Abstract
Accessibility of synthetic oligonucleotides and the success of DNA nanotechnology open a possibility to use DNA nanostructures for building sophisticated enzyme-like catalytic centers. Here we used a double DNA crossover (DX) tile nanostructure to enhance the rate, the yield, and the specificity of 5'-5' ligation of two oligonucleotides with arbitrary sequences. The ligation product was isolated via a simple procedure. The same strategy was applied for the synthesis of 3'-3' linked oligonucleotides, thus introducing a synthetic route to DNA and RNA with a switched orientation that is affordable by a low-resource laboratory. To emphasize the utility of the ligation products, we synthesized a circular structure formed from intramolecular complementarity that we named "an impossible DNA wheel" since it cannot be built from regular DNA strands by enzymatic reactions. Therefore, DX-tile nanostructures can open a route to producing useful chemical products that are unattainable via enzymatic synthesis. This is the first example of the use of DNA nanostructures as a catalyst. This study advocates for further exploration of DNA nanotechnology for building enzyme-like reactive systems.

Abstract
Nucleic-acid-templated chemical reactions are currently explored for applications in DNA-encoded drug discovery, nucleic acid diagnostics, and theranostics. Of particular interest are reactions enabling the template to gain catalytic activity, so that enzymatic amplification of low copy targets would no longer be necessary. Herein, we introduce a new reaction design relying on the template-controlled cleavage of PNA-spermine conjugates. With turnover frequencies in the range of 3-10 min-1 and a kcat/KM = 1.3 × 106 M-1 s-1, the loss of affinity upon reaction provides a catalytic efficiency equal to most enzymatic conversions and superior to nucleic-acid-templated reactions reported to date.

Abstract
Fluorogenic hybridization probes allow the detection of RNA and DNA sequences in homogeneous solution. Typically, one target molecule activates the fluorescence of a single probe molecule. This limits the sensitivity of nucleic acid detection. Herein, we report a self‐immolative molecular beacon (iMB) that escapes the one‐target/one‐probe paradigm. The iMB probe includes a photoreductively cleavable N‐alkyl‐picolinium (NAP) linkage within the loop region. A fluorophore at the 5’‐end serves, on the one hand, as a reporter group and, on the other hand, as a photosensitizer of a NAP‐linker cleavage reaction. In the absence of target, the iMB adopts a hairpin shape. Quencher groups prevent photo‐induced cleavage. The iMB opens upon hybridization with a target, and both fluorescent emission as well as photo‐reductive cleavage of the NAP linker can occur. In contrast to previous chemical amplification reactions, iMBs are unimolecular probes that undergo cleavage leading to products that have lower target affinity than the probes before reaction. Aided by catalysis, the method allowed the detection of 5 pm RNA target within 100 min.

Abstract
Sequence-specific detection of intracellular RNA is one of the most important approaches to understand life phenomena. However, it is difficult to detect RNA in living cells because of its variety and scarcity. In the last three decades, several chemical probes have been developed for RNA detection in living cells. These probes are composed of DNA or artificial nucleic acid and hybridize with the target RNA in a sequence-specific manner. This hybridization triggers a change of fluorescence or a chemical reaction. In this review, we classify the probes according to the associated fluorogenic mechanism, that is, interaction between fluorophore and quencher, environmental change of fluorophore, and template reaction with/without ligation. In addition, we introduce examples of RNA imaging in living cells.

Abstract
By combining azobenzene-tethered oligonucleotides as modulators and poly(l-lysine)-graft-dextran (PLL-g-Dex), a chaperone polymer, to facilitate strand displacement, we successfully developed a photo-regulatable DNA isothermal amplification method. By alternating UV and visible irradiation, linear amplification was achieved. The method enables photo-regulatability and mismatch discrimination in linear amplification of the DNA target.

Abstract
A 3'-N,5'-S-bridging thiophosphoramidate analogue of thymidylyl-3',5'-thymidine was synthesised under aqueous conditions. (1)H NMR conformational measurements show that the 3'-N-substituted deoxyribose ring is biased towards the 'north', RNA-like conformation. Rate constants for hydrolysis of the analogue were measured at 90 °C in the pH range 1.3-10.9. The pH-log kobs profile displays a pH-independent region between approximately pH 7 and 10 (t1/2 ∼13 days). Under acidic conditions, kobs displays a first order dependence on [H3O(+)].

