Abstract
Solid-state transistor sensors that can detect biomolecules in real time are highly attractive for emerging bioanalytical applications. However, combining upscalable manufacturing with the required performance remains challenging. Here, an alternative biosensor transistor concept is developed, which relies on a solution-processed In2 O3 /ZnO semiconducting heterojunction featuring a geometrically engineered tri-channel architecture for the rapid, real-time detection of important biomolecules. The sensor combines a high electron mobility channel, attributed to the electronic properties of the In2 O3 /ZnO heterointerface, in close proximity to a sensing surface featuring tethered analyte receptors. The unusual tri-channel design enables strong coupling between the buried electron channel and electrostatic perturbations occurring during receptor-analyte interactions allowing for robust, real-time detection of biomolecules down to attomolar (am) concentrations. The experimental findings are corroborated by extensive device simulations, highlighting the unique advantages of the heterojunction tri-channel design. By functionalizing the surface of the geometrically engineered channel with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody receptors, real-time detection of the SARS-CoV-2 spike S1 protein down to am concentrations is demonstrated in under 2 min in physiological relevant conditions.

Abstract
10-23 DNAzyme is a small catalytic DNA molecule. Studies on its conformation in solution are critical for understanding its catalytic mechanism and functional optimization. Based on our previous research, two fluorescent nucleoside analogues 1 and 2 were designed for the introduction of a pyrenyl group at one of the five dA residues in the catalytic core and the unpaired adenosine residue in its full-DNA substrate, respectively. Ten pyrenyl-pyrenyl pairs are formed in the DNAzyme-substrate complexes in solution for sensing the spacial positions of the five dA residues relative to the cleavage site using fluorescence spectra. The position-dependent quenching effect of pyrene emission fluorescence by nucleobases, especially the pyrenyl-pyrenyl interaction, was observed for some positions. The adenine residues in the 3'-part of the catalytic loop seem to be closer to the cleavage site than the adenine residues in the 5'-part, which is consistent with the molecular dynamics simulation result. The catalytic activities and Tm changes also confirmed the effect of the pyrenyl-nucleobase and pyrenyl-pyrenyl pair interactions. Together with functional group mutations, catalytically relevant nucleobases will be identified for understanding the catalytic mechanism of 10-23 DNAzyme.

Abstract
Oligonucleotide probes labeled with pyrene pairs that form excimers have a number of applications in hybridization analysis of nucleic acids. A long excited state lifetime, large Stokes shift, and chemical stability make pyrene excimer an attractive fluorescent label. Here we report synthesis of chiral phosphoramidite building blocks based on (R)-4-amino-2,2-dimethylbutane-1,3-diol, easily available from an inexpensive d-(-)-pantolactone. 1-Pyreneacetamide, 1-pyrenecarboxamide, and DABCYL derivatives have been used in preparation of molecular beacon (MB) probes labeled with one or two pyrenes/quenchers. We observed significant difference in the excimer emission maxima (475-510 nm; Stokes shifts 125-160 nm or 7520-8960 cm-1) and excimer/monomer ratio (from 0.5 to 5.9) in fluorescence spectra depending on the structure and position of monomers in the pyrene pair. The pyrene excimer formed by two rigid 1-pyrenecarboxamide residues showed the brightest emission. This is consistent with molecular dynamics data on excimer stability. Increase of the excimer fluorescence for MBs after hybridization with DNA was up to 24-fold.

Abstract
The pyrene-based RNA-fluorescence label 2-(2-pyrenylethynyl) adenosine (2PyA) shows triexponential fluorescence, which depends strongly on the excitation wavelength. Most strikingly, a structured, long-lived fluorescence is observed in solution at room temperature after excitation into the S2 state, which is shifted hypsochromically by 30 nm compared to excitation into the S1 state. This very unusual behavior is investigated in detail with steady-state and time-resolved emission spectroscopy, ultrafast transient absorption spectroscopy, and quantum chemical calculations with both wave functions (CC2-level) and density-functional theory (DFT). 2PyA is found to emit simultaneously from two different intramolecular charge transfer states (mesomeric and twisted, MICT and TICT) which are populated most efficiently via the S1 state and a pyrene-like locally excited (LE) state. Rotational momentum derived from excess excitation energy is required to populate twisted LE configurations. Therefore, the LE state is most efficiently accessible via excitation to the S2. The stabilization of the different substates is related to two distinct reaction coordinates: the adenine-pyrene distance and the adenine-pyrene tilt angle, respectively.

