Photonic Sensors for Health and Environmental Monitoring

Triboelectric nanogenerator assisted synthesis and detection of chemical compounds

“…The repeatability of sensing chemicals is another part of the stability of the TENG that can be enhanced by selecting suitable and elastic materials. 39 Now, selectivity for specific chemicals of the TENG-based sensor can be increased by choosing appropriate frictional layers, filtering the unwanted molecules, 181 and reducing the noise of the output signal of TENGs. 182 Finally, further research can be focused on improving the properties of the TENG in terms of sensitivity, stability, and selectivity.…”

Multivariate Method to Analyze Archaeol in Cattle Feces

“…At the same time, nanoscience and nanotechnology have acquired great importance in current science due to the fact that they allow for the obtaining of cheap sensors that are easy to install in situ. With all this, it is expected that the scope of nanotechnological advances will be such that they will allow for the development of completely new methods and their implementation in all types of industries [3]. It is intended that the developed devices allow for the evaluation of parameters that determine the emission of greenhouse gases (GHG) from livestock through portable, reusable, and non-polluting automated systems, regardless of the need for pre-treatment of the samples and therefore of qualified personnel, making measurements in real time and thus reducing costs [4][5][6][7].…”

Integrated Photonic Sensors for The Detection of Toxic Gases - A Review

“…For instance, detecting trace levels of dangerous gases in industrial environments can avert accidents and ensure worker safety. In environmental monitoring, these sensors can track pollutants with high accuracy, contributing to better air quality management and public health [14][15][16]. In medical diagnostics, integrated photonic sensors can be used for non-invasive breath analysis to detect biomarkers for various diseases, enabling early diagnosis and personalized treatment.…”