Abstract
Nucleic acid templated reactions have attracted attention as an important technology to sense oligonucleotides and to translate nucleic acid-based instructions into diverse outputs. Great progress has been made in accelerating the reaction in order to improve signal amplification, reaching rates where substrate turnover rather than chemical reaction is rate limiting. Herein we explore the utility of architectures inspired by three-way junction that yield a cleavage of a strand thus accelerating substrate turnover. We demonstrate that such design can overcome product inhibition in templated reactions and operate close to the rate of hybridization.

Abstract
Protein-templated reactions have been used for fragment-based drug discovery as well as for covalent labeling, detection and manipulation of proteins. In spite of the growing interest in protein-templated reactions, little is known about the design criteria. Herein we present a systematic study on the effects of proximity in peptide-templated reactions. To facilitate reaction monitoring at low concentrations we developed a fluorogenic native chemical ligation that is based on the integration of a fluorescence quencher in the thiol leaving group. The reaction system provided up to 39-fold increases of emission from a fluorescein unit. By using templates based on coiled coils as models we investigated the effect of misalignments. The distance-reactivity pattern for remotely aligned peptides was remarkably different to reaction scenarios that involved seamlessly annealed peptides with overhanging functional groups.

Abstract
Nucleic acids detection is essential to the study of biological processes and to diagnosis of pathological states. Although PCR is highly effective in vitro, methods that can function without prior sample preparation, thermal cycling, or enzymes are of interest due to their simplicity. Most current non-PCR detection methods rely on linear signal amplification, which hinders the detection of small amounts of genetic material. To address this limitation, we tested a new strategy for attaining higher-order signal amplification, in which a target sequence templates a chemical ligation, and the product of this reaction is in turn detected with a second templated reaction. The method is nonenzymatic, isothermal, and fluorogenic, allowing the direct detection of nucleic acids in complex matrices. Using this approach, as little as 500 attomoles (10 pM) could be detected with single nucleotide resolution. In a test of selectivity, single nucleotide substitutions and deletions could successfully be detected, including a deletion that is associated with tetracycline resistance in Helicobacter pylori. Compatibility with biological matrices was demonstrated by the direct detection of rRNA in bacterial lysate. Imaging and detection of target sequences on a solid support further illustrates the potential of the new approach for high-throughput analysis.

Abstract
We have developed a novel type of biofunction-assisted, signal-turn-on sensor for simply and homogenously detecting DNA. This sensor system is composed of two types of in vitro-transcribed label-free RNAs (a 3' premature amber suppressor tRNA probe and an amber-mutated mRNA encoding a reporter protein), RNase H, and a wheat germ extract (WGE). A target DNA induces the 3' end maturation of the tRNA probe, which is enhanced by RNase H and leads to the expression of a full-length reporter protein through amber suppression in WGE, while there is almost no expression without the target due to the inactivity of the premature probe. Therefore, the target can be readily detected with the activity of the translated reporter. The catalytic reuse of the target with the help of RNase H in addition to various bioprocesses in WGE enables this sensor system to exhibit relatively high selectivity and sensitivity.

Abstract
An alternative to qPCR was developed for nucleic acid assays, involving signal rather than target amplification. The new technology, Restriction Cascade Exponential Amplification (RCEA), relies on specific cleavage of probe-target hybrids by restriction endonucleases (REase). Two mutant REases for amplification (Ramp), S17C BamHI and K249C EcoRI, were conjugated to oligonucleotides, and immobilized on a solid surface. The signal generation was based on: (i) hybridization of a target DNA to a Ramp-oligonucleotide probe conjugate, followed by (ii) specific cleavage of the probe-target hybrid using a non-immobilized recognition REase. The amount of Ramp released into solution upon cleavage was proportionate to the DNA target amount. Signal amplification was achieved through catalysis, by the free Ramp, of a restriction cascade containing additional oligonucleotide-conjugated Ramp and horseradish peroxidase (HRP). Colorimetric quantification of free HRP indicated that the RCEA achieved a detection limit of 10 aM (10−17 M) target concentration, or approximately 200 molecules, comparable to the sensitivity of qPCR-based assays. The RCEA assay had high specificity, it was insensitive to non-specific binding, and detected target sequences in the presence of foreign DNA. RCEA is an inexpensive isothermal assay that allows coupling of the restriction cascade signal amplification with any DNA target of interest.

