Abstract
The metal plasmonic nanostructure has the optical property of plasmon resonance, which holds great potential for development in nanophotonics, bioelectronics, and molecular detection. However, developing a general and straightforward method to prepare metal plasmonic nanostructures with a controllable size and morphology still poses a challenge. Herein, we proposed a synthesis strategy that utilized a customizable self-assembly template for shape-directed growth of metal structures. We employed gold nanoparticles (AuNPs) as connectors and DNA nanotubes as branches, customizing gold nanoparticle-DNA origami composite nanostructures with different branches by adjusting the assembly ratio between the connectors and branches. Subsequently, various morphologies of plasmonic metal nanostructures were created using this template shape guided strategy, which exhibited enhancement of surface-enhanced Raman scattering (SERS) signals. This strategy provides a new approach for synthesizing metallic nanostructures with multiple morphologies and opens up another possibility for the development of customizable metallic plasmonic structures with broader applications.

Abstract
We report on studies that demonstrate how the chemical composition of the surface of copper nanoparticles (CuNPs) - in terms of percentage copper(I/II) oxides - can be varied by the presence of N-donor ligands during their formation via laser ablation. Changing the chemical composition thus allows systematic tuning of the surface plasmon resonance (SPR) transition. The trialed ligands include pyridines, tetrazoles, and alkylated tetrazoles. CuNPs formed in the presence of pyridines, and alkylated tetrazoles exhibit a SPR transition only slightly blue shifted with respect to CuNPs formed in the absence of any ligand. On the other hand, the presence of tetrazoles results in CuNPs characterized by a significant blue shift of the order of 50-70 nm. By comparing these data also with the SPR of CuNPs formed in the presence of carboxylic acids and hydrazine, this work demonstrates that the blue shift in the SPR is due to tetrazolate anions providing a reducing environment to the nascent CuNPs, thus preventing the formation of copper(II) oxides. This conclusion is further supported by the fact that both AFM and TEM data indicate only small variations in the size of the nanoparticles, which is not enough to justify a 50-70 nm blue-shift of the SPR transition. High-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) studies further confirm the absence of Cu(II)-containing CuNPs when prepared in the presence of tetrazolate anions.

Fishing unfunctionalized SERS tags with DNA hydrogel network generated by ligation-rolling circle amplification for simple and ultrasensitive detection of kanamycin.

[PMID: 35325717 DOI: 10.1016/j.bios.2022.114187] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 03/09/2022] [Accepted: 03/11/2022] [Indexed: 12/14/2022]
Abstract
Simple assay format-based SERS methods for sensitive target substance analysis is of great significance for the development of on-site monitoring biosensors. Herein, taking the typical antibacterial kanamycin (KANA) as a subject, a simple, highly sensitive and specific SERS aptasensor was developed by manipulating DNA hydrogel network to fish plasmonic core-shell nanoparticles. A competitive binding mode of aptamer, ligation-rolling circle amplification (L-RCA), gap-containing Au@Au nanoparticles (GCNPs) with embedded Raman reporters were integrated into the sensor. In the presence of KANA, the double stranded DNA (dsDNA) structure of the aptamer was disrupted, and the released primers were used to construct two kinds of circularized padlock probes (CPPs) which were partially complementary. DNA hydrogel network was formed through the intertwining and self-assembly of two RCA-generated single stranded DNA (ssDNA) chains, during which GCNPs and magnetic beads (MBs) were entangled and incorporated. Finally, KANA quantification was successfully achieved through the quantification of the DNA hydrogel. Overall, this novel SERS aptasensor realized a simple and ultrasensitive quantification of KANA down to 2.3 fM, plus excellent selectivity, and precision even for real food samples. In view of innovative fusion across L-RCA-based DNA hydrogel and SERS technique, the proposed method has promising potential for application in on-site detection and quantification of trace food contaminants.

