Multiplexed DNA detection based on positional encoding/decoding with self-assembled DNA nanostructures.

ABSTRACT: Current multiplexed analysis methods suffer from either slow reaction kinetics (planar arrays) or complicated encoding/decoding procedures (suspension arrays). We report herein a multiplexed DNA detection strategy that addresses these issues, based on positional encoding/decoding with self-assembled DNA nanostructures. The strategy enables the acquisition of high-resolution, consistent, and quantitative assay results in a single round of a transmission electron microscopy imaging operation. Applications in polymerase chain reaction-free settings and assays of other structurally distinct targets can be anticipated through the implementation of the strategy with miniaturized femtoliter/attoliter dispensing technology and readily accessible DNA conjugate structures.

Self-assembled combinatorial encoding nanoarrays for multiplexed biosensing.

Project description:Multiplexed and sensitive detection of nucleic acids, proteins, or other molecules from a single solution and a small amount of sample is of great demand in biomarker profiling and disease diagnostics. Here we describe a new concept using combinatorial self-assembly of DNA nanotiles into micrometer-sized two-dimensional arrays that carry nucleic acid probes and barcoded fluorescent dyes to achieve multiplexed detection. We demonstrated the specificity and sensitivity of the arrays by detecting multiple DNA sequences and aptamer binding molecules. This DNA tile-array-based sensor platform can be constructed through DNA self-assembly. The attachment of different molecular probes can be achieved by simple DNA hybridization so bioconjugation is not necessary for the labeling. Accurate control of the interprobe distances and solution-based binding reactions ensures fast target binding kinetics.

Capturing intracellular oncogenic microRNAs with self-assembled DNA nanostructures for microRNA-based cancer therapy.

Project description:Aberrantly overexpressed oncogenic microRNAs (miRNAs, miRs) are excellent targets for therapeutic interventions. Nevertheless, thus far, little progress has been made in developing miRNA-based drugs and techniques for clinical applications, especially for overexpressed miRNAs. In this study, we demonstrate that self-assembled DNA nanostructures bearing multiple DNA sequences that are complementary to a target miRNA can effectively capture the overexpressed oncogenic miRNA and subsequently inhibit cancer cell proliferation. Specifically, a DNA nanotube structure that carries functional DNA segments (single-stranded, duplex and hairpin forms) was designed and synthesized to capture two well-known overexpressed miRNAs, miR-21 and miR-155. It was found that all three DNA nanotubes significantly reduced both miRNA levels and inhibited cancer cell growth. Moreover, the capture efficiency was highly concentration dependent and was associated with the structural design of the DNA nanotube. These results demonstrate that through careful design, programmable DNA nanostructures can hijack the natural cellular machinery and can serve as nucleic acid drugs themselves. The concept of using self-assembled DNA nanostructures to disrupt the intracellular machinery for therapeutic purposes opens a new paradigm for exploiting self-assembled DNA nanostructures for miRNA-based anticancer therapy.

Self-assembled bionanostructures: proteins following the lead of DNA nanostructures.

Project description:Natural polymers are able to self-assemble into versatile nanostructures based on the information encoded into their primary structure. The structural richness of biopolymer-based nanostructures depends on the information content of building blocks and the available biological machinery to assemble and decode polymers with a defined sequence. Natural polypeptides comprise 20 amino acids with very different properties in comparison to only 4 structurally similar nucleotides, building elements of nucleic acids. Nevertheless the ease of synthesizing polynucleotides with selected sequence and the ability to encode the nanostructural assembly based on the two specific nucleotide pairs underlay the development of techniques to self-assemble almost any selected three-dimensional nanostructure from polynucleotides. Despite more complex design rules, peptides were successfully used to assemble symmetric nanostructures, such as fibrils and spheres. While earlier designed protein-based nanostructures used linked natural oligomerizing domains, recent design of new oligomerizing interaction surfaces and introduction of the platform for topologically designed protein fold may enable polypeptide-based design to follow the track of DNA nanostructures. The advantages of protein-based nanostructures, such as the functional versatility and cost effective and sustainable production methods provide strong incentive for further development in this direction.

Self-assembled DNA nanostructures for distance-dependent multivalent ligand-protein binding.

Project description:An important goal of nanotechnology is to assemble multiple molecules while controlling the spacing between them. Of particular interest is the phenomenon of multivalency, which is characterized by simultaneous binding of multiple ligands on one biological entity to multiple receptors on another. Various approaches have been developed to engineer multivalency by linking multiple ligands together. However, the effects of well-controlled inter-ligand distances on multivalency are less well understood. Recent progress in self-assembling DNA nanostructures with spatial and sequence addressability has made deterministic positioning of different molecular species possible. Here we show that distance-dependent multivalent binding effects can be systematically investigated by incorporating multiple-affinity ligands into DNA nanostructures with precise nanometre spatial control. Using atomic force microscopy, we demonstrate direct visualization of high-affinity bivalent ligands being used as pincers to capture and display protein molecules on a nanoarray. These results illustrate the potential of using designer DNA nanoscaffolds to engineer more complex and interactive biomolecular networks.

Single-Step Organization of Plasmonic Gold Metamaterials with Self-Assembled DNA Nanostructures.

Project description: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.