Abstract
There is an immediate need for rapid triage of the population in case of a large scale exposure to ionizing radiation. Knowing the dose absorbed by the body will allow clinicians to administer medical treatment for the best chance of recovery for the victim. In addition, today's radiotherapy treatment could benefit from additional information regarding the patient's sensitivity to radiation before starting the treatment. As of today, there is no system in place to respond to this demand. This paper will describe specific procedures to mimic the effects of human exposure to ionizing radiation creating the tools for optimization of administered radiation dosimetry for radiotherapy and/or to estimate the doses of radiation received accidentally during a radiation event that could pose a danger to the public. In order to obtain irradiated biological samples to study ionizing radiation absorbed by the body, we performed ex-vivo irradiation of human blood samples using the linear accelerator (LINAC). The LINAC was implemented and calibrated for irradiating human whole blood samples. To test the calibration, a 2 Gy test run was successfully performed on a tube filled with water with an accuracy of 3% in dose distribution. To validate our technique the blood samples were ex-vivo irradiated and the results were analyzed using a gene expression assay to follow the effect of the ionizing irradiation by characterizing dose responsive biomarkers from radiobiological assays. The response of 5 genes was monitored resulting in expression increase with the dose of radiation received. The blood samples treated with the LINAC can provide effective irradiated blood samples suitable for molecular profiling to validate radiobiological measurements via the gene-expression based biodosimetry tools.

Abstract
Efforts to chemically ligate oligonucleotides, without resorting to biochemical enzymes, have led to a multitude of synthetic analogues, and have extended oligomer ligation to reactions of novel oligonucleotides, peptides, and hybrids such as PNA.1 Key requirements for potential diagnostic tools not based on PCR include a fast templated chemical DNA ligation method that exhibits high pairing selectivity, and a sensitive detection method. Here we report on a solid-phase synthesis of oligonucleotides containing 5'- or 3'-mercapto-dideoxynucleotides and their chemical ligations, yielding 3'-5'-disulfide bonds as a replacement for 3'-5'-phosphodiester units. Employing a system designed for fluorescence monitoring, we demonstrate one of the fastest ligation reactions with half-lives on the order of seconds. The nontemplated ligation reaction is efficiently suppressed by the choice of DNA modification and the 3'-5' orientation of the activation site. The influence of temperature on the templated reaction is shown.

Abstract
This review analyses the literature concerning non-fluorescent and fluorescent probes for nucleic acid imaging in fixed and living cells from the point of view of their suitability for imaging intracellular native RNA and DNA. Attention is mainly paid to fluorescent probes for fluorescence microscopy imaging. Requirements for the target-binding part and the fluorophore making up the probe are formulated. In the case of native double-stranded DNA, structure-specific and sequence-specific probes are discussed. Among the latest, three classes of dsDNA-targeting molecules are described: (i) sequence-specific peptides and proteins; (ii) triplex-forming oligonucleotides and (iii) polyamide oligo(N-methylpyrrole/N-methylimidazole) minor groove binders. Polyamides seem to be the most promising targeting agents for fluorescent probe design, however, some technical problems remain to be solved, such as the relatively low sequence specificity and the high background fluorescence inside the cells. Several examples of fluorescent probe applications for DNA imaging in fixed and living cells are cited. In the case of intracellular RNA, only modified oligonucleotides can provide such sequence-specific imaging. Several approaches for designing fluorescent probes are considered: linear fluorescent probes based on modified oligonucleotide analogs, molecular beacons, binary fluorescent probes and template-directed reactions with fluorescence probe formation, FRET donor-acceptor pairs, pyrene excimers, aptamers and others. The suitability of all these methods for living cell applications is discussed.

