The effects of metals (cadmium, zinc, copper and nickel in a mixture) on biosorption and biodegradation of five mixed polycyclic aromatic hydrocarbons (PAHs), namely fluorene (FLU), phenanthrene (PHE), fluoranthrene (FLA), pyrene (PYR) and benzo[a]pyrene (BAP), by Selenastrum capricornutum were investigated. Exposure to metals significantly influenced the(More)
Novel magnetic multi-walled carbon nanotubes@Fe(3)O(4) molecularly imprinted polymers (MWNTs@Fe(3)O(4)-MIPs) intended for bovine serum albumin (BSA) recognition were successfully developed. The MWNTs@Fe(3)O(4)-MIPs were characterized with scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). Scanning electron microscopy(More)
Pyruvate kinase (PK) catalyzes the final step of glycolysis. There are few reports on the role of PK in rice. Here, we identified a novel rice dwarf mutant, designated as ospk1, showing dwarfism, panicle enclosure, reduced seed set, and outgrowth of axillary buds from culm nodes. Sequence analyses of 5′-RACE indicated that a single T-DNA was inserted in the(More)
A new surface imprinting technique was reported to synthesize multi-walled carbon nanotubes-molecularly imprinted polymers (MWNTs-MIPs) using erythromycin as the template, acryloyl-β-cyclodextrin (acryloyl-β-CD) and methacrylic acid (MAA) as the binary functional monomers. The MWNTs-MIPs were characterized by transmission electron microscopy (TEM), scanning(More)
Shigella and Salmonella are frequently isolated from various food samples and can cause human gastroenteritis. Here, a novel multiple endonuclease restriction real-time loop-mediated isothermal amplification technology (MERT-LAMP) were successfully established and validated for simultaneous detection of Shigella strains and Salmonella strains in only a(More)
A novel sensitive and selective imprinted electrochemical sensor was successfully constructed for the direct detection of L-histidine by combination of a molecular imprinting film and multi-walled carbon nanotubes (MWNTs). The sensor was fabricated onto an indium tin oxide (ITO) electrode via stepwise modification of MWNTs and a thin film of molecularly(More)
Herein, a novel imprinted sol-gel electrochemical sensor based on multi-walled carbon nanotubes (MWNTs) doped with chitosan film on a carbon electrode has been developed. Prior to doped, the MWNTs have been decorated with Fe(3)O(4) nanoparticles which have been coated uniformly with SiO(2) layer. The characterization of imprinted sensor has been carried out(More)
A core-shell complex-imprinted polymer (CIP) was synthesized and evaluated for selective extraction of melamine from dairy products. The CIP synthesis based on surface modification of home-made silicon microspheres was conducted via a metal complex as functional monomer, ethylene glycol dimethylacrylate as cross-link and melamine as template. The resulting(More)
The aquatic environment often contains different groups of contaminants, but their combined toxicity on microalgae has seldom been reported. The present study compared the toxic effects of combined mixed polycyclic aromatic hydrocarbons (PAHs) and heavy metals on growth and antioxidant responses of free and immobilized microalga, Selenastrum capricornutum.(More)
Here, a novel model of loop-mediated isothermal amplification (LAMP), termed multiple inner primers-LAMP (MIP-LAMP), was devised and successfully applied to detect Listeria monocytogenes. A set of 10 specific MIP-LAMP primers, which recognized 14 different regions of target gene, was designed to target a sequence in the hlyA gene. The MIP-LAMP assay(More)
