The deterioration of alpine grassland has great impact on ecosystem services in the region Qinghai-Tibetan Plateau. However, effect degradation and consequence economic loss still remains a mystery. So, this study, we assessed four types following Millennium Ecosystem Assessment classification, along gradient. Five sites at different levels were investigated Guoluo Prefecture Qinghai Province, China. species composition, aboveground biomass, soil total organic carbon (TOC), nitrogen (TN)...
A highly sensitive and selective photoelectrochemical (PEC) biosensor for Hg(2+) detection was developed on the basis of synergistic effect exciton energy transfer (EET) between CdS quantum dots (QDs) Au nanoparticles (NPs) coupled with sensitization rhodamine 123 (Rh123) signal amplification. First, TiO2/CdS hybrid structure obtained by depositing QDs TiO2 film employed as a matrix immobilizing probe DNA (pDNA). Next, Rh123 introduced into pDNA terminal, then NP labeled target (Au-tDNA)...
MicroRNAs (miRNAs) have emerged as new candidates diagnostic and prognostic biomarkers for the detection of a wide variety cancers; thus, sensitive selective microRNAs is significant early-phase cancer diagnosis disease prevention. A novel simple electrochemical miRNA biosensor was developed using Cd2+-modified titanium phosphate nanoparticles signal unit, two DNA capture probes, Ru(NH3)63+ electron transfer mediator. Large quantities cadmium ions were mounted in spheres to output signal....
Abstract Field surveys and experiment analyses were applied to detect the relationships between plant diversity, community biomass soil resources at different degradation successional stages in headwater region of three rivers an alpine meadow. The chronosequence approach (space‐for‐time substitution) is a viable tool for obtaining integrated information within studies. experimental plots located Guoluo area, which part source Yangtze Yellow Rivers. results showed not only that quantities...
A novel and facile strategy for the fabrication of aptamer-based adenosine 5′-triphosphate (ATP) biosensor was developed by a quantum dot (QD) electrochemiluminescence (ECL) technique. Different from existing strategies development aptasensors based on electrochemical, fluorescent or other methods, proposed here is essentially aptamer–ATP specific affinity rules Watson–Crick base pairing. After thiol modified anti-ATP probes were immobilized onto pretreated Au electrode, electrode incubated...
Filter paper strips combined with screen-printed carbon electrodes (SPCE) were used in the assembly of a microfluidic device for detecting Pb(II) and Cd(II) aqueous samples. The portable (with direct electrochemical detection) was tested quantification multiple analytes (Pb(II) Cd(II)) contaminated samples without pretreatment. Square wave anodic stripping voltammetric (SWASV) signal greatly enhanced displayed excellent analytical performance detection (from 0 to 100 ppb) low limit 2.0 2.3...
Grassland degradation is one of the worldwide ecological problems. The objective this study was to assess above‐ and belowground response an alpine grassland along gradient in headwater areas Qinghai‐Tibetan Plateau. Results showed that aboveground biomass, cover, high quality herbage percentage presented a decreasing trend gradient. But, species number, diversity, evenness maximum value moderate degraded grassland, minimum appeared extreme grassland. Similarity index between original...
Sonoelectrochemical technique was successfully used to fabricate alloy–graphene nanocomposites. It not only provides a simple way synthesize alloy nanoparticles, but also shows general strategy for fabricating graphene-based nanostructures with anticipated properties. Pd co-electrodeposited Pt at different atomic ratios, and then anchored reduced graphene oxide (RGO) simultaneously in the presence of PDDA. The morphologies structures as-prepared PDDA-RGO-PdPt nanocomposites were extensively...
A multifunctional boron nitride–gold nanocluster composite was fabricated using poly-diallyldimethylammonium chloride as a stabilizer and linker. The as-fabricated could be used fluorescent or an electrochemical label for immunosensing in the sensitive detection of interleukin-6.
