ABSTRACT A simple, specific and sensitive ultra‐performance liquid chromatography tandem mass spectrometry (UPLC‐MS/MS) method was established validated for simultaneous determination of neochlorogenic acid, chlorogenic cryptochlorogenic acid geniposide in rat plasma using puerarin as an internal standard (IS). Plasma samples were pretreated by a one‐step direct protein precipitation procedure with acetonitrile after acidified little 50 μL plasma. Chromatographic separation performed on...

CO-release induced by near infrared (NIR) light, to which body tissues are relatively transparent, from photoactive CO-releasing molecules (PhotoCORMs) has great significance in exploring the clinical potential of CO. In this work, a novel upconversion nanoparticle-based nanoplatform, UCNPs@SiO2-CORMs, been developed using one-pot reaction. The materials liberate CO under irradiation NIR light. TEM images showed that nanoplatform consisted core-shell structure. On surface were incorporated...

A novel method for increasing the effective nanoparticle loading in electrospun fibers is presented involving electrospinning of polymer blends with suspended ZIF-8 crystals. Initially, varying ratios Matrimid 5218 and poly(ethylene oxide) (PEO) are electrospun, followed by methanol washes to remove PEO form porous nanofibers. After an optimum surface area found from ratio 1:1 Matrimid:PEO weight, metal-organic-framework blend impregnated fibers. removal fibers, it that remains resulting...

The rapid development of nanotechnology and its widespread use have given rise to serious concerns over the potential adverse impacts nanomaterials on Earth’s ecosystems. Among all nanomaterials, silver nanoparticles (AgNPs) are one most extensively used due their excellent antibacterial property. However, toxic mechanism AgNPs in nature is still unclear. One questions under debate whether toxicity associated with size or ions released from AgNPs. In our previous study, a sub-micron hybrid...