Abstract
Programmable interactions allow nucleic acid molecules to template chemical reactions by increasing the effective molarities of appended reactive groups. DNA/RNA-triggered reactions can proceed, in principle, with turnover in the template. The amplification provided by the formation of many product molecules per template is a valuable asset when the availability of the DNA or RNA target is limited. However, turnover is usually impeded by reaction products that block access to the template. Product inhibition is most severe in ligation reactions, where products after ligation have dramatically increased template affinities. We introduce a potentially generic approach to reduce product inhibition in nucleic acid-programmed ligation reactions. A DNA-triggered ligation-cyclization sequence ("cycligation") of bifunctional peptide nucleic acid (PNA) conjugates affords cyclic ligation products. Melting experiments revealed that product cyclization is accompanied by a pronounced decrease in template affinity compared to linear ligation products. The reaction system relies upon haloacetylated PNA-thioesters and isocysteinyl-PNA-cysteine conjugates, which were ligated on a DNA template according to a native chemical ligation mechanism. Dissociation of the resulting linear product-template duplex (induced by, for example, thermal cycling) enabled product cyclization through sulfur-halide substitution. Both ligation and cyclization are fast reactions (ligation: 86 % yield after 20 min, cyclization: quantitative after 5 min). Under thermocycling conditions, the DNA template was able to trigger the formation of new product molecules when fresh reactants were added. Furthermore, cycligation produced 2-3 times more product than a conventional ligation reaction with substoichiometric template loads (0.25-0.01 equiv). We believe that cyclization of products from DNA-templated reactions could ultimately afford systems that completely overcome product inhibition.

Abstract
Advances in the fields of proteomics, molecular imaging, and therapeutics are closely linked to the availability of affinity reagents that selectively recognize their biological targets. Here we present a review of Iterative Peptide In Situ Click Chemistry (IPISC), a novel screening technology for designing peptide multiligands with high affinity and specificity. This technology builds upon in situ click chemistry, a kinetic target-guided synthesis approach where the protein target catalyzes the conjugation of two small molecules, typically through the azide-alkyne Huisgen cycloaddition. Integrating this methodology with solid phase peptide libraries enables the assembly of linear and branched peptide multiligands we refer to as Protein Catalyzed Capture Agents (PCC Agents). The resulting structures can be thought of as analogous to the antigen recognition site of antibodies and serve as antibody replacements in biochemical and cell-based applications. In this review, we discuss the recent progress in ligand design through IPISC and related approaches, focusing on the improvements in affinity and specificity as multiligands are assembled by target-catalyzed peptide conjugation. We compare the IPISC process to small molecule in situ click chemistry with particular emphasis on the advantages and technical challenges of constructing antibody-like PCC Agents.

Abstract
Widespread in nature, oligonucleotide-templated reactions of phosphodiester bond formation have inspired chemists who are now applying this elegant strategy to the catalysis of a broad range of otherwise inefficient reactions. This review highlights the increasing diversity of chemical reactions that can be efficiently catalysed by an oligonucleotide template, using Watson-Crick base-pairing to bring both reagents in close enough proximity to react, thus increasing significantly their effective molarity. The applications of this elegant concept for nucleic acid sensing and controlled organic synthesis will also be discussed.

Abstract
We have developed an assay for single strand DNA or RNA detection which is based on the homo-DNA templated Staudinger reduction of the profluorophore rhodamine-azide. The assay is based on a three component system, consisting of a homo-DNA/DNA hybrid probe, a set of homo-DNA reporter strands and the target DNA or RNA. We present two different formats of the assay (Omega probe and linear probe) in which the linear probe was found to perform best with catalytic turnover of the reporter strands (TON: 8) and a match/mismatch discrimination of up to 19. The advantage of this system is that the reporting (homo-DNA) and sensing (DNA) domain are decoupled from each other since the two pairing systems are bioorthogonal. This allows independent optimization of either domain which may lead to higher selectivity in in vivo imaging.

Abstract
A highly sensitive DNA biosensing method down to sub-femtomolar level with excellent selectivity was proposed by designing an amplified synthesis of horseradish peroxidase mimicking DNAzyme and introducing the amplified DNAzyme to chemiluminescent (CL) imaging. The amplified synthesis was achieved by combining a target DNA related ligase reaction with rolling circle amplification (RCA), which produced thousands of repeated sequences to bind hemin and form a mass of horseradish peroxidase-mimicing DNAzyme units. The amplification strategy greatly enhanced the CL emission of the luminol-H(2)O(2) system. The genotyping method displayed highly specific biochemistry in allele discrimination. The novel CL imaging strategy based on ligation-mediated RCA synthesis of DNAzyme showed high fidelity in discriminating single-base mismatch and efficiently facilitated signal amplification for sensitive target DNA detection. It could detect DNA ranging from 1×10(-15) M to 1×10(-11) M with a detection limit of 0.26 fM. The proposed approach provided a robust, cost-efficient, highly sensitive and specific platform for genetic target analysis in bioanalysis and clinic biomedical application.

