Abstract
The short-range charge transfer of DNA base triplets has wide application prospects in bioelectronic devices for identifying DNA bases and clinical diagnostics, and the key to its development is to understand the mechanisms of short-range electron dynamics. However, tracing how electrons are transferred during the short-range charge transfer of DNA base triplets remains a great challenge. Here, by means of ab initio molecular dynamics and Ehrenfest dynamics, the nuclear-electron interaction in the thymine-adenine-thymine (TAT) charge transfer process is successfully simulated. The results show that the electron transfer of TAT has an oscillating phenomenon with a period of 10 fs. The charge density difference proves that the charge transfer proportion is as high as 59.817% at 50 fs. The peak position of the hydrogen bond fluctuates regularly between -0.040 and -0.056. The time-dependent Marcus-Levich-Jortner theory proves that the vibrational coupling between nucleus and electron induces coherent electron transfer in TAT. This work provides a real-time demonstration of the short-range coherent electron transfer of DNA base triplets and establishes a theoretical basis for the design and development of novel biological probe molecules.

Abstract
![]()
Fluorescent DNA probes were prepared in a modular approach
using
the “click” post-synthetic modification strategy. The
new glycol-based module and DNA building block place just two carbons
between the phosphodiester bridges and anchor the dye by an additional
alkyne group. This creates a stereocenter in the middle of this artificial
nucleoside substitute. Both enantiomers and a variety of photostable
cyanine–styryl dyes as well as thiazole orange derivatives
were screened as “clicked” conjugates in different surrounding
DNA sequences. The combination of the (S)-configured
DNA anchor and the cyanylated cyanine–styryl dye shows the
highest fluorescence light-up effect of 9.2 and a brightness of approximately
11,000 M–1 cm–1. This hybridization
sensitivity and fluorescence readout were further developed utilizing
electron transfer and energy transfer processes. The combination of
the hybridization-sensitive DNA building block with the nucleotide
of 5-nitroindole as an electron acceptor and a quencher increases
the light-up effect to 20 with the DNA target and to 15 with the RNA
target. The fluorescence readout could significantly be enhanced to
values between 50 and 360 by the use of energy transfer to a second
DNA probe with commercially available dyes, like Cy3.5, Cy5, and Atto590,
as energy acceptors at the 5′-end. The latter binary probes
shift the fluorescent readout from the range of 500–550 nm
to the range of 610–670 nm. The optical properties make these
fluorescent DNA probes potentially useful for RNA imaging. Due to
the strong light-up effect, they will not require washing procedures
and will thus be suitable for live-cell imaging.

Abstract
Bisulfite (HSO3-) has been widely used as an important food additive in daily life. Furthermore, a normal amount of HSO3- plays a significant role in biological systems. However, excessive intake of HSO3- will lead to a variety of diseases. Therefore, it is of great significance to develop an efficient fluorescent probe that can be used for detection of HSO3- in biological systems and food samples. In this work, a near-infrared (NIR) emitted fluorescent probe (SZY) based on hemicyanine dye was successfully synthesized and applied to detect HSO3- in several food samples and live animals. The proposed nucleophilic addition sensing mechanism of SZY towards HSO3- has been confirmed by 1H NMR titration, high resolution mass spectrometry (HR-MS) and density functional theory (DFT) theoretical computation. The HSO3--induced nucleophilic reaction with α,β-unsaturated C=C binding of SZY results in the dramatic decline of the UV-vis absorption and remarkable quenching of the fluorescence emission. SZY features the advantages of near infrared emission (centered at 720 nm), high water solubility (in 98% aqueous solution), fast response time (50 s), large Stokes shift (244 nm) and low cytotoxicity. The probe SZY was successfully applied to image of HSO3- in live nude mouse and adult zebrafish. Semi-quantitatively analyzing the HSO3- level by "naked eye" in several food samples including canned fruit, white wine, white sugar and jasmine tea drinks has been realized by the colorimetric method.

Abstract
Functional nucleic acids with the capability of generating fluorescence in response to hybridization events, microenvironment or structural changes are valuable as structural probes and chemical sensors. We now demonstrate the enzyme-assisted preparation of nucleic acids possessing multiple thiazole orange (TO) dyes and their fluorescent behavior, that show a spectral change from the typical monomer emission to the excimer-type red-shifted emission. We found that the fluorescent response and emission wavelength of the TO dyes were dependent on both the state of the DNA structure (single- or double-stranded DNA) and the arrangement of the TO dyes. We showed that the fluorescent behavior of the TO dyes can be applied for the detection of RNA molecules, suggesting that our approach for preparing the fluorescent nucleic acids functionalized with multiple TO dyes could be useful to design a fluorescence bioimaging and detection technique of biomolecules.

