    Abstract An easy and fluorescent strategy is developed for the detection of cancer cells and cellular imaging. This assay relies on the quenching of Ru complex toward quantum dots (QDs) and the amplification of hybridization chain reaction (HCR). In the presence of target cancer cells, folate-modified single-stranded DNA (F-DNA) links on the cell membranes through high affinity of folate and receptors. Hybridization reaction between pre-prepared HCR products and F-DNA immobilizes HCR products on the surfaces of target cells, resulting in large amount of Ru complex into HCR products and strong red fluorescence on the surfaces of target cells. Meanwhile, QDs-Ru complex assembling dyads in supernate are reduced, leading to the fluorescence restoration of QDs. Taking human cells lines HeLa as a model analyst, the linear response for HeLa cells in a concentration range from 100 to 10 5 cells mL −1 is obtained with a detection limit of 100 cells mL −1 . The specificity of this assay for the detection of cancer cells is demonstrated against several cell competitors. Additionally, this assay is successfully applied to inhibitor screening for cancer cells in combination with cellular imaging, demonstrating the university of this design. Highlights A new fluorescent assay for cancer cell detection and cellular imaging is developed. The strategy relies on the quenching of Ru complex toward QDs and HCR amplification. The assay demonstrates excellent specificity in FRs-positive cancer cells against several cell competitors. This assay is also successfully applied to inhibitor screening for cancer cells.

    Abstract Fast and accurate detection of aqueous mercury(II) ions is of significant importance as it raises serious risks for human health and the environment. Here, we report a photoelectrochemical determination of mercury(II) ions with nickel oxyhydroxide-functionalized n-silicon photoanodes at zero working voltage. Based on the catalysis effect of Hg(II) ions on the photocurrent of the catechol probe, a simple and sensitive photoelectrochemical sensor was constructed for Hg(II) ions detection in purified drinking waters (PW1, PW2 and PW3). The photocurrents show good response after the solution containing Hg(II) ions was added to the photoelectrochemically active catechol solution. Under the optimized conditions, the increase of photocurrent is proportional to the Hg(II) ions concentration, the linear dynamic range is observed from 10nM to 450nM with the detection limits of 5.4, 7.2 and 5.2nM in PW1, PW2 and PW3, respectively. Our work suggests that the two electrodes structures are promising for low-cost, portable, real-time, heavy metal ion detectors. Highlights A novel photoelectrochemical cell has been used for determination of Hg(II) ions. We use a two-electrode system without applied voltage for Hg(II) ion detection. This system has successfully averted from inconvenient reference electrode. Mild media used for photocurrent measurement provides low noise of background. The method is promising for simple, low-cost, portable, real-time, heavy metal ions detectors.

    초록

    Abstract Analytical applications of paper-based microfluidic devices, receive much attention and have been heavily investigated in the last few years. Liquid movement in the body of the paper brings the idea of paper-based flow injection analysis (FIA) developed according to lab-on-paper (LOP) concept. In this approach, paper patterned with hydrophobic borders playing the role of channels in FIA system. The channel is connected from one side with an unlimited source of the liquid carrier and from the other side with sorbent pad, which ensures constant and a continued flow of fluid along the channel. Microliter volumes of standards, consecutively placed directly on the paper surface are moving towards detection zone. The developed prototype of LOP-FIA system was tested with the dedicated optoelectronic detector, compatible with a model analyte (bromothymol blue) as well as with Prussian Blue based chemosensitive layer deposited inside a paper channel, playing the role of the prototype of the flow-through optical sensor integrated with LOP. The effects of sorbent/channel type, distance between injection and detection zone and sample volume on the shape of the analytical signal were investigated. Results obtained for sequential sample introduction show satisfactory reproducibility, confirming that paper-based microfluidic FIA without conventional tubing, pumps and valves, exploring merits of LOP concept only, is possible. Highlights Channel network made of paper can be a equivalent of Flow Injection Analysis manifold. Architecture of paper channels allows liquid speed manipulation. Repeated sample introduction manifests by peak-shaped signals. Pump-less paper analytical flow injection system with PB sensor has been demonstrated.

    Abstract The rGO/ZnSnO 3 composites have been elaborately synthesized by a facile solution-based self-assembly synthesis method at low temperature. The structure, morphology, thermal stability, composition and specific surface area of composite were characterized by XRD, SEM, TG, XPS and BET analysis, respectively. The sensing experiments show that the sensor based on 3wt% rGO composite not only exhibits high sensitivity (low limit of detection), excellent selectivity and linearity relationship between responses and formaldehyde concentration from 1 to 10ppm, but also exhibits fast response and recovery at operating temperature of 103°C. The enhanced sensing mechanism of the hybrid to formaldehyde was discussed in detail, which can mainly be ascribed to the large specific surface area for gas adsorption, porous channels for gas diffusion, the fast carrier transport benefited from rGO and the formation of heterojunction at the interface between the rGO and ZnSnO 3 . Highlights rGO/ZnSnO 3 nanocomposites were synthesized by solution-based self-assembly process. The 3wt% rGO/ZnSnO 3 shows high sensitivity, good selectivity and rapid response-recovery. The mechanism of enhancing sensing is ascribed to large surface and formation of heterojunction. Graphical abstract The rGO/ZnSnO 3 composite have been synthesized by a modified Hummers method and a facile solution-based self-assembly synthesis method at low temperature. It shows good formaldehyde sensing performance which is ascribed to the large surface area, a mass of active sites and the formation of heterojunction in the interface between rGO and ZnSnO 3 .