Abstract
A methylene-blue (MB)-labeled molecular beacon junction probe allows for a signal-on electrochemical detection of nucleic acids via target recycling using endonucleases. Electron transfer is reduced when the MB is intercalated in the stem of the molecular beacon, but then electron transfer from MB to a gold electrode is enhanced upon cleavage of the junction probe due to increased probability of MB approaching the electrode when attached to the more flexible ssDNA.

Abstract
Double-stranded DNA (dsDNA) templates can hybridize to and accelerate cleavage of oligonucleotides containing a P3'→N5' phosphoramidate (P-N) linkage. This dsDNA-templated cleavage of P-N linkages could be due to conformational strain placed on the linkage upon triplex formation. To determine whether duplex formation also induced conformational strain, we examined the reactivity of the oligonucleotides with a P-N linkage in the presence of single-stranded templates, and compared these reactions to those with dsDNA templates. P-N oligonucleotides that are cleaved upon duplex formation could be used as probes to detect single-stranded nucleic acids.

Abstract
Here we describe the first use of small-molecule binding to direct a chemical reaction between two nucleic acid strands. The reported reaction is a ligation between two fragments of a DNA split aptamer using strain-promoted azide-alkyne cycloaddition. Utilizing the split aptamer for cocaine, we demonstrate small-molecule-dependent ligation that is dose-dependent over a wide range of cocaine concentrations and is compatible with complex biological fluids such as human blood serum. Moreover, studies of split aptamer ligation at varying salt concentrations and using structurally similar analogues of cocaine have revealed new insight into the assembly and small-molecule binding properties of the cocaine split aptamer. The ability to translate the presence of a small-molecule target into the output of DNA ligation is anticipated to enable the development of new, broadly applicable small-molecule detection assays.

Abstract
Quenched autoligation probes have been employed previously in a target-templated nonenzymatic ligation strategy for detecting nucleic acids in cells by fluorescence. A common source of background signal in such probes is the undesired reaction with water and other cellular nucleophiles. Here, we describe a new class of self-ligating probes, double displacement (DD) probes, that rely on two displacement reactions to fully unquench a nearby fluorophore. Three potential double displacement architectures, all possessing two fluorescence quencher/leaving groups (dabsylate groups), were synthesized and evaluated for templated reaction with nucleophile (phosphorothioate) probes both in vitro and in intact bacterial cells. All three DD probe designs provided substantially better initial quenching than a single-Dabsyl control. In isothermal templated reactions in vitro, double displacement probes yielded considerably lower background signal than previous single displacement probes; investigation into the mechanism revealed that one dabsylate acts as a sacrificial leaving group, reacting nonspecifically with water, but yielding little signal because another quencher group remains. Templated reaction with the specific nucleophile probe is required to activate a signal. The double displacement probes provided a ca. 80-fold turn-on signal and yielded a 2-4-fold improvement in signal/background over single Dabsyl probes. The best-performing probe architecture was demonstrated in a two-color, FRET-based two-allele discrimination system in vitro and was shown to be capable of discriminating between two closely related species of bacteria differing by a single nucleotide at an rRNA target site.

Abstract
Fluorescence-quenched nucleic acid probes with reactive moieties at both the 5' and 3' ends are synthesized and tested for reaction with two adjacent nucleophile-containing DNAs. These probes improve signal to background over singly reactive probes and can discriminate single nucleotide polymorphisms in the target DNA or RNA.

