Abstract
Quantifying intracellular microRNA (miRNA) is essential for diagnosis and prognosis of diseases because of its importance to the development and progression of complex diseases. The challenge is to develop methods that enable multiplex miRNAs detection in ultralow amounts and over broad concentration ranges. Inspired by the "tentacles" of an octopus, herein, we present a framework nucleic acid (FNA) capture for sensitive, rapid, and multiplexed imaging of miRNAs cancer biomarkers in living cells. The programmable FNA is designed using three DNA triangular prism (DTP) nanostructures carrying two pairs of metastable catalytic hairpin assembled (CHA) probes, AS1411 aptamer, and pendent biotinylated DNA strand in different vertexes and is further assembled via streptavidin to form the multivalent DTP (SA-DTP). The SA-DTP system acts as an octopus that captures the target cancer miRNAs quickly and delivers them preferentially among DTPs' "tentacles" in the SA-DTP system to produce strong, amplified fluorescence for detection. Precise multiplexed imaging of miRNA-155 and miRNA-21 cancer biomarkers' aberrant expression and dynamic change in different cells demonstrates the feasibility of both monitoring disease progression and evaluating therapeutic efficacy.

Abstract
Intraoperative image-guided surgery (IGS) has attracted extensive research interests in determination of tumor margins from surrounding normal tissues. Introduction of near infrared (NIR) fluorophores into IGS could significantly improve the in vivo imaging quality thus benefit IGS. Among the reported NIR fluorophores, rare-earth nanoparticles exhibit unparalleled advantages in disease theranostics by taking advantages such as large Stokes shift, sharp emission spectra, and high chemical/photochemical stability. The recent advances in elements doping and morphologies controlling endow the rare-earth nanoparticles with intriguing optical properties, including emission span to NIR-II region and long life-time photoluminescence. Particularly, NIR emissive rare earth nanoparticles hold advantages in reduction of light scattering, photon absorption and autofluorescence, largely improve the performance of nanoparticles in biological and pre-clinical applications. In this review, we systematically compared the benefits of RE nanoparticles with other NIR probes, and summarized the recent advances of NIR emissive RE nanoparticles in bioimaging, photodynamic therapy, drug delivery and NIR fluorescent IGS. The future challenges and promises of NIR emissive RE nanoparticles for IGS were also discussed.

Abstract
Receptor-ligand interactions (RLIs) that play pivotal roles in living organisms are often depicted with the classic keys-and-locks model. Nevertheless, RLIs on the cell surface are generally highly complex and nonlinear, partially due to the noncontinuous and dynamic distribution of receptors on extracellular membranes. Here, we develop a tetrahedral DNA framework (TDF)-programmed approach to topologically engineer RLIs on the cell membrane, which enables active recruitment-binding of clustered receptors for high-affinity capture of circulating tumor cells (CTCs). The four vertices of a TDF afford orthogonal anchoring of ligands with spatial organization, based on which we synthesized n-simplexes harboring 1-3 aptamers targeting epithelial cell adhesion molecule (EpCAM) that are overexpressed on the membrane of tumor cells. The 2-simplex with three aptamers not only shows increased binding affinity (∼19-fold) but prevents endocytosis by cells. By using 2-simplex as the capture probe, we demonstrate the high-efficiency CTC capture, which is challenged in real clinical breast cancer patient samples. This TDF-programmed platform thus provides a powerful means for studying RLIs in physiological settings and for cancer diagnosis.

Abstract
Single-base changes lead to important biological and biomedical implications; however, the discrimination of single-base changes from normal DNA always remains a grand challenge. Herein we developed a DNA recognition and amplification system based on artificial branched DNA, namely, target-triggered polymerization (TTP), to realize enzyme-free and fast discrimination of single-base changes. Branched DNA as monomers rapidly polymerized into DNA nanospheres only with the trigger of specific DNA. Our TTP system worked reliably over a wide range of conditions. Remarkably, our TTP system was capable of discriminating base-changing DNA from normal DNA, including distinguishing 1-4 nucleotide changes and positions of single base, which was attributed to the significant amplification of small differences in hybridization thermodynamics and kinetics. We further proposed a theoretical method for calculating the hybridization probability of nucleic acids, which performed highly consistent with experimental results.