Abstract
2'-O-(1-Pyrenylmethyl)uridine modified oligoribonucleotides provide highly sensitive pyrene fluorescent probes for detecting specific nucleotide mutation of RNA targets. To develop more stable and cost-effective oligonucleotide probes, we investigated the local microenvironmental effects of nearby nucleobases on pyrene fluorescence in duplexes of RNAs and 2'-O-(1-pyrenylmethyl)uridine modified oligonucleotides. By incorporation of deoxyribonucleotides, ribonucleotides, 2'-MeO-nucleotides and 2'-F-nucleotides at both sides of 2'-O-(1-pyrenylmethyl)uridine (U(p)) in oligodeoxynucleotide probes, we synthesized a series of pyrene modified oligonucleotide probes. Their pyrene fluorescence emission spectra indicated that only two proximal nucleotides have a substantial effect on the pyrene fluorescence properties of these oligonucleotide probes hybridized with target RNA with an order of fluorescence sensitivity of 2'-F-nucleotides > 2'-MeO-nucleotides > ribonucleotides ≫ deoxyribonucleotides. While based on circular dichroism spectra, overall helix conformations (either A- or B-form) of the duplexes have marginal effects on the sensitivity of the probes. Instead, the local substitution reflected the propensity of the nucleotide sugar ring to adopt North type conformation and, accordingly, shifted their helix geometry toward a more A-type like conformation in local microenvironments. Thus, higher enhancement of pyrene fluorescence emission favored local A-type helix structures and more polar and hydrophobic environments (F > MeO > OH at 2' substitution) of duplex minor grooves of probes with the target RNA. Further dynamic simulation revealed that local microenvironmental effect of 2'-F-nucleotides or ribonucleotides was enough for pyrene moiety to move out of nucleobases to the minor groove of duplexes; in addition, 2'-F-nucleotide had less effect on π-stack of pyrene-modified uridine with upstream and downstream nucleobases. The present oligonucleotide probes successfully distinguished target RNA from single-mutated RNA analyte during an in vitro assay of RNA synthesis.

Abstract
A series of novel nucleotide phosphoramidites were rationally designed and synthesized and were then site-specifically incorporated in DNA oligonucleotide probes with pyrene-modified phosphate. These oligodeoxynucleotide (ODN) probes almost have no inherent fluorescence emission with pyrene modification at 3' phosphate of corresponding nucleotides as a result of the photoinduced electron-transfer quenching effect of nucleobases (thymidine ∼ cytidine > guanosine ≫ adenosine). However, strong fluorescence emission was observed only with the perfectly matched duplex for the probes with pyrene modified at 3' phosphate of thymidine and cytidine. These rationally designed ODN probes successfully worked as "turn on" fluorescence oligonucleotide sensors for single-nucleotide polymorphism (SNP) and were used for detecting a single BRAF mutation site (V600E) of human melanoma.

Abstract
Pyrene-labeled 3-deaza-2'-deoxyadenosine comprising a non-π-conjugated linker (py3z)A (1) was synthesized and its photophysical properties were investigated. Oligodeoxynucleotide (ODN) probes containing (py3z)A (1) exhibited remarkable fluorescence quenching only when the opposite base of the complementary strand was the perfectly matched thymine. Such fluorescence quenching-based ODN probes exhibited excellent on-off switching properties, making them useful tools for single nucleotide polymorphism (SNP) genotyping and for the identification of target genes and structural studies of nucleic acids.

Abstract
The design and the synthesis of a PNA oligomer containing a pyrenyl residue in the backbone were performed. PNA sequence was chosen complementary to a "G rich" target sequence involved in G-quadruplex formation. The pyrenyl unit replaced a nucleobase in the middle of the PNA through covalent linkage to the backbone by a carboxymethyl unit. A systematic study on the binding properties of this probe towards DNA and RNA complementary strands was carried out by UV and fluorescence spectroscopy. UV melting curves indicated that the PNA probe binds more tightly to RNA rather than to DNA. Thermodynamic data obtained by Van't Hoff fitting of the melting curves indicated that, in the case of RNA, a more favorable interaction occurs between the pyrenyl unit and the RNA nucleobases, leading to a very favorable enthalpic contribution.The fluorescence analysis showed specific quenching of the pyrene emission associated to the formation of the full-match PNA-DNA or PNA-RNA duplexes. Again, this behavior was more evident in the case of RNA, consistently with the stronger interaction of the pyrenyl unit with the complementary strand. In order to study the sequence specificity of the pyrenyl-PNA probe (pyr-PNA), recognition experiments on mismatched DNA and RNA sequences were also performed.

