The redox environment between intracellular compartments and extracellular matrix is significantly different, and the cellular redox homeostasis determines many physiological functions. Here, redox‐responsive nanoparticles with aggregation‐induced emission (AIE) characteristic for fluorescence imaging are developed by encapsulation of fluorophore with redox “turn‐on” AIE characteristic, TPE‐MI, into...
This study describes a novel application of ion chromatography coupled with post-column photochemically induced fluorimetry derivatisation in alkaline medium and fluorescence detection (IC-hv-FD) for the determination of neonicotinoid pesticide, thiacloprid. In an aqueous medium, this compound showed fluorescence with an excitation maximum at 236nm and an emission maximum at 353nm. The 10mmol/L NaOH...
We report on a droplet-based, in situ formed tunable cylindrical microlens array in microchannels. The deionized water microlenses are formed via liquid-air interfaces of liquid droplets at T-shaped junctions of octadecyltrichlorosilane (OTS) treated polymerized isobornyl acrylate [poly(IBA)] microchannels, and their focal length can be tuned individually by pneumatic manipulation. These microlenses...
In this study, we examined the effects of exposure to electromagnetic pulse(EMP) on the functional integrity of the BBB and, on the expression of tight junction (TJ) protein (occludin, ZO-1) in rats. Animals were whole body exposed or sham exposed to EMP at 200 kV/m for 400 pulses. The permeability of BBB was examined using Evans Blue (EB) as vascular tracer. The expression of the level of TJ proteins...