Abstract
Fluorescent sensing of biomolecules has served as a revolutionary tool for studying and better understanding various biological systems. Therefore, it has become increasingly important to identify fluorescent building blocks that can be easily converted into sensing probes, which can detect specific targets with increasing sensitivity and accuracy. Over the past 30 years, thiazole orange (TO) has garnered great attention due to its low fluorescence background signal and remarkable 'turn-on' fluorescence response, being controlled only by its intramolecular torsional movement. These features have led to the development of numerous molecular probes that apply TO in order to sense a variety of biomolecules and metal ions. Here, we highlight the tremendous progress made in the field of TO-based sensors and demonstrate the different strategies that have enabled TO to evolve into a versatile dye for monitoring a collection of biomolecules.

Abstract
Devising fluorescence-based turn-on probes for the specific and sensitive detection of Heparin is of utmost clinical importance. In this contribution, we have identified a molecular rotor based asymmetric cyanine probe, thiazole orange (TO), which enables an efficient colorimetric and fluorimetric detection of Heparin. TO undergoes the formation of emissive H-aggregates upon interaction with Heparin that display an impressive emission enhancement of ~22 fold together with drastic changes in the absorption spectra that yields a prominent colour change in the solution from orange to yellow. These seldom reported emissive H-aggregates of TO, serve as an efficient platform for Heparin detection with a LOD of 19 nM, fluorometrically and 34 nM, colorimetrically. The TO-Heparin complex is also accompanied by a large change in the excited-state lifetime. The TO-Heparin complex has been further utilized for the detection of Protamine, which is the only medically affirmed antitoxin of Heparin. Overall, our sensing system offers several advantages, such as, simple, dual read-out, economic and specific detection of Heparin with longer excitation and emission wavelength, rapid naked eye detection and utilizes an in-expensive commercially available fluoprophore, TO. Most importantly, our sensing system also displays a good performance in the biologically complex human serum matrix.

Abstract
The development of new methods for rapid and effective detection of bisulfite (HSO3-) in food samples and imaging of HSO3- intake in animals is of significant importance due to the key roles of HSO3- in food quality assurance and community health. In this work, a new responsive fluorescence probe, EQC, is reported for the quantitative detection of HSO3- in food samples and visualization of HSO3- intake in animals. Upon addition of HSO3-, the UV-vis absorption and red emission of EQC were significantly decreased within 120 s. The changes in absorption and emission spectra of EQC were rationalized by theoretical computations. The proposed reaction mechanism of EQC with HSO3- was confirmed by high-resolution mass spectrometry (HRMS) and spectroscopic titration measurements. EQC has the advantages of high sensitivity, selectivity (a detection limit of 18.1 nM), and fast response toward HSO3-, which enable rapid and effective HSO3- detection in buffer solution. The practical applications of EQC were demonstrated by the detection of HSO3- in food samples and the imaging of HSO3- intake in live animals.

