Abstract
DNA-templated reactions have found wide applications in sensing and drug discovery. However, this strategy has been limited to the use of nucleic acids as templating elements to direct the proximity effect. Herein, we describe a versatile protein-templated split aptamer click ligation reaction (PT-SpA-CLR) in which the protein template-induced covalent proximity ligation of split aptamer elements enables translating protein/aptamer binding events into the output of ligated DNA products. A ligation yield of >80% is observed for three model protein templates, including VEGF165, PDGF-BB, and SARS-CoV-2 S1. The ligation reaction compensates for the weakness of reduced binding affinity resulting from splitting the aptamer, as evidenced by an approximately 2-fold lower dissociation constant than the non-ligated system. This newly developed PT-SpA-CLR strategy is further integrated with colorimetric or fluorescent reporting mechanisms to achieve easy-to-use and low-cost biosensors utilizing ligation to produce a fully active G-quadruplex or an RNA-cleaving DNAzyme to report protein binding. Both assays can achieve specific detection of an intended protein target with a limit of detection at the picomolar level even when challenged in biological samples. The combined PT-SpA-CLR and versatile sensing strategies offer attractive universal platforms for efficient detection of protein biomarkers.

Abstract
A novel method for synthesizing cationic styryl dyes through a nucleic acid-templated reaction has been developed. This approach overcomes issues associated with traditional synthesis methods, such as harsh conditions, low throughput, and wasteful chemicals. The presence of a nucleic acid template accelerated the styryl dye formation from quaternized heteroaromatic and cationic aldehyde substrates. These styryl dyes show remarkable optical properties change when bound to nucleic acids, hence the success of the synthesis could be readily monitored in situ by UV-Vis and fluorescence spectroscopy and the optical properties data were also observable at the same time. This method provides the desired products from a broad range of coupling partners. By employing different substrates and templates, it is possible to identify new dyes that can bind to a specific type of nucleic acid such as a G-quadruplex. The templated dye synthesis is also successfully demonstrated in live HeLa cells. This approach is a powerful tool for the rapid synthesis and screening of dyes specific for diverse types of nucleic acids or cellular organelles, facilitating new biological discoveries.

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
Reactions templated by nucleic acids are currently at the heart of applications in biosensing and drug release. The number of chemical reactions selectively occurring only in the presence of the template, in aqueous solutions, and at room temperature and able to release a chemical moiety is still very limited. Here, we report the use of the p-nitrophenyl carbonate (NPC) as a new reactive moiety for DNA templated reactions releasing a colored reporter by reaction with a simple amine. The easily synthesized p-nitrophenyl carbonate was integrated in an oligonucleotide and showed a very good stability as well as a high reactivity toward amines, without the need for any supplementary reagent, quantitatively releasing the red p-nitrophenolate with a half-life of about 1 h.

Abstract
In light of the 2018 Max Bergmann Medal, this review discusses advancements on chemical biology-driven templated chemistry developed in the author's laboratories. The focused review introduces the template categories applied to orient functional units such as functional groups, chromophores, biomolecules, or ligands in space. Unimolecular templates applied in protein synthesis facilitate fragment coupling of unprotected peptides. Templating via bimolecular assemblies provides control over proximity relationships between functional units of two molecules. As an instructive example, the coiled coil peptide-templated labelling of receptor proteins on live cells will be shown. Termolecular assemblies provide the opportunity to put the proximity of functional units on two (bio)molecules under the control of a third party molecule. This allows the design of conditional bimolecular reactions. A notable example is DNA/RNA-triggered peptide synthesis. The last section shows how termolecular and multimolecular assemblies can be used to better characterize and understand multivalent protein-ligand interactions.

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
Photoclickable fluorogenic probes will enable visualization of specific biomolecules with precise spatiotemporal control in their native environment. However, the fluorogenic tagging of DNA with current photocontrolled clickable probes is still challenging. Herein, we demonstrated the fast (19.5 ± 2.5 M-1 s-1) fluorogenic labeling and imaging of DNA in vitro and in vivo with rationally designed coumarin-fused tetrazoles under UV LED photoirradiation. With a water-soluble, nuclear-specific coumarin-fused tetrazole (CTz-SO3), the metabolically synthesized DNA in cultured cells was effectively labeled and visualized, without fixation, via "photoclick" reaction. Moreover, the photoclickable CTz-SO3 enabled real-time, spatially controlled imaging of DNA in live zebrafish.