Genetic encoding of DNA nanostructures and their self-assembly in living bacteria.

Project description:The field of DNA nanotechnology has harnessed the programmability of DNA base pairing to direct single-stranded DNAs (ssDNAs) to assemble into desired 3D structures. Here, we show the ability to express ssDNAs in Escherichia coli (32-205?nt), which can form structures in vivo or be purified for in vitro assembly. Each ssDNA is encoded by a gene that is transcribed into non-coding RNA containing a 3'-hairpin (HTBS). HTBS recruits HIV reverse transcriptase, which nucleates DNA synthesis and is aided in elongation by murine leukemia reverse transcriptase. Purified ssDNA that is produced in vivo is used to assemble large 1D wires (300?nm) and 2D sheets (5.8??m(2)) in vitro. Intracellular assembly is demonstrated using a four-ssDNA crossover nanostructure that recruits split YFP when properly assembled. Genetically encoding DNA nanostructures provides a route for their production as well as applications in living cells.

In situ Surface Charge Density Visualization of Self-assembled DNA Nanostructures after Ion Exchange.

Project description:The charge density of DNA is a key parameter in strand hybridization and for the interactions occurring between DNA and molecules in biological systems. Due to the intricate structure of DNA, visualization of the surface charge density of DNA nanostructures under physiological conditions was not previously possible. Here, we perform a simultaneous analysis of the topography and surface charge density of DNA nanostructures using atomic force microscopy and scanning ion conductance microscopy. The effect of in?situ ion exchange using various alkali metal ions is tested with respect to the adsorption of DNA origami onto mica, and a quantitative study of surface charge density reveals ion exchange phenomena in mica as a key parameter in DNA adsorption. This is important for structure-function studies of DNA nanostructures. The research provides an efficient approach to study surface charge density of DNA origami nanostructures and other biological molecules at a single molecule level.

Monolayer formed by l-Asp-based gemini surfactants self-assembled in 1D nanostructures.

Project description:Herein, studies on the surface activities of newly synthesized l-Asp-based gemini surfactants, both nonionic and anionic, are presented. Conductometry, tensiometry, and the Langmuir-Blodgett (LB) film technique were applied for this purpose. π-A isotherms were obtained with a Langmuir trough and Wilhelmy balance. The structures of the monolayers assembled at the air/water interface and those deposited as LB films were studied via Brewster angle microscopy (BAM) and atomic force microscopy (AFM). The 2D films formed by the anion-active compounds show a well-known pattern of a monolayer film, whereas the nonionogenic amphiphiles have been found to be 1D structures with nano-widths and micro-lengths that align with each other during the process of compression; this is the first study where the organization of 1D fibrils in 2D films during compression is reported. The scanning electron microscopy (SEM) study reveals that 1D nanostructure formation is an intrinsic tendency of these molecules as not only nonionogenic surfactants, but also the anion active representatives have been constructed in the solid state by fibrillary structures.

Chemically self-assembled antibody nanostructures as potential drug carriers.

Project description:Chemically self-assembled antibody nanorings (CSANs) displaying multiple copies of single-chain variable fragments can be prepared from dihydrofolate reductase (DHFR) fusion proteins and bis-methotrexate (bisMTX). We have designed and synthesized a bisMTX chemical dimerizer (bisMTX-NH(2)) that contains a third linker arm that can be conjugated to fluorophores, radiolabels, and drugs. Monovalent, divalent, and higher-order AntiCD3 CSANs were assembled with a fluorescein isothiocyanate (FITC)-labeled bis-methotrexate ligand (bisMTX-FITC) and found to undergo rapid internalization and trafficking by HPB-MLT, a CD3+ T-leukemia cell line, to the early and late endosome and lysosome. Because the fluorescence of bisMTX-FITC when incorporated into CSANs was found to be significantly greater than that of the free ligand, the stability of the endocytosed AntiCD3 CSANs could be monitored. The internalized CSANs were found to be stable for several hours, while treatment with the nontoxic DHFR inhibitor trimethoprim resulted in a rapid loss (>80%) of cellular fluorescence within minutes, consistent with efficient intracellular disassembly of the nanorings. Over longer time periods (24 h), cellular fluorescence decreased by 75-90%, regardless of whether cells had been treated with DMSO or trimethoprim. Although bisMTX is a potent inhibitor of DHFR, it was found to be nontoxic (GI(50) > 20 ?M) to HPB-MLT cells. In contrast, AntiCD3 CSANs prepared with bisMTX were found to be at least 13-fold more cytotoxic (GI(50) = 0.5-1.5 ?M) than bisMTX at 72 h. Consistent with our findings from CSAN stability studies, no increase in cytotoxicity was observed upon treatment with trimethoprim. Taken together, our results suggest that cell receptor targeting CSANs prepared with trifunctional bisMTX could be used as potential tissue selective drug carriers.

A templating approach for monodisperse self-assembled organic nanostructures.

Project description:The precise structural control is known for self-assembly into closed spherical structures (e.g., micelles), but similar control of open structures is much more challenging. Inspired by natural tobacco mosaic virus, we present the use of a rigid-rod template to control the size of a one-dimensional self-assembly. We believe that this strategy is novel for organic self-assembly and should provide a general approach to controlling size and dimension.