Abstract
Quantitative, label-free detection of neurotransmitters is of vital importance to the diagnosis and treatment of neurologic diseases. The surface-enhanced Raman scattering (SERS) effect has great application prospects in the field of biosensing and bioimaging because of its unique nondestructive testing and its capability of being used in molecular fingerprint identification. However, the quantitative SERS analysis of neurotransmitters is still a great challenge because of the poor reproducibility of the SERS-active sites, as well as the small Raman cross-section and low physiological concentration of neurotransmitter molecules. Here, we report the development of a stellate gold nanostructure with a 1 nm interior gap for the quantitative detection of neurotransmitters. The internal reference embedded into the hollow gap of the stellate gold nanoparticle allows the calibration of the signal of analytes absorbed on the surface, which improves the R-squared value of the linear fitting curve from 0.56 to 0.97 for quantitative dopamine detection. Our developed self-referenced SERS substrate holds great potential for label-free, quantitative SERS-based biosensing.

Abstract
Sensitive and simultaneous detection of multiple cancer-related biomarkers in serum is essential for diagnosis, therapy, prognosis, and staging of cancer. Herein, we proposed a magnetically assisted sandwich-type surface-enhanced Raman scattering (SERS)-based biosensor for ultrasensitive and multiplex detection of three hepatocellular carcinoma-related microRNA (miRNA) biomarkers. The biosensor consists of an SERS tag (probe DNA-conjugated DNA-engineered fractal gold nanoparticles, F-AuNPs) and a magnetic capture substrate (capture DNA-conjugated Ag-coated magnetic nanoparticles, AgMNPs). The proposed strategy achieved simultaneous and sensitive detection of three miRNAs (miRNA-122, miRNA-223, and miRNA-21), and the limits of detection of the three miRNAs in human serum are 349 aM for miRNA-122, 374 aM for miRNA-223, and 311 aM for miRNA-21. High selectivity and accuracy of the SERS biosensor were proved by practical analysis in human serum. Moreover, the biosensor exhibited good practicability in multiplex detection of three miRNAs in 92 clinical sera from AFP-negative patients, patients before and after hepatectomy, recurred and relapse-free patients after hepatectomy, and hepatocellular carcinoma patients at distinct Barcelona clinic liver cancer stages. The experiment results demonstrate that our SERS-based assay is a promising candidate in clinical application and exhibited potential for the prediction, diagnosis, monitoring, and staging of cancers.

Abstract
Infectious Escherichia coli O157:H7 threatens the health of millions people each year. Thus, it is important to establish a simple and sensitive method for bacterial detection and eradication. Herein, a DNA-programming strategy is explored to synthesize anisotropic dumbbell-like Au-Pt nanoparticles with excellent catalytic and anti-bacterial activities, which were applied in the simultaneous detection and eradication of pathogenic bacteria. The DNA sequence-dependent growth of bimetallic nanoparticles is firstly studied and polyT20 has the tendency to form dumbbell-like Au-Pt bimetallic structures based on gold nanorods seeds. PolyA20 and polyC20 can also form similar structures but only at much lower DNA concentrations, which can be explained by their much higher affinity to the metal surfaces than T20. The as-prepared nanoparticles exhibit high nanozyme catalytic activity resulting from the synergistic effect of Au and Pt. Under light irradiation, the Au-Pt nanoparticles show high photothermal conversion efficiency and enhanced catalytic activity, which can be applied for the eradication and detection of E. coli O157:H7 with a robust efficacy (95%) in 5 min and provides excellent linear detection (10-107 CFU/mL), with a detection limit of 2 CFU/mL. This study offered new insights into DNA-directed synthesis of nanomaterials with excellent biosensing and antibiotic applications.