Abstract
Here, the synthesis of a RuII photocatalyst by light-directed oligonucleotide-templated ligation reaction is described. The photocatalyst was found to have tremendous potential for signal amplification with >15000 turnovers measured in 9 hours. A templated reaction was used to turn on the activity of this ruthenium(II) photocatalyst in response to a specific DNA sequence. The photocatalysis of the ruthenium(II) complex was harnessed to uncage a new precipitating dye that is highly fluorescent and photostable in the solid state. This reaction was used to discriminate between different DNA analytes based on localization of the precipitate as well as for in cellulo miRNA detection. Finally, a bipyridine ligand functionalized with two different peptide nucleic acid (PNA) sequences was shown to enable template-mediated ligation (turn on of the ruthenium(II) photocatalysis) and recruitment of substrate for templated photocatalysis.

Abstract
With this Feature Article we review, for the first time, the development of DNA-host conjugates-a nascent yet rapidly growing research focus within the ambit of DNA supramolecular chemistry. Synthetic hosts (such as cyclodextrins, cucurbiturils, and calixarenes) are well-suited to be partnered with DNA, since DNA assembly and host-guest binding both thrive in aqueous media, are largely orthogonal, and exhibit controllable and input-responsive properties. The covalent braiding of these two supramolecular synthons thus leads to advanced self-assemblies and nanostructures with exciting function that range from drug delivery agents to input-triggered switches. The latter class of DNA-host conjugates have been demonstrated to precisely control protein activity, and have also been used as modulable catalysts and versatile biosensors.

Abstract
Technologies that detect and image RNA have illuminated the complex roles played by RNA, redefining the traditional and superficial role first outlined by the central dogma of biology. Because there is such a wide diversity of RNA structure arising from an assortment of functions within biology, a toolbox of approaches have emerged for investigation of this important class of biomolecules. These methods are necessary to detect and elucidate the localization and dynamics of specific RNAs and in doing so unlock our understanding of how RNA dysregulation leads to disease. Current methods for detecting and imaging RNA include in situ hybridization techniques, fluorescent aptamers, RNA binding proteins fused to fluorescent reporters, and covalent labeling strategies. Because of the inherent diversity of these methods, each approach comes with a set of strengths and limitations that leave room for future improvement. This perspective seeks to highlight the most recent advances and remaining challenges for the wide-ranging toolbox of technologies that illuminate RNA's contribution to cellular complexity.

Abstract
Nucleic acid directed bioorthogonal reactions offer the fascinating opportunity to unveil and redirect a plethora of intracellular mechanisms. Nano- to picomolar amounts of specific RNA molecules serve as templates and catalyze the selective formation of molecules that 1) exert biological effects, or 2) provide measurable signals for RNA detection. Turnover of reactants on the template is a valuable asset when concentrations of RNA templates are low. The idea is to use RNA-templated reactions to fully control the biodistribution of drugs and to push the detection limits of DNA or RNA analytes to extraordinary sensitivities. Herein we review recent and instructive examples of conditional synthesis or release of compounds for in cellulo protein interference and intracellular nucleic acid imaging.

Abstract
Oligonucleotide-templated reactions are valuable tools for nucleic acid sensing both in vitro and in vivo. They are typically carried out under conditions that make any reaction in the absence of template highly unfavorable (most commonly by using a low concentration of reactants), which has a negative impact on the detection sensitivity. Herein, we report a novel platform for fluorogenic oligonucleotide-templated reactions between peptide nucleic acid probes embedded within permeable agarose and alginate hydrogels. We demonstrate that under conditions of restricted mobility (that is, limited diffusion), non-specific interactions between probes are prevented, thus leading to lower background signals. When applied to nucleic acid sensing, this accounts for a significant increase in sensitivity (that is, lower limit of detection). Optical nucleic acid sensors based on fluorogenic peptide nucleic acid probes embedded in permeable, physically crosslinked, alginate beads were also engineered and proved capable of detecting DNA concentrations as low as 100 pm.

