications as sensing materials are still scarce. Using Density Functional Theory, we investigate the effects of amphetamine adsorption on the work function, and other electronic and structural properties, of pristine and modified SiNWs. Two types of modifications were studied, i.e., substitutional doping with B, Al, and Ga atoms and surface functionalization with the same species. The adsorption energies of the amphetamine molecule are larger for the doped nanowires, followed by the functionalized ones, and lastly, the undoped Si nanowire.This study shows that undoped, doped, and functionalized SiNWs are excellent candidates for AA sensing, with B being the best chemical species for improving AA adsorption for both doped and functionalized schemes.},

abstract = {The threat that ammonia (NH3) poses in various human activity environments drives the necessity of sensors of higher sensitivity. Two-dimensional (2D) materials have attracted attention for this particular purpose, with 2D silicon carbide being one prospect for this application. However, this potential use has been relatively unexplored. In this work, we study the adsorption of NH3 on pristine and metal (Li, Na, Mg, Ca, Ag, Au, Cu, Pd, and Ti) decorated silicon carbide monolayers (2D-SiC) using a first-principles approach based on Density-Functional Theory. Energetic analyses were performed to determine the enhancement or deterioration of the NH3 adsorption capacities of the 2D-SiC. The results show that the Ag- and Au-decorated monolayers are the best candidates for NH3 capturing due to the large adsorption energies found in these systems.},