Biosens Bioelectron 2019; 147:111788. [PMID: 31671380 DOI: 10.1016/j.bios.2019.111788] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 10/12/2019] [Accepted: 10/14/2019] [Indexed: 01/03/2023]
Abstract
The sensitive imaging of telomerase RNA (TR) in living cells is crucial for improved guidance in cancer clinical diagnosis because its expression level is closely related to malignant diseases. The efficient delivery of multiple nucleic acid probes to target cells is critical for nucleic acid-based methods to successfully image low-abundance TR in living cells. While novel nanomaterials enhance delivery efficiency, uncontrolled loading and slow intracellular release remain major challenges for multiple-probe delivery. Here, we designed a facile DNA/RNA nanoflower (NF) to perform the controlled loading of multiple probes and rapid intracellular release based on the "zipper lock-and-key" strategy. First, a long RNA generated by rolling circle transcription acts as both the "smart zipper lock" and the delivery carrier to alternately lock multiple functional DNAs through DNA-RNA base pairing, and the resulting RNA/DNA hybrids self-assemble into packed NFs. The functional DNAs include the fluorescence molecular beacon H1 for TR recognition, H2 for hybrid chain reaction (HCR) and DNA-cholesterol for size control. After NF internalization by the cells, the intracellular RNase H acts as the "key" to specifically open the DNA/RNA NFs by cleaving the RNA in the DNA/RNA hybrid, releasing high amounts of H1 and H2 in a confined space and thereby facilitating the HCR amplification analysis of cytoplasmic TR. With the addition of a DNA-nuclear localization peptide component in the same NF, nuclear TR can also be sensitively detected. Compared with the regular H1/H2 mixture, the DNA/RNA NFs produced a higher-contrast fluorescence signal. This indicated that the proposed strategy allowed the side arms of H1/H2 to be sealed into the RNA sequence-programmed "zipper lock" by controlled loading, avoiding mutual nonspecific H1/H2 hybridization. In addition, due to the fast kinetics of the RNase endonuclease reaction, the loaded H1/H2 was quickly released. Furthermore, the strategy was successfully used to assay the expression levels of TR in HeLa, HepG2 and HL-7702 cells, demonstrating that this approach holds the potential for the sensitive detection of low-abundance biomarkers in living cells.

Abstract
Platinum(II) complexes with an N-heterocyclic carbene and a cyclometalating phenyl ligand (C^C*) are excellent candidates as efficient blue triplet emitters for OLED applications. The electronic and photophysical properties of these complexes can be fine-tuned with the objective to increase the quantum yields and lower the phosphorescence decay times. We found that platinum complexes with an imidazopyrazine C^C* ligand and bulky acetylacetonates are sky-blue triplet emitters, characterised by an almost unitary quantum yield and short phosphorescence decay times.

Abstract
Nonenzymatic nucleic acid amplification techniques (e.g. the hybridization chain reaction, HCR) have shown promising potential for amplified detection of biomarkers.
Nonenzymatic nucleic acid amplification techniques (e.g. the hybridization chain reaction, HCR) have shown promising potential for amplified detection of biomarkers. However, the traditional HCR occurs through random diffusion of DNA hairpins, making the kinetics and efficiency quite low. By assembling DNA hairpins at the vertexes of tetrahedral DNA nanostructures (TDNs), the reaction kinetics of the HCR is greatly accelerated due to the synergetic contributions of multiple reaction orientations, increased collision probability and enhanced local concentrations. The proposed quadrivalent TDN (qTDN)-mediated hyperbranched HCR has a ∼70-fold faster reaction rate than the traditional HCR. The approximately 76% fluorescence resonance energy transfer (FRET) efficiency obtained is the highest in the reported DNA-based FRET sensing systems as far as we know. Moreover, qTDNs modified by hairpins can easily load drugs, freely traverse plasma membranes and be rapidly cross-linked via the target-triggered HCR in live cells. The reduced freedom of movement as a result of the large crosslinked structure might constrain the hyperbranched HCR in a confined environment, thus making it a promising candidate for in situ imaging and photodynamic therapy. Hence, we present a paradigm of perfect integration of DNA nanotechnology with nucleic acid amplification, thus paving a promising way to the improved performance of nucleic acid amplification techniques and their wider application.

Abstract
Self-assembled DNA nanostructures hold great promise as nanoscale templates for organizing nanoparticles (NPs) with near-atomistic resolution. However, large-scale organization of NPs with high yield is highly desirable for nanoelectronics and nanophotonic applications. Here, we design five-strand DNA tiles that can readily self-assemble into well-organized micrometer-scale DNA nanostructures. By organizing gold nanoparticles (AuNPs) on these self-assembled DNA nanostructures, we realize the fabrication of one- and two-dimensional Au nanostructures in single steps. We further demonstrate the one-pot synthesis of Au metamaterials for highly amplified surface-enhanced Raman Scattering (SERS). This single-step and high-yield strategy thus holds great potential for fabricating plasmonic metamaterials.