    Abstract Virus detection is often performed using antibody-based and polymerase chain reaction-based techniques. Such methods have major deficiencies, caused by time-consuming and labor-intensive incubation and purification steps. In this contribution, a novel SERS substrate for qualitative virus detection was developed and described. The substrate is composed of a thin silver film with folded surface structure containing pore-like nanoscale cavities and indentations, deposited on mica substrate by electron beam physical vapor deposition method. Pore-like structures are semi-regularly arrayed, with a rough surface in between, allowing for SERS activity, and their size and periodicity can be manipulated in the manufacturing process. It was speculated that viral particles could be trapped in these structures and would generate easily detectable enhanced Raman signals. The SERS substrate was tested against detection of four virus species – rabbit myxomatosis virus, canine distemper virus, tobacco mosaic virus and potato virus X. Specific spectra were obtained and analyzed for each virus. Data analysis demonstrated successful differentiation between tested species. The reported results demonstrate that novel SERS substrate is suitable for detection and identification of viral particles. Highlights A novel silver SERS substrate was fabricated by EBPVD method and characterized. The substrate contains nanoscale pore-like structures and cavities, separated by rough surface. The novel SERS substrate was proposed for detection of viruses and tested, SERS spectra of four viruses were obtained and processed. Data analysis showed complete differentiation between viral species based on their spectral data. Graphical abstract [DISPLAY OMISSION]

    Abstract A facile approach for the electrochemical determination and catalytic degradation of sunset yellow (SY) by using palladium-ruthenium nanoparticles incorporated carbon aerogel (Pd-Ru/CA) as catalyst is reported. The Pd-Ru/CA nanocomposite was prepared by sol-gel polymerization invoking the evaporation induced self-assembly (EISA) method and was characterized by various techniques such as XRD, SEM/TEM, N 2 physisorption/chemisorption, thermal analysis, and Raman, XPS, and EDS spectroscopies. The Pd-Ru/CA modified screen printed carbon electrode (SPCE) was found to show excellent performances for electrochemical detection and catalytic degradation of SY, surpassing the conventional HPLC method even in real samples. Effects of key experimental parameters such as type and pH of supporting electrolyte, and dye and interference concentrations on selectivity of the sensor during electrochemical detections were thoroughly assessed by CV and DPV methods The Pd-Ru/CA modified SPCE revealed excellent limit of detection (LOD) and analytical sensitivity of 7.1nM and 3.571μA μM −1 cm −2 , respectively. Moreover, as verified by UV–vis spectroscopy, the Pd-Ru/CA nanocomposite exhibited an extraordinary performance for catalytic degradation of SY with a pseudo-first order rate constant ( k ) of ca. 0.295s −1 , making the proposed nanomaterial a suitable platform for prospective photo- and electro-catalytic applications. Highlights Highly dispersed Pd-Ru on carbon aerogel as an efficient electrochemical sensing of SY. Exploring the potential electrocatalytic and catalytic applications of Pd-Ru/CA materials is a fascinating challenge. We believe that this work will open up a new route for sensing SY in food samples. The monitoring of synthetic colorants in foods is very important due to their potential toxicity. Greatly-enhanced degradation activity toward SY in the presence of Pd-Ru/CA catalyst. Graphical abstract The Pd-Ru/CA nanocomposites are promising materials for catalytic and electrocatalytic reactions It also open up new opportunities for practical and sustainable applications.

    Abstract An electrogenerated chemiluminescence (ECL) biosensor array for the individual and simultaneous detection of multiple biomarkers has been developed at first time on the basis of the aptamer-based biosensor incorporating a versatile signal probe. As principle-of-proof, the acute myocardial infarction (AMI) biomarkers, myoglobin(Myo), cardiac troponin I(cTnI) and cardiac troponin T(cTnT) were chosen as model analytes. The biosensor array was fabricated by self-assembling thiolated specific ssDNA aptamers on the surface of gold electrodes, respectively. After each target analyte was bound to the capture probes and then to each corresponding biotinylated antibody, and finally to the versatile ECL signal probe, ECL signals were recorded using PMT or CCD as a detector. For PMT model, the developed method showed extremely low detection limits for 0.30 ng/mL cTnT, 31 pg/mL Myo, 0.79 pg/mL cTnI. For ECL image model, a biosensor array containing three target biosensors and a control biosensor was found to be highly sensitive, no cross-talking, and accurate towards simultaneous detection of the AMI biomarkers. This work demonstrates that the aptamer-based biosensor array with a versatile signal probe is a promising for ECL simultaneous detection of multi-biomarkers. Highlights A sensor array for ECL image detection of multi-biomarkers in-one-run was developed. A sensor array containing three different biosensors was designed and characterized. Thiothlated specific aptamers were used as the capture probes. A versatile signal probe is promising for the detection of multi-biomarkers. The developed method was high sensitive, no cross-talking, and accurate.

    Abstract A Zn 3 L 2 -type metal organic aggregate featuring “six leaf windmill” shaped double cages constructed from a semi-rigid tripodal carboxyl acid ligand H 3 TCPB (1,3,5-tri(4-carboxyphenoxy) benzene) exhibits sensitive luminescent response toward DMA with obvious intensity enhancement and red-shift. During the procedure, the host-gust interaction was supported by single-crystal-to-single-crystal transformation involving drastic conformational change of the molecular host upon μ 2 -bridging H 2 O release and the sensing mechanism was also discussed through theoretical calculations from charge separation hypothesis perspective. The DMA post-modified result of crystal transforming reveals high selective and effective naked eye reversible recognition for Co 2+ ions through the dynamic and static quenching mechanisms. Moreover, the visual luminescent test paper was realized for potential application in concerns of the biology and environment. Highlights A windmill-shaped Zn 3 L 2 cage was synthesized and exhibits effective and fast luminescent response to DMA with crystal transformation involving drastic conformational change. The crystal transform result with DMA post-modification could be served as naked eye quenching sensor for Co 2+ ions with high selectivity and efficiency.
