Abstract
Photoresponsive nucleic acids attract growing interest as functional constituents in materials science. Integration of photoisomerizable units into DNA strands provides an ideal handle for the reversible reconfiguration of nucleic acid architectures by light irradiation, triggering changes in the chemical and structural properties of the nanostructures that can be exploited in the development of photoresponsive functional devices such as machines, origami structures and ion channels, as well as environmentally adaptable 'smart' materials including nanoparticle aggregates and hydrogels. Moreover, photoresponsive DNA components allow control over the composition of dynamic supramolecular ensembles that mimic native networks. Beyond this, the modification of nucleic acids with photosensitizer functionality enables these biopolymers to act as scaffolds for spatial organization of electron transfer reactions mimicking natural photosynthesis. This review provides a comprehensive overview of these exciting developments in the design of photoresponsive DNA materials, and showcases a range of applications in catalysis, sensing and drug delivery/release. The key challenges facing the development of the field in the coming years are addressed, and exciting emergent research directions are identified.

Abstract
The Ni(II)-based metallosupramolecular polymer with carboxylic acid groups (polyNi) was synthesized via a 1:1 complexation of Ni(II) salt with (4,4'-(9,9-dihexyl-9H-fluorene-2,7-diyl)bis(pyridine-2,6-dicarboxylic acid) for the first time. The divalent state of Ni(II) in the polymer was confirmed by the X-ray absorption fine structure analysis. Smooth loading of imidazole molecules into polyNi proceeded with the help of the carboxylic acid groups to form the imidazole-loaded polyNi (polyNi-Im). Thermogravimetric analysis of polyNi-Im revealed that approximately three imidazole molecules were incorporated per repeating unit of polyNi. The Fourier transform infrared spectrum of polyNi-Im showed a new peak at 3219 cm-1, which shows an ∼73 cm-1 enhancement to -N-H of pristine imidazole. The peak suggests the formation of an imidazolium cation in the polymer. Powder X-ray diffraction indicated no degradation of the polymer structure during the imidazole loading because the diffraction pattern of polyNi-Im was almost the same as that of polyNi except for the presence of peaks corresponding to the imidazole molecules. Interestingly, the scanning electron microscopy measurement showed a large morphological change to uniform spherical particles by loading imidazole to the polymer. PolyNi-Im exhibited good proton conductivity (1.05 × 10-2 mS/cm) at a high temperature (120 °C), which is around 7 orders of magnitude higher than that of pristine polyNi because of the proton conduction pathway formation along the polymer chains by the incorporated imidazole molecules.

Abstract
Haemophilus influenza (H. influenza) is a gram negative coccobacillus pathogenic microorganism. H. influenza produces beta-lactamases, and it is also able to modify its penicillin-binding proteins, so it has gained resistance to the penicillin family of antibiotics. In this work, a novel sensitive approach was established for the monitoring of H. influenza using DNA based bio-assay. For the first time, specific sequence of thiolated probe of Haemophilus influenza (SH-5'-AAT TTT CCA ACT TTT TCA CCT GCA T-3') was immobilized on the surface of gold (Au) electrode. Square wave voltammetry (SWV) was carried out in toluidine blue (TB) solution for DNA hybridization and targeting of cDNA sequence of Haemophilus influenza. Field scanning electron microscope (FE-SEM) was applied to investigation of the electrode morphology and estimate of particle size. In the optimal conditions, the planned strategy could detect target DNA (5'-ATG CAG GTG AAA AAG TTG GAA AAT T-3') down to 1 ZM with a linear range from 1 μM to 1 ZM. Moreover, engineered geno-assay selectively differentiates the complementary sequence from target sequences with one, double and three base mismatch sequences.