Abstract
A chemical reaction that is triggered by a specific RNA molecule might provide opportunities for the design of artificial feedback loops. We envision a peptidyl transfer reaction in which mRNA encoding an antiapoptotic protein would instruct the synthesis of apoptosis-inducing peptides. In this study, we used the RNA-programmed synthesis of a 16-mer peptide derived from the BH3 domain of the protein Bak, which inhibits the antiapoptotic protein Bcl-xL . The reaction involves the transfer of a thioester-linked donor peptide fragment from one PNA conjugate to an acceptor peptide-PNA conjugate. We asked two key questions. What are the chemical requirements that allow RNA-templated synthesis of a 16-mer peptide to proceed at lower (nanomolar) concentrations of RNA, that is, the concentration range found in cancer cells? Will such reactions provide sufficient amounts of peptide product and sufficient affinity to interfere with the targeted protein-protein interaction? Perhaps surprisingly, the lengths of the peptides involved in peptidyl transfer chemistry have little effect on the achievable rate enhancements. However, the nature of the thioester C terminus, the distance between the targeted template annealing sites, and template affinity play important roles. The investigation revealed guidelines for the reaction design for peptidyl transfer with low amounts (1-10 nm) of RNA, yet still provide sufficient product to antagonize a protein-protein interaction.

Abstract
Switchable β-cyclodextrin (β-CD)-induced hydrolysis of m-tert-butylphenyl acetate is demonstrated in the presence of supramolecular β-CD/adamantane oligonucleotide scaffolds. In one system, a duplex between a β-CD-functionalized nucleic acid and an adamantane-nucleic acid leads to a switchable catalytic system. In a second system, a β-CD/adamantane duplex is cooperatively generated by K(+)-stabilized G-quadruplex units. The binding of hemin to the second system yields a bifunctional DNA scaffold with alternate catalytic functions.

Abstract
Bioorthogonal reactions have been widely used over the last 10 years for imaging, detection, diagnostics, drug delivery, and biomaterials. Tetrazine reactions are a recently developed class of inverse electron-demand Diels-Alder reactions used in bioorthogonal applications. Given their rapid tunable reaction rate and highly fluorogenic properties, tetrazine bioorthogonal reactions have come to be considered highly attractive tools for elucidating biological functions and messages in vitro and in vivo. In this chapter, we present recent advances expanding the scope of precursor reactivity and we introduce new biomedical methodology based on bioorthogonal tetrazine chemistry. We specifically highlight novel applications for different kinds of biomolecules, including nucleic acid, protein, antibodies, lipids, glycans, and bioactive small molecules, in the areas of imaging, detection, and diagnostics. We also briefly present other recently developed inverse electron-demand Diels-Alder bioorthogonal reactions. Lastly, we consider future directions and potential roles that inverse electron-demand Diels-Alder reactions may play in the fields of bioorthogonal and biomedical chemistry.

Abstract
Fluorescently labeled proteins enable the microscopic imaging of protein localization and function in live cells. In labeling reactions targeted against specific tag sequences, the size of the fluorophore-tag is of major concern. The tag should be small to prevent interference with protein function. Furthermore, rapid and covalent labeling methods are desired to enable the analysis of fast biological processes. Herein, we describe the development of a method in which the formation of a parallel coiled coil triggers the transfer of a fluorescence dye from a thioester-linked coil peptide conjugate onto a cysteine-modified coil peptide. This labeling method requires only small tag sequences (max 23 aa) and occurs with high tag specificity. We show that size matching of the coil peptides and a suitable thioester reactivity allow the acyl transfer reaction to proceed within minutes (rather than hours). We demonstrate the versatility of this method by applying it to the labeling of different G-protein coupled membrane receptors including the human neuropeptide Y receptors 1, 2, 4, 5, the neuropeptide FF receptors 1 and 2, and the dopamine receptor 1. The labeled receptors are fully functional and able to bind the respective ligand with high affinity. Activity is not impaired as demonstrated by activation, internalization, and recycling experiments.

