Abstract

Microemulsions (MEs) comprising of cholinium dodecylbenzene sulphonate Cho[DBS], a bio-based ionic liquid surfactant as an emulsifier, hydrophobic deep eutectic solvent (HDES) as nonpolar phase, and water as a polar component are constructed. Negative value of ∆G estimated from isothermal titration calorimetry (ITC) plots indicate spontaneous aggregation of Cho[DBS] both in water and HDES. The aggregates of Cho[DBS] in HDES and water show the critical micellar concentration (cmc) of ≈4.26 and ≈2.4 mMm, respectively. Cho[DBS] shows a better emulsifying capacity with a high monophasic region in the ternary phase diagram. MEs are utilized as nanoreactors for the sustainable synthesis of nano-sized fluorescent carbon nanoparticles (FCNPs) with precise control over size and morphology. FCNPs are characterized using PXRD, Raman, XPS, HR-TEM, UV–vis, and Fluorescence spectroscopic techniques. FCNPs exhibited remarkable properties viz. adjustable luminescence, good solubility, and biocompatibility. FCNPs are applied for fluorometric sensing of nitroaromatic compounds (NACs) and antibiotics through a quenching response originating from the inner filter effect, with a fast response nanomolar detection, and are found highly selective toward TNP (NAC), NFT, and NZF (antibiotics).

利用微乳液中的深共晶溶剂进行环保型荧光碳纳米粒子合成及其对抗生素和硝基芳香族化合物的高灵敏传感
本研究构建了由十二烷基苯磺酸胆碱 Cho[DBS](一种生物基离子液体表面活性剂,用作乳化剂)、疏水性深共晶溶剂(HDES)(用作非极性相)和水(用作极性组分)组成的微乳液(MEs)。从等温滴定量热仪(ITC)图中估算出的 ∆G 负值表明 Cho[DBS] 在水和 HDES 中都会自发聚集。Cho[DBS]在 HDES 和水中的临界胶束浓度(cmc)分别为≈4.26 和≈2.4 mMm。Cho[DBS]具有更好的乳化能力,在三元相图中具有较高的单相区。利用 ME 作为纳米反应器,可持续合成纳米级荧光碳纳米粒子(FCNPs),并精确控制其尺寸和形态。利用 PXRD、拉曼、XPS、HR-TEM、UV-vis 和荧光光谱技术对 FCNPs 进行了表征。FCNPs 表现出显著的特性,即可调发光、良好的溶解性和生物相容性。FCNPs 可用于硝基芳香族化合物(NAC)和抗生素的荧光传感,其淬灭反应源于内滤光片效应,具有纳摩尔级的快速检测响应,并且对 TNP(NAC)、NFT 和 NZF(抗生素)具有高度选择性。
