Fluorimetric detections of nitroaromatic explosives by polyaromatic imine conjugates

Recent advances in aggregation-induced emission (AIE)-based chemosensors for the detection of organic small molecules

“…Recently, Kose et al reported hydrazine-imine conjugates containing polyaromatic groups ( D31 ) as fluorescent probes for NACs including PA, DNP, NP and NB. 371 The LODs recorded were 0.74, 0.74, 0.81 and 0.013 μM, respectively. On the other hand, Sarma et al developed pyrene based AIE active fluorescent probe, dimethyl-5-(pyren-1-ylmethyleneamino)isophthalate ( D32 ) which can detect NACs such as PA in both aqueous and solid state, with an LOD of 10 nM.…”

Sodium-Polyacrylate-Based Electrochemical Sensors for Highly Sensitive Detection of Gaseous Phenol at Room Temperature

“…Phenol and other phenolic compounds are typically detected with techniques such as gas chromatography coupled to mass spectrometry , and/or solid-phase microextraction, , various spectroscopic techniques (surface-enhanced Raman spectroscopy, infrared spectroscopy, colorimetry, fluorimetry), and electrochemical sensing approaches (piezoelectric, , capacitive, chemiresistive, , amperometric, , voltammetric, , impedance). Although these routes offer promising analytical opportunities, there remains a need to develop robust, inexpensive, and disposable detectors that can be deployed autonomously without the need for laborious sample pretreatment or specific experimental conditions, such as increased temperature in the case of chemiresistive sensing.…”