Abstract
Spherical nucleic acids (SNAs) play critical roles in many fields, such as molecular diagnostics, disease therapeutics, and materials application. Due to the important role of DNA density on the properties of SNAs, the controlled synthesis of monodisperse SNAs with precise DNA density is an important approach for the structure-function relationship study and finite functions regulation of SNAs. In particular, the construction of monodisperse SNAs in a valency-tunable and site-specific manner is highly important; however, it is still challenging. Herein, on the basis of the high controllability, nanometer precision, and addressable modification ability of framework nucleic acid (FNA), we develop the concept of valency-controlled framework nucleic acid core-based molecular spherical nucleic acids (FNA-mSNAs) with tunable biosensing performances. The FNA-mSNAs consist of a valency-tunable FNA-based DNA nanocube as the core and a controlled, precise number of DNA strands per core. By simply alternating the binding site number for shell DNA strands on the DNA nanocube, homogeneous FNA-mSNAs with different valencies were easily designed, which enabled the molecular level study of the effect of valency on their properties, such as nuclease stability and cellular uptake. Furthermore, taking advantage of the addressable modification ability of FNA, the first heterogeneous molecular SNAs with tunable valency were demonstrated. Importantly, the valency of heterogeneous FNA-mSNAs was able to tune their biosensing performance, such as response dynamics, detection sensitivity, and response range. With these remarkable features, FNA-mSNAs provide new research methods for the development of functional SNAs at the molecular level for a wide range of biological applications.

Abstract
Herein, an efficient target-activated enzyme cascade electrocatalysis with low background signal was employed to establish electrochemical biosensor for ultrasensitive detection of thrombin via regulating electrocatalytic efficiency between target-induced hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme (HRP-mimicking DNAzyme) and glucose oxidase (GOx). Impressively, only when the target thrombin was introduced, the HRP-mimicking DNAzyme acting simultaneously as electrochemical signal probe would be formed to activate high-efficiency enzyme cascade electrocatalysis for reducing background signal significantly, which could overcome the defect of inevitable high background signal during the detection of target in the traditional cascade electrocatalysis of two existing bioenzymes. In addition, the detection sensitivity could be further improved by regulating the side length of rigid DNA tetrahedron (TDN) scaffold anchored HRP-mimicking DNAzyme and GOx at adjacent vertices for high enzyme cascade electrocatalytic efficiency. Consequently, the proposed biosensor demonstrated a low detection limit down to 0.3 fM for target thrombin, which provided a promising method for ultrasensitive monitoring of biomolecules in sensing analysis and disease diagnosis.

Abstract
Advances in biomimetic microelectronics offer a range of patterned assemblies of proteins and cells for in vitro metabolic engineering where coordinated biochemical pathways allow cell metabolism to be characterized and potentially controlled on a chip. To achieve these goals, developing new methods for interfacing biological systems to microelectronic devices has been in urgent demand. Here, we report the assembly of a DNA origami-templated enzymatic cascade (glucose oxidase and horseradish peroxidase) on gold electrodes, where a monolayer of DNA origami is anchored on gold electrodes via Au-S chemistry, to create programmable, electrochemically driven biomimetic device containing both biochemical and electronic components. Upon the posing of a specific electrical potential, substrates/products flow through the enzyme pair and the end product transfers electrons to the electrode. The steady state flux of the distance-dependent enzymatic cascade reactions is translated into a steady state current signal that records the overall enzyme activity. This biological system can be finely tuned by varying the distance between the enzyme pair, which opens new routes to interface microelectronic devices to biological functions.

Abstract
A single-step electrocatalytic biosensor with dual-affinity regulation enables a tunable dynamic range and tunable single nucleotide resolution for nucleic acid detection.
The rational modulation of receptor affinity through distal-site mutation and allosteric control is valuable in biosensor designing to tune the useful dynamic range. Our ability to programmatically engineer dual-affinity regulation into diverse affinities of target binding and activities of hybridization chain reaction, however, remains limited. By programmable engineering of the switching equilibria of the recognition hairpin using distal-site mutation inhibition and allosteric activation, we obtained a set of receptors varying significantly in affinities of target binding and activities of the hybridization chain reaction. For the first time, we developed an electrocatalytic biosensor for nucleic acid detection with a tunable dynamic range based on a conformational switch triggered bidirectional hybridization chain reaction and blocker assisted multivalent binding. This designable biosensor thus enables single-step incubation, diverse affinities of target binding, diverse efficiencies of signal amplification and diverse single nucleotide discrimination for quantitative analyses of nucleic acids of various lengths in serum, which holds great potential as a compelling platform suitable for liquid biopsy.