Abstract
With the advent of nanofabrication techniques, plasmonic nanoparticles (PNPs) have been widely applied in various research fields ranging from photocatalysis to chemical and bio-sensing. PNPs efficiently convert chemical or physical stimuli in their local environment into optical signals. PNPs also have excellent properties, including good biocompatibility, large surfaces for the attachment of biomolecules, tunable optical properties, strong and stable scattering light, and good conductivity. Thus, single optical biosensors with plasmonic properties enable a broad range of uses of optical imaging techniques in biological sensing and imaging with high spatial and temporal resolution. This work provides a comprehensive overview on the optical properties of single PNPs, the description of five types of commonly used optical imaging techniques, including surface plasmon resonance (SPR) microscopy, surface-enhanced Raman scattering (SERS) technique, differential interference contrast (DIC) microscopy, total internal reflection scattering (TIRS) microscopy, and dark-field microscopy (DFM) technique, with an emphasis on their single plasmonic nanoprobes and mechanisms for applications in biological imaging and sensing, as well as the challenges and future trends of these fields.

Abstract
Citrate-capped gold nanoparticles (AuNPs) are highly important for sensing, drug delivery, and materials design. Many of their reactions take place in various buffers such as phosphate and Good's buffers. The effect of buffer on the surface properties of AuNPs is critical, yet this topic has not been systematically explored. Herein, we used halides such as fluoride, chloride, and bromide as probes to measure the relative adsorption strength of six common buffers. Among them, HEPES had the highest adsorption affinity, while MES, citrate and phosphate were weakly adsorbed with an overall ranking of HEPES > PIPES > MOPS > MES > citrate, phosphate. The adsorption strength was reflected from the inhibited adsorption of DNA and from the displacement of pre-adsorbed DNA. This conclusion is also supported by surface enhanced Raman spectroscopy. Furthermore, some buffer molecules did not get adsorbed instantaneously, and the MOPS buffer took up to 1 h to reach equilibrium. Finally, a classic label-free AuNP-based colorimetric sensor was tested. Its sensitivity increased by 15.7-fold when performed in a MES buffer compared to a HEPES buffer. This study has articulated the importance of buffer for AuNP-based studies and how it can improve sensors and yield more reproducible experimental systems. Aside from maintaining pH, Good's buffers can be adsorbed on gold nanoparticles with different affinities, affecting the stability and its fluorescent and colorimetric sensing performance.![]()

Abstract
Nobel metal nanoparticles with tunable morphologies are highly desirable due to their unique electronic, magnetic, optical, and/or catalytic features. Here we report the use of multilayered graphdyine (GD) as a substrate for the reductant-free, room-temperature synthesis of single-crystal Au nanostructures with tunable morphology. We find that the GD template rich in sp-carbon atoms possesses high affinity with Au atoms on the {111} facets, and that the intrinsic reductivity of GD facilitates the rapid growth of Au nanoplates. The introduction of single-stranded DNA strands further results in the synthesis of Au nanostructures with decreased anisotropy, i.e., polygons and flower-like nanoparticles. The DNA-guided tunable Au growth arises from the strong adsorption of DNA on the GD template that alters the uniformity of the interface, which provides a direct route to synthesize Au nanostructures with tailorable morphology and photonic properties.

Abstract
The near-field effects in the vicinity of metallic nanoparticle surfaces, as induced by electromagnetic radiation with specific wavelength, give rise to a variety of novel optical properties and attractive applications because of surface plasmons, which are the coherent oscillations of conduction electrons on a metal surface. The interdisciplinary field of plasmonics has witnessed vigorous growth, promoting research on the modulation of plasmon resonance by constructing advanced plasmonic nanoarchitectures with controllable size, morphology, or interparticle coupling. Among diversified tools, deoxyribonucleic nucleic acid (DNA) possesses prominent superiority as a result of its designability, programmability, addressability, and ease of nanomaterial modification. In this review, we focus on the methods and optical applications of plasmon resonance modulation accomplished by DNA nanotechnology. Recent developments in the construction of DNA-mediated plasmonic nanoarchitecture and key ongoing research directions utilizing unique optical features are highlighted. Obstacles and challenges in this field are pointed out, followed by preliminary suggestions on some areas of opportunity that deserve attention.