Abstract
A molecular beacon (MB) is a hairpin-structured oligonucleotide probe containing a photoluminescent species (PLS) and a quencher at different ends of the strand. In a recognition and detection process, the hybridization of MBs with target DNA sequences restores the strong photoluminescence, which is quenched before hybridization. Making better MBs involves reducing the background photoluminescence and increasing the brightness of the PLS, which therefore involves the development of new PLS and quenchers, as well as innovative PLS-quencher systems. Heavy-metal complexes, nanocrystals, pyrene compounds, and other materials with excellent photophysical properties have been applied as PLS of MBs. Nanoparticles, nanowires, graphene, metal films, and many other media have also been introduced to quench photoluminescence. On the basis of their high specificity, selectivity, and sensitivity, MBs are developed as a general platform for sensing, producing, and carrying molecules other than oligonucleotides.

Abstract
Pyrene-functionalized oligonucleotides (PFOs) are increasingly explored as tools in fundamental research, diagnostics and nanotechnology. Their popularity is linked to the ability of pyrenes to function as polarity-sensitive and quenchable fluorophores, excimer-generating units, aromatic stacking moieties and nucleic acid duplex intercalators. These characteristics have enabled development of PFOs for detection of complementary DNA/RNA targets, discrimination of single nucleotide polymorphisms (SNPs), and generation of π-arrays on nucleic acid scaffolds. This critical review will highlight the physical properties and applications of PFOs that are likely to provide high degree of positional control of the chromophore in nucleic acid complexes. Particular emphasis will be placed on pyrene-functionalized Locked Nucleic Acids (LNAs) since these materials display interesting properties such as fluorescence quantum yields approaching unity and recognition of mixed-sequence double stranded DNA (144 references).

Abstract
A pyrene-labeled uridine (U(Py)) monomer for a pyrrolidinyl peptide nucleic acid with an alternating proline/2-aminocyclopentanecarboxylic acid backbone (acpcPNA) was synthesized and incorporated into the PNA. The U(Py) base in acpcPNA could specifically recognize the base A in its complementary DNA strand as determined by thermal denaturation (T(m)) experiments. The fluorescence of the U(Py)-containing single-stranded acpcPNA was very weak in aqueous buffer. In the presence of a complementary DNA target, the fluorescence was enhanced significantly (2.7-41.9 folds, depending on sequences). The fluorescence enhancement was specific to the pairing between U(Py) and dA, making the U(Py)-modified acpcPNA useful as a hybridization-responsive fluorescence probe for DNA-sequence determination.

Abstract
It is well known that nucleic acids play an essential role in living organisms because they store and transmit genetic information and use that information to direct the synthesis of proteins. However, less is known about the ability of nucleic acids to bind specific ligands and the application of oligonucleotides as molecular probes or biosensors. Oligonucleotide probes are single-stranded nucleic acid fragments that can be tailored to have high specificity and affinity for different targets including nucleic acids, proteins, small molecules, and ions. One can divide oligonucleotide-based probes into two main categories: hybridization probes that are based on the formation of complementary base-pairs, and aptamer probes that exploit selective recognition of nonnucleic acid analytes and may be compared with immunosensors. Design and construction of hybridization and aptamer probes are similar. Typically, oligonucleotide (DNA, RNA) with predefined base sequence and length is modified by covalent attachment of reporter groups (one or more fluorophores in fluorescence-based probes). The fluorescent labels act as transducers that transform biorecognition (hybridization, ligand binding) into a fluorescence signal. Fluorescent labels have several advantages, for example high sensitivity and multiple transduction approaches (fluorescence quenching or enhancement, fluorescence anisotropy, fluorescence lifetime, fluorescence resonance energy transfer (FRET), and excimer-monomer light switching). These multiple signaling options combined with the design flexibility of the recognition element (DNA, RNA, PNA, LNA) and various labeling strategies contribute to development of numerous selective and sensitive bioassays. This review covers fundamentals of the design and engineering of oligonucleotide probes, describes typical construction approaches, and discusses examples of probes used both in hybridization studies and in aptamer-based assays.

Abstract
Molecular beacon (MB) probes are dual-labeled hairpin-shaped oligodeoxyribonucleotides that are extensively used for real-time detection of specific RNA/DNA analytes. In the MB probe, the loop fragment is complementary to the analyte: therefore, a unique probe is required for the analysis of each new analyte sequence. The conjugation of an oligonucleotide with two dyes and subsequent purification procedures add to the cost of MB probes, thus reducing their application in multiplex formats. Here we demonstrate how one MB probe can be used for the analysis of an arbitrary nucleic acid. The approach takes advantage of two oligonucleotide adaptor strands, each of which contains a fragment complementary to the analyte and a fragment complementary to an MB probe. The presence of the analyte leads to association of MB probe and the two DNA strands in quadripartite complex. The MB probe fluorescently reports the formation of this complex. In this design, the MB does not bind the analyte directly; therefore, the MB sequence is independent of the analyte. In this study one universal MB probe was used to genotype three human polymorphic sites. This approach promises to reduce the cost of multiplex real-time assays and improve the accuracy of single-nucleotide polymorphism genotyping.
