Development of a fluorescent nanoprobe based on an amphiphilic single-benzene-based fluorophore for lipid droplet detection and its practical applications
single benzene-based fluorophore (SBBF). BMeS-Ali consists of hydrophilic (–NH2) and hydrophobic (–C12H25) moieties and exists as a micelle nanostructure in aqueous media. BMeS-Ali has a weak fluorescence, but its emission was dramatically enhanced upon exposure to the LD components such as oleic acids (OA) by reassembling its nano-formulation. BMeS-Ali showed a selective LD staining ability and great

the natural environment due to its high reactivity and toxicity. In this work, we disclosed a new fluorescentprobe for hydrazine detection, utilizing a single benzene-based fluorophore (SBBF). The new hydrazine probe, named HP, reacted explicitly with hydrazine in a short time (<1 min) and had ratiometric emission changes with a large Stokes shift (172 nm). HP also showed high physicochemical stability
肼(N 2 H 4)是一种重要的化学品,广泛应用于各个工业领域。然而,由于肼的高反应性和毒性,接触肼会对人类、动物和自然环境造成严重危害。在这项工作中,我们公开了一种用于肼检测的新型荧光探针,利用单一苯基荧光团(SBBF)。新的肼探针,名为HP,在短时间内(<1 分钟)与肼发生明确反应,并具有较大斯托克斯位移(172 nm)的比率发射变化。生命值还表现出较高的物理化学稳定性,这是在环境条件下实际应用的最关键特性。此外,我们在多种应用中进行了肼检测实验,包括纸条、土壤和液体样品。这项研究提出了一种基于SBBF的新型肼荧光探针,该探针在各个领域具有广泛应用的巨大潜力。
BMeS-p-A succinimidyl ester as a sulfonyl aniline dye labeling reagent
sulfonylaniline-based fluorescent labeling reagent. Introduction of a carboxyl group into the amino group of the sulfonylaniline skeleton was achieved by the ring-opening reaction of β-propiolactone. This small labeling reagent was water-soluble, photostable, solid-state emissive, and suitable for excitation with a versatile 405-nm laser diode, emitting green fluorescence with a large Stokesshift at 527 nm.
5‐bis(methylsulfonyl)‐1,4‐diaminobenzene as a novel architecture for green fluorophores, established based on an effective push–pull system supported by intramolecular hydrogen bonding. This compound demonstrates high fluorescence emission and photostability and is solid‐state emissive, water‐soluble, and solvent‐ and pH‐independent with quantum yields of Φ=0.67 and Stokes shift of 140 nm (in water)