Abstract
Gap-enhanced Raman tags (GERTs) are emerging probes of surface-enhanced Raman scattering (SERS) spectroscopy that have found promising analytical, bioimaging, and theranostic applications. Because of their internal location, Raman reporter molecules are protected from unwanted external environments and particle aggregation and demonstrate superior SERS responses owing to the strongly enhanced electromagnetic fields in the gaps between metal core-shell structures. In this review, we discuss recent progress in the synthesis, simulation, and experimental studies of the optical properties and biomedical applications of novel spherically symmetrical and anisotropic GERTs fabricated with common plasmonic metals—gold (Au) and silver (Ag). Our discussion is focused on the design and synthetic strategies that ensure the optimal parameters and highest enhancement factors of GERTs for sensing and theranostics. In particular, we consider various core-shell structures with build-in nanogaps to explain why they would benefit the plasmonic GERTs as a superior SERS tag and how this would help future research in clinical analytics and therapeutics.

Abstract
Core-shell plasmonic metal nanoparticles with interior nanogaps are superior nanostructures owing to their large signal enhancement for Surface enhanced Raman spectroscopy (SERS). Herein, we incorporated Terminal deoxynucleotidyl transferase (TdT)-catalyzed DNA in the preparation of core-shell nanostructures for the detection of Escherichia coli O157:H7 (E. coli O157:H7) cells. The elongated products-homo-nucleotides-composed of long single DNA strands (hn-D) are used not only to induce tunable-size nanogaps but also as Raman reporters with consistent and uniform signal enhancement. Using this synthetic process of hn-D-embedded core-shell nanoparticles (hn-DENPs), we found that the length of hn-D strands affects the size of the nanogap. In addition, performances of the specific Raman imaging of E. coli O157:H7, high detection sensitivity of 2 CFU/mL, and the recovery of 98.1%-105.2% measured in the real food samples, make hn-DENP a biosensor that will be widely used in biological detection.

Abstract
Attaching thiolated DNA to gold nanoparticles (AuNPs) is a highly important and useful reaction for many applications. Various methods such as adding salts, acids, polymers, and surfactants have been developed to facilitate the reaction. Recently, it was reported that a very high DNA density can be achieved simply by freezing AuNPs with the DNA without any other reagents. DNA oligonucleotides are also known to stretch and align upon freezing. In this work, a set of experiments were performed with a fluorophore and thiol dual-labeled DNA, and the DNA loading density and colloidal stability of AuNPs were measured. The initial salt concentration was unimportant, and even 0.1 mM Na+ allowed around 100 DNA attached to each 13 nm AuNPs. On the other hand, a high DNA concentration of 3 μM was needed to achieve the high DNA density and good colloidal stability of AuNPs. When the thiolated DNA was forced in stable secondary structures, the attachment was low, and preadsorbed DNA also inhibited the DNA attachment by the freezing method. Overall, nonstructured thiolated DNA strands need to align by freezing and quickly attached through the ends of the DNA. This work illustrates practical experiment design conditions and offers fundamental surface science insights for the DNA attachment by freezing.

Abstract
Most proteins perform functions in intracellular milieu. The crowding, compartmentalized cytosol environment affects the protein structure, folding, conformational stability, substrate diffusion, and substrate-enzyme binding. Moreover, enzymes are available at single or very low copy numbers in a cell, and thus the conformation fluctuations of a single enzyme in a crowding environment could also greatly influence its kinetics. However, the crowding effect is poorly understood in the kinetical aspect of enzymatic reactions. In the present study, individual horseradish peroxidase (HRP) is encapsulated in a liposome containing crowding reagents as mimics of viscous cytosol. The confined crowding environment possesses a profound influence on both the catalytic activity and the product inhibition of enzymes. By analyzing the correlation between product generation and product inhibition, we find that the allosteric noncompetitive inhibition of HRP is alleviated in the crowded and confined milieu. Small-angle X-ray scattering experiments provide straightforward proofs of structural changes of enzymes in crowding environments, which are responsible for the reduced enzyme activity and increased enzyme-substrate affinity. We expect that this work may deepen the understanding of correlations between enzymatic conformations and activity performance in real cellular environments.

