“…Light-induced fluorescence dental imaging Field [100][101][102] has recently gained considerable attention as a useful tool for diagnosing small cracks and cracked teeth at an early stage. For real-time diagnosis, fluorescent IL can be used [103]. Here, after rinsing the mouth with the liquid complex, the dyes will fill all possible cracks and, upon illumination, will reveal the location and size of the cracks.…”

In craniofacial research and routine dental clinical procedures, multifunctional materials with antimicrobial properties are in constant demand. Ionic liquids (ILs) are one such multifunctional intelligent material. Over the last three decades, ILs have been explored for different biomedical applications due to their unique physical and chemical properties, high task specificity, and sustainability. Their stable physical and chemical characteristics and extremely low vapor pressure make them suitable for various applications. Their unique properties, such as density, viscosity, and hydrophilicity/hydrophobicity, may provide higher performance as a potential dental material. ILs have functionalities for optimizing dental implants, infiltrate materials, oral hygiene maintenance products, and restorative materials. They also serve as sensors for dental chairside usage to detect oral cancer, periodontal lesions, breath-based sobriety, and dental hard tissue defects. With further optimization, ILs might also make vital contributions to craniofacial regeneration, oral hygiene maintenance, oral disease prevention, and antimicrobial materials. This review explores the different advantages and properties of ILs as possible dental material.

“…Gan found that due to the tunability of ILs, a new fluorescent IL probe [P66614][HQS] was designed, synthesised and characterised owing to the introduction of specific fluorophores into ILs. The new fluorescent IL probe [P66614][HQS] has a unique performance as a chemical sensor for the detection of Al 3+ in aqueous solutions [ 27 ]. Second, fluorescent properties are used to judge the functional groups and structures of new ILs [ 28 , 29 ].…”

“…First, an anion-functionalized IL probe was screened with a large conjugated plane and rich π-electrons for PQ detection. This anion-functionalized probe could have a strong electrostatic attraction with the cationic PQ, and this “enrichment” can exclude the vast majority of uncharged pesticides and narrow the distance between the PQ and the probe, providing a prerequisite for specific and rapid detection of PQ. , Immediately after, fluorescein was selected as a fluorophore of the probe to offer an optical signal change due to high fluorescence efficiency, rich conjugated π-electrons, and vivid colors. , Its fluorescence would be quenched after addition with PQ because the electron-poor π-cloud pyridine aromatic ring of PQ is prone to electron transfer and π–π stacking. − In addition, the charge effect and signal amplification of such ILs also efficiently made up for the lack of specificity and sensitivity of the existing optical probes .

Detection of pesticide paraquat (PQ) is of considerable significance to ensure food safety, and its rapid and on-site detection is still a challenge. Aimed at the ion characteristics of PQ, an “enrichment and detection” strategy was proposed to improve the sensitivity through electrostatic attractions, and the ion characteristic of probes was adopted to increase the portability through avoiding aggregation-caused quenching effects in the paper strips. Herein, a novel anion-functionalized ionic liquid (IL) probe with a large conjugated plane and rich π-electrons ([Fluo][P66614]2) was designed as a fluorescent and colorimetric dual-channel probe to sensitively and rapidly detect trace amounts of PQ in vegetables and the environment. The proposed probe exhibited good linearity with a detection limit of 64.0 nM in the PQ concentration range of 0.3–7.0 μM (fluorometry) and 0.1 μM in that of 0.1–8.0 μM (colorimetry), respectively. In addition, it displayed a rapid fluorescence quenching response from green to dark (<5 s) and excellent anti-interference (among 23 other pesticides) due to dual effects of electrostatic attraction and π–π stacking. Most importantly, the lipophilic IL probe could be applied in real vegetables and environmental samples with a satisfying recovery rate of 98–103% and assembled into a handy paper strip that achieved the visual semiquantitative detection of PQ. This ionic probe provides a feasible approach for rapidly and conveniently detecting PQ for ensuring agricultural and food safety and opens a new avenue to detect ion-responsive analytes in real complex samples by an “enrichment and detection” strategy.