Abstract
The increasing importance assigned to RNA dynamics in cells and tissues calls for probe molecules that enable fluorescence microscopy imaging in live cells. To achieve this goal, fluorescence dyes are conjugated with oligonucleotides so as to provide strong emission upon hybridization with the target molecule. The impressive 10(3)-fold fluorescence intensification observed when DNA stains such as thiazole orange (TO) interact with double-stranded DNA is intriguing and prompted the exploration of oligonucleotide conjugates. However, nonspecific interactions of DNA stains with polynucleotides tend to increase background, which would affect the contrast achievable in live-cell imaging. This Account describes the development of DNA-stain-labeled hybridization probes that provide high signal-to-background. We focus on our contributions in context with related advances from other laboratories. The emphasis will be on the requirements of RNA imaging in live cells. To reduce background, intercalator dyes such as TO were appended to peptide nucleic acid (PNA), which is less avidly recognized by DNA stains than DNA/RNA. Constraining the TO dye as a nucleobase surrogate in "forced intercalation (FIT) probes" improved the target specificity, presumably by helping to prevent unspecific interactions. The enforcement of TO intercalation between predetermined base pairs upon formation of the probe-target duplex provided for high brightness and enabled match/mismatch selectivity beyond stringency of hybridization. We show examples that highlight the use of PNA FIT probes in the imaging of mRNA, miRNA, and lncRNA in living cells. The "FIT approach" was recently extended to DNA probes. Signal brightness can become limiting when low-abundance targets ought to be visualized over cellular autofluorescence. We discuss strategies that further the brightness of signaling by FIT probes. Multilabeling with identical dyes does not solve the brightness issue. To avoid self-quenching, we combined two different yet spectrally overlapping fluorescent base surrogates. A hybridization-sensitive dye serves as a light collector that transfers energy to a brightly emissive acceptor dye. To improve the brilliance of single-dye probes, the "TO-nucleotide" was accompanied by an adjacent locked nucleic acid (LNA) unit. The LNA-constrained FIT probes are responsive and bright, enabling the tracking of mRNA transport in living tissue. We also show that the color repertoire of FIT probes is not restricted to the green-emissive TO but can be expanded to cyan and red. A new base surrogate (4,4-linked bisquinoline) provided up to 195-fold enhancement of the fluorescence.

Abstract
Oligonucleotides with 3-ethynyl-5-nitroindole and 3-octadiynyl-5-nitroindole 2'-deoxyribonucleosides were prepared by solid-phase synthesis. To this end, nucleoside phosphoramidites with clickable side chains were synthesized. The 3-ethynylated 5-nitroindole nucleoside was hydrated during automatized DNA synthesis to 3-acetyl-5-nitroindole 2'-deoxyribonucleoside. Side product formation was circumvented by triisopropylsilyl protection of the ethynyl side chain and was removed with TBAF after oligonucleotide synthesis. All compounds with a clickable 5-nitroindole skeleton show universal base pairing and can be functionalized with almost any azide in any position of the DNA chain. Functionalization of the side chain with 1-azidomethylpyrene afforded click adducts in which the fluorescence was quenched by the 5-nitroindole moieties. However, fluorescence was slightly recovered during duplex formation. Oligonucleotides with a pyrene residue and a long linker arm are stabilized over those with non-functionalized side chains. From the UV red shift of the pyrene residue in oligonucleotides and modelling studies, pyrene intercalation was established for the long linker adduct showing increased duplex stability over those with a short side chain.

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
In this study the position of the thiazole orange derivative in triplex-forming oligonucleotides (TFOs) is varied and the fluorescence of the resulting complexes with DNA duplexes, single-stranded DNAs and RNAs are evaluated. Under similar conditions single attachment of the TO-dye to 2'-O-propargyl nucleotides in the TFOs (assembly dependent fluorescence enhancing nucleic acids, AFENA) led to probes with low fluorescent intensity in the single-stranded state with fluorescence quantum yield (ΦF ) of 0.9 %-1.5 %. Significant increase in fluorescence intensity was detected after formation of DNA triplexes (ΦF =23.5 %-34.9 %). Under similar conditions, Watson-Crick-type duplexes formed by the probes with single stranded (ss) RNA and ssDNA showed lower fluorescence intensities. Bugle insertions of twisted intercalating nucleic acid (TINA) monomers were shown to improve the fluorescent characteristics of GT/GA-containing antiparallel AFENA-TFOs. Self-aggregation of TFOs caused by guanosines was eliminated by TINA insertion which also promoted DNA triplex formation at pH 7.2. Importantly these AFENA-TINA-TFOs can bind to the duplex in the presence of complementary RNA at 37 °C.

Abstract
A methodology for the site-specific attachment of fluorophores to the backbone of pyrrolidinyl peptide nucleic acids (PNAs) with an α/β-backbone derived from D-prolyl-(1S,2S)-2-aminocyclopentanecarboxylic acid (acpcPNA) has been developed. The strategy involves a postsynthetic reductive alkylation of the aldehyde-containing labels onto the acpcPNA that was previously modified with (3R,4S)-3-aminopyrrolidine-4-carboxylic acid on the solid support. The reductive alkylation reaction is remarkably efficient and compatible with a range of reactive functional groups including Fmoc-protected amino, azide, and alkynes. This allows further attachment of readily accessible carboxyl-, alkyne-, or azide-containing labels via amide bond formation or Cu-catalyzed azide-alkyne cycloaddition (CuAAC, also known as click chemistry). The label attached in this way does not negatively affect the affinity and specificity of the pairing of the acpcPNA to its DNA target. Applications of this methodology in creating self-reporting pyrene- and thiazole orange-labeled acpcPNA probes that can yield a change in fluorescence in response to the presence of the correct DNA target have also been explored. A strong fluorescence enhancement was observed with thiazole orange-labeled acpcPNA in the presence of DNA. The specificity could be further improved by enzymatic digestion with S1 nuclease, providing a 9- to 60-fold fluorescence enhancement with fully complementary DNA and a less than 3.5-fold enhancement with mismatched DNA targets.