Abstract
The study introduces an analytical platform for the detection of genes or aptamer-ligand complexes by nucleic acid barcode patterns generated by DNA machineries. The DNA machineries consist of nucleic acid scaffolds that include specific recognition sites for the different genes or aptamer-ligand analytes. The binding of the analytes to the scaffolds initiate, in the presence of the nucleotide mixture, a cyclic polymerization/nicking machinery that yields displaced strands of variable lengths. The electrophoretic separation of the resulting strands provides barcode patterns for the specific detection of the different analytes. Mixtures of DNA machineries that yield, upon sensing of different genes (or aptamer ligands), one-, two-, or three-band barcode patterns are described. The combination of nucleic acid scaffolds acting, in the presence of polymerase/nicking enzyme and nucleotide mixture, as DNA machineries, that generate multiband barcode patterns provide an analytical platform for the detection of an individual gene out of many possible genes. The diversity of genes (or other analytes) that can be analyzed by the DNA machineries and the barcode patterned imaging is given by the Pascal's triangle. As a proof-of-concept, the detection of one of six genes, that is, TP53, Werner syndrome, Tay-Sachs normal gene, BRCA1, Tay-Sachs mutant gene, and cystic fibrosis disorder gene by six two-band barcode patterns is demonstrated. The advantages and limitations of the detection of analytes by polymerase/nicking DNA machineries that yield barcode patterns as imaging readout signals are discussed.

Abstract
Developing high proton conducting solid materials is significant in the field of fuel cells. A europium(iii)-based metallo-supramolecular polymer with uncoordinated carboxylic acids (PolyEu-H) was successfully synthesized by modifying the synthesis conditions. The proton conductivity was enhanced with increasing the relative humidity (RH) from 30 to 95% RH. PolyEu-H showed about 104 times higher proton conductivity than the polymer with coordinated carboxylic acids (PolyEu) and about 400 times higher than the polymer without carboxylic acids (PolyEu-2). The proton conductivity of PolyEu-H reached 4.45 × 10−2 S cm−1 at 95% RH and 25 °C and 5.6 × 10−2 S cm−1 at 75 °C. The activation energy, Ea was ultralow (0.04 eV), which indicates proton conduction based on the Grotthuss mechanism. The results indicate that efficient proton conduction occurs through proton channels formed by moisture in PolyEu-H. Developing high proton conducting solid materials is significant in the field of fuel cells. We firstly synthesized europium(iii)-based metallo-supramolecular polymer with uncoordinated carboxylic acids (PolyEu-H), for high proton conduction.![]()

Abstract
Cutting surface-bound optical molecular beacons results in a sandwich-like detection strategy with lower background fluorescence.
For the detection of oligonucleotides a sandwich-like detection strategy has been developed by which the background fluorescence is significantly lowered in comparison with surface-bound molecular beacons. Surface bound optical molecular beacons are DNA hairpin structures comprising a stem and a loop. The end of the stem is modified with a fluorophore and a thiol anchor for chemisorption on gold surfaces. In the closed state the fluorophore is in close proximity to the gold surface, and most of the fluorescence is quenched. After hybridization with a target the hairpin opens, the fluorophore and surface become separated, and the fluorescence drastically increases. Using this detection method the sensitivity is limited by the difference in the fluorescence intensity in the closed and open state. As the background fluorescence is mainly caused by non-quenched fluorophores, a strategy to reduce the background fluorescence is to cut the beacon in two halves. First a thiolated ssDNA capture probe strand (first half) is chemisorbed to a gold surface together with relatively short thiol spacers. Next the target is hybridized by one end to the surface-anchored capture probe and by the other to a fluorophore-labeled reporter probe DNA (second half). The signal readout is done by surface plasmon fluorescence spectroscopy (SPFS). Using this detection strategy the background fluorescence can be significantly lowered, and the detection limit is lowered by more than one order of magnitude. The detection of a target takes only a few minutes and the sensor chips can be used for multiple detection steps without a significant decrease in performance.

A large drop in hybridization signal of single base mismatched alleles using the designed probe as compared with the conventional probe, from 80% to less than 25% of the signal obtained with the fully complementary, non-mutation-containing sequence, when using colorimetric detection was further improved to 20% when using electrochemical detection, attributable to a difference of spacing of immobilized probes. Finally, the designed probe was used for the electrochemical detection of the DQA1*05:05 allele amplified from real human blood samples.