Abstract
DNA nanotechnology can construct various nanostructures with diverse functionalities. However, conformation fluctuations due to the structural flexibility of duplex DNA compromise the efficiency to realize the functionality and reactivity of DNA nanostructures. To understand and control the structural deviation from the design represents a major challenge as well as an opportunity for DNA nanotechnology. In the present work, two series of one-dimensional assemblies of DNA tetrahedrons (DTHs) were fabricated and applied to demonstrate the manipulations of conformation dynamics of a one-dimensional DTH assembly by simple variation on linkage styles at single-molecule resolution. A stepwise strategy allows both nanoassembly with a high fidelity in the number and sequence of DTH units to be assembled with a minimum number of linkage sequences. The characterization for these nanostructures with atomic force microscope (AFM) and a solid-state nanopore technique indicates the difference in conformation dynamics and bending stiffness between two analogous nanoassemblies both in the immobilized state on the surface and free state in solution. This work showed the power of fine-tuning the dynamic conformation of the nanostructures and could see the applications in single-molecule biosensing and functionalization of DNA nanostructures.

Abstract
Here, we explore the extended utility of two important functional biomolecules, DNA and protein, by hybridizing them through avidin-biotin conjugation. We report a simple yet scalable technique of successive magnetic separations to synthesize traptavidin-DNA conjugates with four distinct DNA binding sites that can be used as a supramolecular building block for programmable assembly of nanostructures. Using this nanoassembly platform, we fabricate several different plasmonic nanostructures with various metallic as well as semiconductor nanoparticles in predetermined ways. We also use the platform to construct dendrimer nanostructures using valency-controlled traptavidin-DNA conjugates in a programmable manner. These results suggest that our protein-DNA supramolecular building blocks would make a significant contribution to the assembly of multicomponent and complex nanostructures for numerous contemporary and future applications from molecular imaging to drug delivery.

Abstract
In nature, the formation of spider silk fibers begins with dimerizing the pH-sensitive N-terminal domains of silk proteins (spidroins) upon lowering pH, and provides a natural masterpiece for programmable assembly. Inspired by the similarity of pH-dependent dimerization behaviors, introduced here is an i-motif-guided model to mimic the initial step of spidroin assembly at the subcellular level. A framework nucleic acid (FNA) nanoplatform is designed using two tetrahedral DNA nanostructures (TDNs) with different branched vertexes carrying a bimolecular i-motif and a split ATP aptamer. Once TDNs enter acidic lysosomes within living cells, they assemble into a heterodimeric architecture, thereby enabling the formation of a larger-size framework and meanwhile subcellular imaging in response to endogenous ATP, which can be dynamically manipulated by adjusting intracellular pH and ATP levels with external drug stimuli.

Abstract
DNA aptamers are important tools for molecular recognition, particularly for a new generation of tools for biomedicine based on nucleic acid nanostructures. Here, we investigated the relative abilities of different shapes and sizes of DNA polyhedra to display an aptamer which binds to the malaria biomarker Plasmodium falciparum lactate dehydrogenase (PfLDH). The aptamer was shown to perform an Aptamer-Tethered Enzyme Capture (APTEC) assay with the hypothesis that the display of the aptamer above the surface through the use of a polyhedron may lead to better sensitivity than use of the aptamer alone. We compared different numbers of points of contact, different shapes, including tetrahedron, square, and pentagon-based pyramids, as well as prisms. We also investigated the optimal height of display of the structure. Our results demonstrated that the display of an aptamer on an optimized nanostructure improved sensitivity up to 6-fold relative to the aptamer alone in the APTEC assay. Other important factors included multiple basal points of contact with the surface, a tetrahedron proved superior to the more complex shaped structures, and height above the surface only made minor differences to efficacy. The display of an aptamer on a nanostructure may be beneficial for higher sensitivity aptamer-mediated malaria diagnosis. Aptamer displays using DNA nanostructure polyhedron supports could be a useful approach in a variety of applications.