Abstract
Fluorescently labeled oligonucleotides are commonly employed as probes to detect specific DNA or RNA sequences in homogeneous solution. Useful probes should experience strong increases in fluorescent emission upon hybridization with the target. We developed dual labeled peptide nucleic acid probes, which signal the presence of complementary DNA or RNA by up to 450-fold enhancements of fluorescence intensity. This enabled the very sensitive detection of a DNA target (40 pM LOD), which was detectable at less than 0.1% of the beacon concentration. In contrast to existing DNA-based molecular beacons, this PNA-based method does not require a stem sequence to enforce dye-dye communication. Rather, the method relies on the energy transfer between a "smart" thiazole orange (TO) nucleotide, which requires formation of the probe-target complex in order to become fluorescent, and terminally appended acceptor dyes. To improve upon fluorescence responsiveness the energy pathways were dissected. Hydrophobic, spectrally mismatched dye combinations allowed significant (99.97%) decreases of background emission in the absence of a target. By contrast, spectral overlap between TO donor emission and acceptor excitation enabled extremely bright FRET signals. This and the large apparent Stokes shift (82 nm) suggests potential applications in the detection of specific RNA targets in biogenic matrices without the need of sample pre-processing prior to detection.

Abstract
The rapid and convenient method for identification of all kinds of G-quadruplex is highly desirable. In the present study, a novel colorimetric indicator for a vast variety of G-quadruplex was designed and synthesized on the basis of thiazole orange and isaindigotone skeleton. Its distinct color change enables label-free visual detection of G-quadruplexes, which is due to the disassembly of dye H-aggregates to monomers. This specific detection of G-quadruplex arises from its end-stacking interaction with G-quartet. On the basis of this universal indicator, a facile approach for large-scale identification of G-quadruplex was developed.

Abstract
Because of their environment-sensitive fluorescence quantum yields, base analogues such as 2-aminopurine (2AP), 6-methylisoxanthopterin (6-MI), and 3-methylisoxanthopterin (3-MI) are widely used in nucleic-acid folding and catalysis assays. Emissions from these guanine mimics are quenched by base-stacking interactions and collisions with purine residues. Fluorescent base analogues that remain highly emissive in folded nucleic acids can provide sensitive means to differentiate DNA/RNA structures by participating in energy transfer from proximal ensembles of unmodified nucleobases. The development of new, highly emissive guanine mimics capable of proper base stacking and base-pairing interactions is an important prerequisite to this approach. Here we report a comparison of the most commonly used probe, 2-aminopurine (2AP), to 8-(2-pyridyl)-2'-deoxyguanosine (2PyG). The photophysical properties of these purine derivatives are very different. 2PyG exhibits enhanced fluorescence quantum yields upon its incorporation into folded nucleic acids--approximately 50-fold brighter fluorescence intensity than 2AP in the context of duplex DNA. Due to its bright fluorescence and compatibility with proper DNA folding, 2PyG can be used to accurately quantify energy-transfer efficiencies, whereas 2AP is much less sensitive to structure-specific trends in energy transfer. When using nucleoside monomers, Stern-Volmer plots of 2AP fluorescence revealed upward curvature of F(0) /F upon titration of guanosine monophoshate (GMP), whereas 2PyG exhibited unusual downward curvature of F(0) /F that resulted in a recovery of fluorescence at high GMP concentrations. These results are consistent with the trends observed for 2PyG- and 2AP-containing oligonucleotides, and furthermore suggest that solutions containing high concentrations of GMP can, in some ways, mimic the high local nucleobase densities of folded nucleic acids.