Abstract
High selectivity of genosensors is crucial for certain applications such as those involving species with high genetic variability. This is an unresolved problem when dealing with long target sequences that is further complicated when the target contains repetitive sequence domains. As a model for this situation, the problem of detecting gluten in food with identification of the source is studied. In order to discriminate the specific DNA sequence that encodes the wheat prolamin (gliadin) from rye and barley prolamins, the exquisite selectivity of a rationally designed hairpin capture probe is proposed and compared to a nonstructured capture probe. An electrochemical sandwich assay is proposed, involving capture probes chemisorbed on Au surfaces and biotinylated-signaling probes in combination with streptavidin-peroxidase labeling conjugates. As a result, a genosensor with similar sensitivity to that observed with linear probes but with complete specificity against closely related species was achieved. The surface-attached DNA stem-loop yields a device capable of accurately discriminating wheat DNA from rye and barley with a limit of detection of 1 nM.

Abstract
In this paper, horseradish peroxidase-mimicking DNAzyme (HRP-DNAzyme) and Prussian blue (PB)-gold (Au) nanocomposites were designed as versatile electrochemical sensing platforms for the amplified detection of DNA, Hg(2+) and adenosine triphosphate (ATP). By the conjugation of the target probe with the capture probe, a conformational change resulted in the formation of HRP-DNAzyme on the PB-Au modified electrode. The redox of HRP-DNAzyme (red) was efficiently carried out in the presence of H2O2, in which PB acted as a mediator stimulating the biocatalytic functions of HRP-DNAzyme and actuated a catalytic cycle bringing an amplified signal. Specific recognition of the target DNA, Hg(2+) and ATP allowed selective amperometric detection of the target molecule. The detection limits of DNA, Hg(2+) and ATP were 50 nM, 30 pM and 3 nM, respectively. The highlight of this work is that the catalytic cycle between PB-Au nanocomposites and HRP-DNAzyme was adequately utilized in the amplification platform for versatile sensing. The novel electrocatalytic biosensor involving only one-step incubation exhibited a wide linear range, low detection limit, and satisfactory selectivity and operational stability. The proposed approach provided an ease-of-use and universal reporting system with a simple design and easy operations.

Abstract
The amplified, highly sensitive detection of DNA using the dendritic rolling circle amplification (RCA) is introduced. The analytical platform includes a circular DNA and a structurally tailored hairpin structure. The circular nucleic acid template includes a recognition sequence for the analyte DNA (the Tay-Sachs mutant gene), a complementary sequence to the Mg(2+)-dependent DNAzyme, and a sequence identical to the loop region of the coadded hairpin structure. The functional hairpin in the system consists of the analyte-sequence that is caged in the stem region and a single-stranded loop domain that communicates with the RCA product. The analyte activates the RCA process, leading to DNA chains consisting of the Mg(2+)-dependent DNAzyme and sequences that are complementary to the loop of the functional hairpin structure. Opening of the coadded hairpin releases the caged analyte sequence, resulting in the dendritic RCA-induced synthesis of the Mg(2+)-dependent DNAzyme units. The DNAzyme-catalyzed cleavage of a fluorophore/quencher-modified substrate leads to a fluorescence readout signal. The method enabled the analysis of the target DNA with a detection limit corresponding to 1 aM. By the design of two different circular DNAs that include recognition sites for two different target genes, complementary sequences for two different Mg(2+)-dependent DNAzyme sequences and two different functional hairpin structures, the dendritic RCA-stimulated multiplexed analysis of two different genes is demonstrated. The amplified dendritic RCA detection of DNA is further implemented to yield the hemin/G-quadruplex horseradish peroxidase (HRP)-mimicking DNAzyme as catalytic labels that provide colorimetric or chemiluminescent readout signals.

Abstract
A synthetic redox probe structurally related to natural pyridoacridones was designed and electrochemically characterised. These heterocycles behave as DNA intercalators due to their extended planar structure that promotes stacking in between nucleic acid base pairs. Electrochemical characterization by cyclic voltammetry revealed a quasi-reversible electrochemical behaviour occurring at a mild negative potential in aqueous solution. The study of the mechanism showed that the iminoquinone redox moiety acts similarly to quinone involving a two-electron reduction coupled with proton transfer. The easily accessible potential region with respect to aqueous electro-inactive window makes the pyridoacridone ring suitable for the indirect electrochemical detection of chemically unlabelled DNA. Its usefulness as electrochemical hybridization indicator was assessed on immobilised DNA and compared to doxorubicin. The voltamperometric response of the intercalator acts as an indicator of the presence of double-stranded DNA at the electrode surface and allows the selective transduction of immobilised oligonucleotide hybridization at both macro- and microscale electrodes.

