Abstract A nanostructured multicatalyst system consisting of Fe 3 O 4 magnetic nanoparticles (MNPs) as peroxidase mimetics and an oxidative enzyme entrapped in large‐pore‐sized mesoporous silica has been developed for convenient colorimetric detection biologically important target molecules. The construction the nanocomposites begins with incorporation MNPs on walls mesocellular pores by impregnating Fe(NO ) ⋅9 H 2 O, followed immobilization enzymes. Glutaraldehyde crosslinking was employed...
The potential use of Ligilactobacillus salivarius-derived bacteriocin for the control L. monocytogenes was investigated. purpose study to explore antibacterial action mode crude C2-1 from salivarius against Listeria CICC 21633. inhibition zone diameter 27.82 ± 0.3 mm 21633, and minimum inhibitory concentration (MIC) C2-1was 13.98 μg/mL. Bacteriocin significantly inhibited normal growth CICC21633, is sensitive proteinase K, trypsin, pepsin, has good thermal stability acid tolerance. 21633...
Chiral biomolecules conjugated with silver nanoparticles were investigated by circular dichroism (CD) spectroscopy. Silver prepared the citrate reduction method and characterized UV spectroscopy TEM. Conjugation of thiol group-containing biomolecules, such as cysteine, glutathione penicillamine, resulted in generation new characteristic CD signals region 240–400 nm, whereas no signal changes found lysine or glutamine. Association through hydrogen bonding among is considered to be essential...
A novel DNAzyme molecular beacon (DNAzymeMB) strategy was developed for target-induced signal-amplifying colorimetric detection of target nucleic acids. The DNAzymeMB, which exhibits peroxidase activity in its free hairpin structure, engineered to form a catalytically inactive hybrid through hybridization with blocker DNA. presence DNA leads dissociation the DNAzymeMB from This process results recovery active can catalyze reaction that signals In addition, primer rationally designed anneal...
This genus contains both phototrophs and nonphototrophic members. Here, we present a high-quality complete genome of the strain CHu59-6-5T, isolated from freshwater sediment. The circular chromosome (4.39 Mbp) CHu59-6-5T has 64.4% G+C content 4240 genes, which total 3918 genes (92.4%) were functionally assigned to COG (clusters orthologous groups) database. Functional for denitrification (narGHJI, nirK qnor) identified on genomes except N2O reductase (nos) final step denitrification. Genes...
A colorimetric method for quantification of galactose, which utilizes a nanostructured multi-catalyst system consisting Fe(3)O(4) magnetic nanoparticles (MNPs) and galactose oxidase (Gal Ox) simultaneously entrapped in large pore sized mesocellular silica, is described. Gal Ox, immobilized silica matrix, promotes reaction to generate H(2)O(2) that subsequently activates MNPs mesopores convert substrate into colored product. By using this method, can be specifically detected. Along with...
A label-free fluorescence immunoassay system relying on from the dianionic form of ochratoxin (OTA) in OTA/anti-OTA complex was developed. With an optimized system, can be used to detect OTA a highly specific manner with detection limit 0.5 ng mL−1.
A label-free, direct and noncompetitive homogeneous immunoassay, in which ochratoxin (OTA) coupled with the anti-OTA antibody participates fluorescence resonance energy transfer (FRET), was developed for detection of OTA great specificity a limit 1 ng mL(-1).
The operation of an electrochemical real-time PCR system, based on intercalative binding methylene blue (MB) with dsDNA, has been demonstrated. was performed a fabricated electrode-patterned glass chip containing MB while recording the cathodic current peak by measuring square wave voltammogram (SWV). signal found to decrease increase in cycle number. This phenomenon be mainly consequence lower apparent diffusion rate MB-DNA complex (Db = 6.82 × 10−6 cm2 s−1 612 bp dsDNA) as compared that...
An ultrasensitive DNAzyme-based colorimetric DNA detection strategy was developed by utilizing gold nanoparticles modified with both peroxidase-mimicking DNAzymes and capture DNAs magnetic another DNAs, a limit for model Chlamydia gene of 50 fM.
A gold nanorod (GNR) based LSPR sensor has been developed for label-free detection of C-reactive protein (CRP). The utilizes a single chain variable fragment (scFv) as receptor to bind CRP. results this effort show that CRP in human serum can be quantitatively detected at lower than 1 ng mL−1.
The K-shell ionization cross sections of Ni and Cr by electron impact have been measured. In the measurements thin targets with a thick substrate were used. influence reflected electrons from on has corrected means detailed calculation transport. By comparison it is shown that measurement data section are in good agreement existing experimental data.
A free-living Bradyrhizobium strain isolated from a contaminated sediment sample collected at water depth of 4 m the Hongze Lake in China was characterized. Phylogenetic investigation 16S rRNA gene, concatenated housekeeping gene sequences, and phylogenomic analysis placed this lineage distinct all previously described species. The sequence similarities genes support its distinctiveness with type strains named complete genome S12-14-2 consists single chromosome size 7.3M. lacks both...