Abstract
We have synthesized fluorescent DNA duplexes featuring multiple thiazole orange (TO) intercalating dyes covalently attached to the DNA via a triazole linkage. The intercalating dyes stabilize the duplex against thermal denaturation and show bright fluorescence in the green region of the spectrum. The emission color can be changed to orange or red by addition of energy-accepting Cy3 or Cy5 dyes attached covalently to the DNA duplex. The dye-modified DNA duplexes were then attached to a secondary antibody for intracellular fluorescence imaging of centrosomes in Drosophila embryos. Bright fluorescent foci were observed at the centrosomes in both the donor (TO) and acceptor (Cy5) channels, because the energy transfer efficiency is moderate. Monitoring the Cy5 emission channel significantly minimized the background signal because of the large shift in emission wavelength allowed by energy transfer.

Abstract
The azides 1 and 2 bearing a phenoxazinium and a coumarin fluorophore, respectively, were applied in postsynthetic "click"-type bioconjugation and coupled to oligonucleotides modified with alkyne groups using two alternative approaches: (i) as a nucleotide modification at the 2'-position of uridine and (ii) as a nucleotide substitution using (S)-(-)-3-amino-1,2-propanediol as an acyclic linker between the phosphodiester bridges. The corresponding alkynylated phosporamidites 3 and 6 were used as DNA building blocks for the preparation of alkyne-bearing DNA duplexes. The base pairs adjacent to the site of modification and the base opposite to it were varied in the DNA sequences. The modified duplexes were investigated by UV/vis absorption spectroscopy (including melting temperatures) and fluorescence spectroscopy in order to study the different optical properties of the two chromophores and to evaluate their potential for bioanalytical applications. The sequence-selective fluorescence quenching of phenoxazinium 1 differs only slightly and does not depend on the type of modification, meaning whether it has been attached to the 2'-position of uridine or as DNA base surrogate using the acyclic glycol linker. The 2'-chromophore-modified uridine still recognizes adenine as the counterbase, and the duplexes exhibit a sufficient thermal stability that is comparable to that of unmodified duplexes. Thus, the application of the 2'-modification site of uridine is preferred in comparison to glycol-assisted DNA base surrogates. Accordingly, the coumarin dye azide 2 was attached only to the 2'-position of uridine. The significant Stokes shift of approximately 100 nm and the good quantum yields make the coumarin chromophore a powerful fluorescent label for nucleic acids.

Probe molecules that enable the detection of specific DNA sequences are used in diagnostic and basic research. Most methods rely on the specificity of hybridization reactions, which complicates the detection of single base mutations at low temperature. Significant efforts have been devoted to the development of oligonucleotides that allow discrimination of single base mutations at temperatures where both the match and the mismatch probe-target complexes coexist. Oligonucleotides that contain environmentally sensitive fluorescence dyes such as thiazole orange (TO) provide single nucleotide specific fluorescence. However, most previously reported dye-DNA conjugates showed only little if any difference between the fluorescence of the single and the double stranded state. Here, we introduce a TO-containing acyclic nucleotide, which is coupled during automated oligonucleotide synthesis and provides for the desired fluorescence-up properties. The study reveals the conjugation mode as the most important issue. We show a design that leads to low fluorescence of the unbound probe (background) yet permits TO to adopt fluorescent binding modes after the probe-target complex has formed. In these probes, TO replaces a canonical nucleobase. Of note, the fluorescence of the "TO-base" remains low when a base mismatch is positioned in immediate vicinity.

Abstract
The Nile Blue chromophore was incorporated into oligonucleotides using "click" chemistry for the postsynthetic modification of oligonucleotides. These were synthesized using DNA building block 3 bearing an alkyne group and reacted with the azide 4. (R)-3-amino-1,2-propanediol was applied as the linker between the phosphodiester bridges. Two sets of DNA duplexes were prepared. One set carried the chromophore in an A-T environment, the second set in a G-C environment. Both were characterized by optical spectroscopy. Sequence-dependent fluorescence quenching was applied as a sensitive tool to compare the stacking interactions with respect to the chirality of the acyclic linker attachment. The results were compared to recent results from duplexes that carried the Nile Blue label in a sequentially and structurally identical context, except for the opposite chirality of the linker ((S)-3-amino-1,2-propandiol). Only minor, negligible differences were observed. Melting temperatures, UV-vis absorption spectra together with fluorescence quenching data indicate that Nile Blue stacks perfectly between the adjacent base pairs regardless of whether it has been attached via an S- or R-configured linker. This result was supported by geometrically optimized DNA models.