Abstract
The progressive development of amplified DNA sensors and aptasensors using replication/nicking enzymes/DNAzyme machineries is described. The sensing platforms are based on the tailoring of a DNA template on which the recognition of the target DNA or the formation of the aptamer-substrate complex trigger on the autonomous isothermal replication/nicking processes and the displacement of a Mg(2+)-dependent DNAzyme that catalyzes the generation of a fluorophore-labeled nucleic acid acting as readout signal for the analyses. Three different DNA sensing configurations are described, where in the ultimate configuration the target sequence is incorporated into a nucleic acid blocker structure associated with the sensing template. The target-triggered isothermal autonomous replication/nicking process on the modified template results in the formation of the Mg(2+)-dependent DNAzyme tethered to a free strand consisting of the target sequence. This activates additional template units for the nucleic acid self-replication process, resulting in the ultrasensitive detection of the target DNA (detection limit 1 aM). Similarly, amplified aptamer-based sensing platforms for cocaine are developed along these concepts. The modification of the cocaine-detection template by the addition of a nucleic acid sequence that enables the autonomous secondary coupled activation of a polymerization/nicking machinery and DNAzyme generation path leads to an improved analysis of cocaine (detection limit 10 nM).

Abstract
Genetic analysis of infectious and genetic diseases and cancer diagnostics require the development of efficient tools for fast and reliable analysis of single-nucleotide polymorphism (SNP) in targeted DNA and RNA sequences often responsible for signalling disease onset. Here, we highlight the main trends in the development of electrochemical genosensors for sensitive and selective detection of SNP that are based on hairpin DNA architectures exhibiting better SNP recognition properties compared with linear DNA probes. SNP detection by electrochemical hairpin DNA beacons is discussed, and comparative analysis of the existing SNP sensing strategies based on enzymatic and nanoparticle signal amplification schemes is presented.

Abstract
Attomole (10(-18)mol) levels of RNA and DNA isolated from beer spoilage bacterial cells Lactobacillus brevis have been detected by the electrochemical sandwich DNA hybridization assay exploiting enzymatic activity of lipase. DNA sequences specific exclusively to L. brevis DNA and RNA were selected and used for probe and target DNA design. The assay employs magnetic beads (MB) modified with a capture DNA sequence and a reporter DNA probe labeled with the enzyme, both made to be highly specific for L. brevis DNA. Lipase-labeled DNAs captured on MBs in the sandwich assay were collected on gold electrodes modified with a ferrocene (Fc)-terminated SAM formed by aliphatic esters. Lipase hydrolysis of the ester bond released a fraction of the Fc redox active groups from the electrode surface, decreasing the electrochemical signal from the surface-confined Fc. The assay, shown to be efficient for analysis of short synthetic DNA sequences, was ineffective with genomic double stranded bacterial DNA, but it allowed down to 16 amole detection of 1563 nts long RNA, isolated from bacterial ribosomes without the need for PCR amplification, and single DNA strands produced from ribosomal RNA. No interference from E. coli RNA was registered. The assay allowed analysis of 400 L. brevis cells isolated from 1L of beer, which fits the "alarm signal" range (from 1 to 100 cells per 100mL).

Abstract
The Zn(2+)-dependent ligation DNAzyme is implemented as a biocatalyst for the amplified detection of a target DNA by the autonomous replication of a nucleic acid reporter unit that is generated by the catalyzed ligation process. The reporter units enhance the formation of active DNAzyme units, thus leading to the isothermal autocatalytic formation of the reporter elements. The system was further developed and applied for the amplified detection of Tay-Sachs genetic disorder mutant, with a detection limit of 1.0 × 10(-11) M. Besides providing a versatile paradigm for the amplified detection of DNA, the system reveals a new, enzyme-free, isothermal, autocatalytic mechanism that introduces means for effective programmed synthesis.