Abstract
The programmability of oligonucleotide hybridization offers an attractive platform for the design of assemblies with emergent properties or functions. Developments in DNA nanotechnologies have transformed our thinking about the applications of nucleic acids. Progress from designed assemblies to functional outputs will continue to benefit from functionalities added to the nucleic acids that can participate in reactions or interactions beyond hybridization. In that respect, peptide nucleic acids (PNAs) are interesting because they combine the hybridization properties of DNA with the modularity of peptides. In fact, PNAs form more stable duplexes with DNA or RNA than the corresponding natural homoduplexes. The high stability achieved with shorter oligomers (an 8-mer is sufficient for a stable duplex at room temperature) typically results in very high sequence fidelity in the hybridization with negligible impact of the ionic strength of the buffer due to the lack of electrostatic repulsion between the duplex strands. The simple peptidic backbone of PNA has been shown to be tolerant of modifications with substitutions that further enhance the duplex stability while providing opportunities for functionalization. Moreover, the metabolic stability of PNAs facilitates their integration into systems that interface with biology. Over the past decade, there has been a growing interest in using PNAs as biosupramolecular tags to program assemblies and reactions. A series of robust templated reactions have been developed with functionalized PNA. These reactions can be used to translate DNA templates into functional polymers of unprecedented complexity, fluorescent outputs, or bioactive small molecules. Furthermore, cellular nucleic acids (mRNA or miRNA) have been harnessed to promote assemblies and reactions in live cells. The tolerance of PNA synthesis also lends itself to the encoding of small molecules that can be further assembled on the basis of their nucleic acid sequences. It is now well-established that hybridization-based assemblies displaying two or more ligands can interact synergistically with a target biomolecule. These assemblies have now been shown to be functional in vivo. Similarly, PNA-tagged macromolecules have been used to prepare bioactive assemblies and three-dimensional nanostructures. Several technologies based on DNA-templated synthesis of sequence-defined polymers or DNA-templated display of ligands have been shown to be compatible with reiterative cycles of selection/amplification starting with large libraries of DNA templates, bringing the power of in vitro evolution to synthetic molecules and offering the possibility of exploring uncharted molecular diversity space with unprecedented scope and speed.

Abstract
Three LNA-based mercaptoacetamido-linked nonionic nucleoside dimers TL-S-T, T-S-TL, and TL-S-TL have been synthesized by HOBT and HBTU catalyzed condensation of silyl-protected 2-S-(thymidin-5 '-yl)mercaptoacetic acid or 2-S-(2 '-O,4 '-C-methylenethymidin-5 '-yl)mercaptoacetic acid with 3 '-amino-3 '-deoxy-5 '-O-DMT-2 '-O,4 '-C-methylenethymidine or with 3 '-amino-3 '-deoxy-5 '-O-DMT-β-thymidine followed by desilylation of the protected dimers. The 3 '-O-phosphoramidite derivative of one of the nucleoside dimers was successfully prepared by condensation with [P(-Cl)(-OCH2CH2CN)-N(iPr)2}] in DCM in the presence of N,N-diisopropylethylamine (DIPEA), which is a building block for the preparation of mercaptoacetamido-linked oligonucleotides of therapeutic applications.

Abstract
Tetrazine ligations have proven to be a powerful bioorthogonal technique for the detection of many labeled biomolecules, but the ligating nature of these reactions can limit reaction turnover in templated chemistry. We have developed a transfer reaction between 7-azabenzonorbornadiene derivatives and fluorogenic tetrazines that facilitates turnover amplification of the fluorogenic response in nucleic acid-templated reactions. Fluorogenic tetrazine-mediated transfer (TMT) reaction probes can be used to detect DNA and microRNA (miRNA) templates to 0.5 and 5 pM concentrations, respectively. The endogenous oncogenic miRNA target mir-21 could be detected in crude cell lysates and detected by imaging in live cells. Remarkably, the technique is also able to differentiate between miRNA templates bearing a single mismatch with high signal to background. We imagine that TMT reactions could find wide application for amplified fluorescent detection of clinically relevant nucleic acid templates.

Abstract
Sensing technologies based on Peptide Nucleic Acids (PNAs) and oligonucleotide-templated chemistry are perfectly suited for biomedical applications (e.g., diagnosis, prognosis and stratification of diseases) and could compete well with more traditional amplification technologies using expensive dual-labelled oligonucleotide probes. PNAs can be easily synthesised and functionalised, are more stable and are more responsive to point-mutations than their DNA counterpart. For these reasons, fluorogenic PNAs represent an interesting alternative to DNA-based molecular beacons for sensing applications in a cell-free environment, where cellular uptake is not required.

