Herein, an electrochemical (EC)–photoelectrochemical (PEC) dual-mode biosensor was constructed for cytokeratin 19 fragment 21-1 (CYFRA21-1) assay based on the dual-signaling ratiometric strategy and "on–off–on" PEC method. The indium tin oxide (ITO) electrode modified by 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA)@C60 gold nanoparticles (Au NPs), double-stranded DNA composed of thiol/methylene blue (MB)-labeled single-stranded (ssDNA) (S0-MB) antibody/ferrocene (Fc)-labeled ssDNA...
Highly sensitive and selective microRNA (miRNA) assay is of great significance for disease diagnosis therapy. Herein, a magnetic-assisted electrochemistry (EC)–photoelectrochemistry (PEC) dual-mode biosensing platform was developed miRNA-210 detection based on dual-signaling EC photocurrent-polarity-switching PEC strategies. Porous magnetic Fe3O4 octahedra with large surface area were synthesized by calcining Fe-based metal–organic frameworks. Subsequently, the photoelectric materials...
Mercury ion (Hg2+) is one of the most harmful heavy metal ions with greatest impact on public health. Herein, based excellent catalytic activity toward 3,3′,5,5′-tetramethylbenzidine (TMB) and strong photocurrent-polarity-switching ability to SnS2 photoanode split G-quadruplex–hemin complex, magnetic NiCo2O4@SiO2–NH2 sphere-assisted colorimetric photoelectrochemical (PEC) dual-mode sensing platform was developed for Hg2+ assay. First, amino-labelled single-stranded DNA1 (S1) immobilized then...
The self-powered sensors have attracted widespread attention in the analysis field due to a huge demand of point-of-care testing (POCT) early diagnosis diseases. However, output voltage reported is always small, resulting narrow linear detection range and low assay sensitivity. Herein, photoelectrochemical (PEC) sensor with zinc–air batteries as power source was developed for activity protein tyrosine phosphatase 1B (PTP1B) based on perovskite quantum dots encapsulated vinyl-functionalized...

As the most important serum biomarker for prostate cancer, sensitive and accurate detection of prostate-specific antigen (PSA) is great reference value clinical diagnosis treatment cancer. Herein, a peptide cleavage-mediated environmentally friendly photocurrent polarity switching system was developed ultrasensitive highly selective PSA based on efficiently silver indium sulfide nanoparticles (AgInS2 NPs)-coated tin oxide (ITO) electrode by amino-functionalized CuO cubes (NH2-CuO). The...
Water pollution presents a significant environmental concern on earth. Herein, due to the serious harmfulness of arsenate [As(V)], an iron phthalocyanine (FePc)-induced switchable photocurrent-polarity platform was developed for highly selective assay As(V). First, magnetic Co3O4–Fe3O4 cubes were obtained by calcination CoFe Prussian blue analogue and then functionalized with oligonucleotide (S1). In presence As(V), S1 could be released based stronger affinity between As(V) cubes. After...
Abstract Downwelling favorable winds off the west Greenland coast induce onshore Ekman transport, thereby limiting freshwater influx into interior of Labrador Sea. Although eddies shed by West Current (WGC) provide an important source, role downwelling in eddy formation is still largely unknown. Using output a very-high resolution (1/60°) model, combined with idealized model experiments, we find that push denser water over lighter water, which leads to gain Available Potential Energy (APE)....
Abstract A reasonable representation of crop phenology and biophysical processes in land surface models is necessary to accurately simulate energy, water, carbon budgets at the field, regional, global scales. However, evaluation that can be coupled Earth system relatively rare. Here we evaluated two such (CLM4‐Crop CLM3.5‐CornSoy), both implemented within Community Land Model (CLM) framework, AmeriFlux corn‐soybean sites assess their ability phenology, fluxes. Our results indicated accuracy...
Abstract. Increasing atmospheric humidity and convective precipitation over land provide evidence of intensification the hydrologic cycle – an expected response to surface warming. The extent which terrestrial ecosystems modulate these factors is important understand feedbacks in climate system. We measured oxygen hydrogen isotope composition water vapor at a very tall tower (185 m) upper Midwest, United States, diagnose sources, transport, fractionation planetary boundary layer (PBL) 3-year...
Abstract Nitrous oxide (N 2 O) emissions within the US Corn Belt have been previously estimated to be 200–900% larger than predictions from emission inventories, implying that one or more source categories in bottom‐up approaches are underestimated. Here we interpret hourly N O concentrations measured during 2010 and 2011 at a tall tower using time‐inverted transport model scale factor Bayesian inverse method simultaneously constrain direct indirect agricultural emissions. The optimization...
Abstract The effects of dams on carbon dioxide (CO 2 ) fluxes in downstream lakes remain elusive. Here we combined eddy covariance observations and random forest models to examine multi‐decadal variations CO the Poyang Lake, largest freshwater lake China, quantified contribution Three Gorges Dam (TGD), world's hydraulic project. We found fluctuated between source sink 1961–2016, tended be post‐TGD period (2003–2016) when vegetation expanded early spatially due declining water level. TGD can...
Based on DNAzyme-induced disassembly of the “Z-scheme” TiO<sub>2</sub>/Au/CdS QDs system, a facile and sensitive photoelectrochemical biosensor was developed for lead ion assay.
Abstract Anthropogenic carbon dioxide (CO 2 ) emissions dominate the atmospheric greenhouse gas radiative forcing budget. However, these are poorly constrained at regional (10 –10 6 km and seasonal scales. Here we use a combination of tall tower CO mixing ratio isotope observations inverse modeling techniques to constrain anthropogenic within highly heterogeneous agricultural landscape near Saint Paul, Minnesota, in Upper Midwestern United States. The analyses indicate that contributed 6.6,...