Abstract
We recently reported double-stranded DNA-templated cleavage of oligonucleotides as a sequence-specific DNA-detecting method. In this method, triplex-forming oligonucleotides (TFOs) modified with 5′-amino-2′,4′-BNA were used as a DNA-detecting probe. This modification introduced a P3′→N5′ linkage (P–N linkage) in the backbone of the TFO, which was quickly cleaved under acidic conditions when it formed a triplex. The prompt fission of the P–N linkage was assumed to be driven by a conformational strain placed on the linkage upon triplex formation. Therefore, chemical modifications around the P–N linkage should change the reactivity by altering the microenvironment. We synthesized 5′-aminomethyl type nucleic acids, and incorporated them into TFOs instead of 5′-amino-2′,4′-BNA to investigate the effect of 5′-elongation. In addition, 2′,4′-BNA/LNA or 2′,5′-linked DNA were introduced at the 3′- and/or 5′-neighboring residues of 5′-amino-2′,4′-BNA to reveal neighboring residual effects. We evaluated the triplex stability and reaction properties of these TFOs, and found out that chemical modifications around the P–N linkage greatly affected their reaction properties. Notably, 2′,5′-linked DNA at the 3′ position flanking 5′-amino-2′,4′-BNA brought significantly higher reactivity, and we succeeded in indicating that a TFO with this modification is promising as a DNA analysis tool.

Abstract
RNA-templated fluorescence activation is a nucleic acid detection strategy that offers the possibility of direct visual detection of genetic information in living cells. Here we describe a new reaction strategy for fluorescence activation in which a phosphine on one DNA probe reduces an azide group in a linker on a second probe, resulting in linker cleavage and release of a fluorescence quenching group. These "Q-STAR" probes are shown to yield a strong fluorescence turn-on signal in approximately 20 min, with very low background and substantial amplification by turnover on the template. A green/red pair of such probes allowed the discrimination of two bacterial species by a single nucleotide difference in their 16S rRNA. The beneficial properties of the reductive quencher release design make these probes promising candidates for widespread application in the detection of nucleic acids in vitro and in cells.

Abstract
Split G-rich DNA probes can assemble into active peroxidase-mimicking DNAzymes in the presence of bioanalytes such as DNA, thereby providing a simple and cheap means to detect analytes in biological samples. A comprehensive study designed to reveal the salient probe architectural features and reaction conditions that facilitate facile reconstitution into enzymatically proficient enzymes unveiled these important findings: (a) The loops that connect the G3-tracts in a G-quadruplex structure can be replaced with a stem-loop or loop-stem-loop motif without destabilizing the resulting quadruplex structure; endowing the split G-rich probes with regions of limited complementarity leads to more proficient reconstituted enzymes. (b) The addition of hemin to antiparallel G-quadruplex DNAzymes lead to a blue shift in the CD spectra of the G-quadruplex DNAzymes. (c) The architectures of the DNA motifs that lie adjacent to the G-quadruplex structure influence both the stability and the enzymatic proficiency of the reconstituted enzymes. (d) The nature of the monovalent cation that is present in excess is a key determinant of the turnover number of the G-quadruplex DNAzyme; decomposition of G-quadruplex DNAzymes is slower in buffers that contain ammonium ions than those that contain sodium or potassium ions. These findings are important for the design of bioassays that use peroxidase-mimicking G-quadruplexes as detection labels.

Abstract
DNA- and RNA-templated chemical reactions can serve as a diagnostic means for the detection of nucleic acids. Reaction schemes that allow amplified detection are of high interest for polymerase chain reaction (PCR)-free DNA and RNA diagnosis. These reactions typically draw upon the catalytic activity of the template, which is able to trigger the conversion of many signaling molecules per template molecule. However, the design of reactive probes that allow both sensitive and selective nucleic acid detection is a challenge and requires insight into three major parameters: a) reactivity of functional groups involved, b) affinity of probes for the template, and c) the readout system. In this study we used peptide nucleic acid (PNA)-based probes to investigate in detail the signaling power and the selectivity of a transfer reaction derived from a native chemical ligation. We show that subtle variations of the thioesters involved had a tremendous impact on the sensitivity and selectivity of the reaction system. The results suggest that reactions at turnover conditions require low rates of non-templated reaction pathways to provide high target selectivity and sensitivity. On the other hand, very high rates of templated reactions should be avoided to allow mismatched probe-template complexes to dissociate prior to bond formation. Furthermore, the temperature dependence of the DNA-catalyzed transfer reaction was studied and provided insight into crucial strand-exchange processes. Further improvements of selective signaling were achieved through a new readout based on pyrene-transfer reactions. This method reduces background signals and enables significant increases in the signaling rates compared with previous fluorescence-based methods.
