Abstract

Nowadays, there is great concern about the so-called emerging pollutants owing the impacts they can cause on human health and in the environment. In this context, the development of analytical methods that present high sensitivity, and speed in the diagnosis of these compounds, even when presented in extremely low concentrations, are of enormous relevance. For this purpose, several analytical techniques have been used, however many of them have long analysis time, high cost and require trained personnel for operation and results interpretation. In this way, the manufacture of sensors which have high sensitivity, cheap and easy to handle in the robust detection of emerging pollutants is essential. Therefore, this project proposes the development and construction of platforms containing two-dimensional nanomaterials for emerging pollutants sensing, including agricultural pesticides. These platforms will be obtained through 3D printing and potentially modified with 1D nanomaterials, such as electrospun nanofibers, in turn modified with 2D nanomaterials (graphene oxide, molybdenum disulfide and MXenes). Additionally, the 2D materials used will be superficially modified with a laser, in order to increase the detection capacity of the platforms. Additionally, the 2D materials will be surface modified with laser, aiming to increase the performance of the sensors in terms of sensitivity and detection limit of emerging pollutants..
