“…S1B (ESI†) shows the fluorescence intensity plotted against TX100 concentration, which is known as the determination of CMC by a fluorescence method. 30 The CMC of TX100 calculated from the intersection of the two approximate straight lines in Fig. S1B (ESI†) was 247 μM, which is in close agreement with the literature value.…”

“…S1B and D (ESI †) shows that the slope of the approximate curve before micelle aggregation is about 70 times higher for Tw80 than for TX100. The slope of this line is considered to indicate the magnitude of affinity between the monomer surfactant and the fluorescent probe, 30 and it can be seen that Tw80 has a higher slope, or affinity for ANS, than TX100. As shown above, k a is more than five times larger for Tw80 than for TX100.…”

“…When the solution reaches the critical micelle concentration, the surface tension of the solution is reduced to the lowest value. When the surfactant concentration is increased, the surface tension of the solution is no longer reduced, but a large number of micelles are formed, thus forming micelles . Blank micelles were prepared according to the final prescription, and then we plotted with lgC as the X -axis and the fluorescence intensity ratio at 372 and 384 nm as the Y -axis.…”

Objective: Schisandrin B (Sch B) is a bioactive dibenzocyclooctadiene derizative that is prevalent in the fruit of Schisandra chinensis. Numerous studies have demonstrated that Sch B has a neuroprotective action by reducing oxidative stress and effectively preventing inflammation. It follows that Sch B is a potential treatment for Alzheimer's disease (AD). However, the drug's solubility, bioavailability, and lower permeability of the blood−brain barrier (BBB) can all reduce its efficacy during the therapy process. Therefore, this study constructed borneolmodified schisandrin B micelles (Bor-Sch B-Ms), which increase brain targeting by accurately delivering medications to the brain, effectively improving bioavailability. High therapeutic efficacy has been achieved at the pathological site. Methods: Bor-Sch B-Ms were prepared using the thin film dispersion approach in this article. On the one hand, to observe the targeting effect of borneol, we constructed a blood−brain barrier (BBB) model in vitro and studied the ability of micelles to cross the BBB. On the other hand, the distribution of micelle drugs and their related pharmacological effects on neuroinflammation, oxidative stress, and neuronal damage were studied through in vivo administration in mice. Results: In vitro studies have demonstrated that the drug uptake of bEnd.3 cells was increased by the borneol alteration on the surface of the nano micelles, implying that Bor-Sch B-Ms can promote the therapeutic effect of N 2 a cells. This could result in more medicines entering the BBB. In addition, in vivo studies revealed that the distribution and circulation time of medications in the brain tissue were significantly higher than those in other groups, making it more suitable for the treatment of central nervous system diseases. Conclusion: As a novel nanodrug delivery system, borneol modified schisandrin B micelles have promising research prospects in the treatment of Alzheimer's disease.

“…Surfactants are widely used in industrial and household products, such as detergents, cosmetics, and agricultural and oilfield applications. Monitoring the levels of surfactants in environmental samples can provide information on the extent of contamination and guide interventions to reduce the impact of surfactants on the environment 32 . Molecule 5, which contains dimethylaniline and a hydroxyl group, exhibits AIE behavior and has been used to study the effect of added surfactant on aggregation-induced emission (Figure 4).…”

At lower concentrations of the surfactant, AIE emission is preserved, while at higher concentrations, the loss of AIE emission is observed, which is correlated with micellization.…”

In recent years, there has been considerable interest in cyanostilbenes due to their unique photophysical properties. The compounds emit light when aggregating, commonly called aggregation-induced emission (AIE). This remarkable feature makes cyanostilbenes ideal for various sensing applications, especially in aqueous environments. The detection of various analytes, such as metal ions and nitroaromatic compounds, has been accomplished using these compounds through various sensing mechanisms from chelation-enhanced fluorescence to fluorescence quenching. Furthermore, cyanostilbenes have shown great promise in biological imaging applications and have been employed for intracellular imaging, tracking, and targeting of sub-cellular organelles. The development and utilization of cyanostilbenes can significantly impact advancing sensing and imaging technologies in both analytical and biological fields. This potential stems from the unique properties of cyanostilbenes, such as their AIE characteristic, which sets them apart from other compounds and makes them highly useful for various applications. Further exploration and development of cyanostilbenes could lead to the creation of novel sensing and imaging technologies with wide-ranging applications in both academic and industrial settings