Abstract
Native chemical ligation (NCL) is a powerful method for the convergent synthesis of proteins and peptides. In its original format, NCL between a peptide containing a C-terminal thioester and another peptide offering an N-terminal cysteine has been used to enable protein synthesis of unprotected peptide fragments. However, the applications of NCL extend beyond the scope of protein synthesis. For instance, NCL can be put under the control of template molecules. In such a scenario, NCL enables the design of conditional reaction systems in which, peptide bond formation occurs only when a specific third party molecule is present. In this review, we will show how templates can be used to control the reactivity and chemoselectivity of NCL reactions. We highlight peptide and nucleic-acid-templated NCL reactions and discuss potential applications in nucleic acid diagnosis, origin-of-life studies and gene-expression-specific therapies.

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
We propose here a new amplifying strategy that uses hybridization chain reaction (HCR) to detect specific sequences of DNA, where stable DNA monomers assemble on the magnetic beads only upon exposure to a target DNA. Briefly, in the HCR process, two complementary stable species of hairpins coexist in solution until the introduction of initiator reporter strands triggers a cascade of hybridization events that yield nicked double helices analogous to alternating copolymers. Moreover, a "sandwich-type" detection strategy is employed in our design. Magnetic beads, which are functionalized with capture DNA, are reacted with the target, and sandwiched with the above nicked double helices. Then, chemiluminescence (CL) detection proceeds via an instantaneous derivatization reaction between a specific CL reagent, 3,4,5-trimethoxylphenylglyoxal (TMPG), and the guanine nucleotides within the target DNA, reporter strands and DNA monomers for the generation of light. Our results clearly show that the amplification detection of specific sequences of DNA achieves a better performance (e.g. wide linear response range, low detection limit, and high specificity) as compared to the traditional sandwich type (capture/target/reporter) assays. Upon modification, the approach presented could be extended to detect other types of targets. We believe that this simple technique is promising for improving medical diagnosis and treatment.

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
Template driven chemical ligation of fluorogenic probes represents a powerful method for DNA and RNA detection and imaging. Unfortunately, previous techniques have been hampered by requiring chemistry with sluggish kinetics and background side reactions. We have developed fluorescent DNA probes containing quenched fluorophore-tetrazine and methyl-cyclopropene groups that rapidly react by bioorthogonal cycloaddition in the presence of complementary DNA or RNA templates. Ligation increases fluorescence with negligible background signal in the absence of hybridization template. Reaction kinetics depend heavily on template length and linker structure. Using this technique, we demonstrate rapid discrimination between single template mismatches both in buffer and cell media. Fluorogenic bioorthogonal ligations offer a promising route towards the fast and robust fluorescent detection of specific DNA or RNA sequences.

Abstract
DNA templated fluorogenic reactions have been used as a diagnostic tool for the sequence specific detection of nucleic acids; and it has been shown that the native chemical ligation between thioester- and 1,2-aminothiol-modified PNA probes is amongst the most selective DNA detection methods reported. We explored whether a DNA templated reaction can be interfaced with the polymerase chain reaction (PCR). This endeavor posed a significant challenge. The reactive groups involved must be sufficiently stable to tolerate the high temperature applied in the PCR process. Nevertheless, the ligation reaction must proceed very rapidly and sequence specifically within the short time available in the annealing and primer extension steps before denaturation is used after approx. 1 min to commence the next PCR cycle. This required a careful optimization of the ternary complex architecture as well as adjustments of probe length and probe reactivities. Our results point to the prime importance of the ligation architecture. We show that once suitable annealing sites have been identified less reactive probe sets may be preferable if sequence specificity is of major concern. The reactivity tuning enabled the development of an in-PCR ligation, which was used for the single nucleotide specific typing of the V600E (T1799A) point mutation in the human BRaf gene. Showcasing the efficiency and sequence specificity of native chemical PNA ligation, attomolar template proofed sufficient to trigger signal while a 1000-fold higher load of single mismatched template failed to induce appreciable signal.

Abstract
Reactions templated by cellular nucleic acids are attractive for nucleic acid sensing or responsive systems. Herein we report the use of a photocatalyzed reductive cleavage of an immolative linker to unmask a rhodamine fluorophore, and its application to miRNA imaging. The reaction was found to proceed with a very high turnover (>4000) and provided reliable detection down to 5 pM of template by using γ-serine-modified peptide nucleic acid (PNA) probes. The reaction was used for the selective detection of miR-21 in BT474 cells and miR-31 in HeLa cells following irradiation for 30 min. The probes were introduced by using reversible permeation with streptolysin-O (SLO) or a transfection technique.

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.
