A fluorescent and colorimetric sensor based on ionic liquids for the on-site monitoring trace gaseous SO2

Study of the molecular interaction of a phosphonium-based ionic liquid within myo-inositol and non-steroidal anti-inflammatory drugs

“…1(E) and (F) and the CMC data are represented in Table 1 . Che et al 49 performed on-site monitoring of trihexyl(tetradecyl)phosphonium fluorescein ionic liquid to trace SO 2 gas using fluorescent and colorimetric methods. According to the findings, colorimetric dual-signal chemosensors might be employed as smart paper labels for on-site, continuous monitoring of SO 2 levels in the environment.…”

Paper-based colorimetric sensors for point-of-care testing

“…The color change or other visual indicators on the sensor could provide a rapid and convenient diagnostic tool for healthcare professionals to assess the presence and severity of respiratory diseases. 142,143 Additionally, paper-based colorimetric sensors could be used for monitoring parameters relevant to chronic respiratory diseases, such as exhaled nitric oxide or pH levels in breath condensate. These sensors could provide a simple and noninvasive way to measure these parameters, potentially facilitating regular monitoring and disease management for individuals with respiratory conditions.…”