Abstract
By incorporating hemin into G-quadruplex (G4) during cation-templated self-assembly between guanosine and KB(OH)4, we have constructed an artificial enzyme hydrogel (AEH)-based system for the highly sensitive and selective detection of Pb2+. The sensing strategy is based on a Pb2+-induced decrease in AEH activity. Because of the higher efficiency of Pb2+ for stabilizing G4 compared with K+, the Pb2+ ions substitute K+ and trigger hemin release from G4, thus giving rise to a conformational interconversion accompanied by the loss of enzyme activity. The Pb2+-induced catalytic interconversion endows the AEH-based system with high sensitivity and selectivity for detecting Pb2+. As a result, the AEH-based system shows an excellent response for Pb2+ in the range from 1 pM to 50 nM with a limit of detection of ∼0.32 pM, which is much lower than that of the previously reported G4-DNAzyme. We also demonstrate that this AEH-based system exhibits high selectivity toward Pb2+ over other metal ions. Furthermore, two two-input INHIBIT logic gates have been constructed via switching of the catalytic interconversion induced by K+ and Pb2+ or K+ and pH. Given its versatility, this AEH-based system provides a novel platform for sensing and biomolecular computation.

Abstract
Calcium phosphate (CaP) has long been used for DNA delivery, although its fundamental interaction with DNA, especially with single-stranded DNA oligonucleotides, remains to be fully understood. Using fluorescently labeled oligonucleotides, we herein studied DNA adsorption isotherm and the effect of DNA length and sequence. Longer DNAs are adsorbed more strongly, and at neutral pH, poly-C DNAs are adsorbed more than the other three DNA homopolymers. However, at near pH 11, the pH of CaP synthesis, T30 DNA is adsorbed more strongly than C30 or A30. This can explain why T30 and G30 can fully inhibit the growth of CaP, while A30 and C30 only retarded its growth kinetics. DNA adsorption also reduces aggregation of CaP. DNA desorption experiments were carried out using concentrated urea, thymidine, or inorganic phosphate as competitors, and desorption was observed only in the presence of phosphate, suggesting that DNA uses its phosphate backbone to interact with the CaP surface. Desorption was also promoted by raising the NaCl concentration suggesting the electrostatic nature of interaction. Finally, ten different metal phosphate materials were synthesized by co-precipitating each metal ion (Ce3+, Fe3+, Ca2+, Ni2+, Zn2+, Mn2+, Ba2+, Cu2+, Sr2+, Co2+), and DNA adsorption by these phosphate precipitants was found to be related to their surface charge and metal chemistry. This work has revealed fundamental surface science of DNA adsorption by CaP and other metal phosphate salts, and this knowledge might be useful for gene delivery, biomineralization, and DNA-directed assembly of metal phosphate materials.

Abstract
Triplex nucleic acids have recently attracted interest as part of the rich "toolbox" of structures used to develop DNA-based nanostructures and materials. This Review addresses the use of DNA triplexes to assemble sensing platforms and molecular switches. Furthermore, the pH-induced, switchable assembly and dissociation of triplex-DNA-bridged nanostructures are presented. Specifically, the aggregation/deaggregation of nanoparticles, the reversible oligomerization of origami tiles and DNA circles, and the use of triplex DNA structures as functional units for the assembly of pH-responsive systems and materials are described. Examples include semiconductor-loaded DNA-stabilized microcapsules, DNA-functionalized dye-loaded metal-organic frameworks (MOFs), and the pH-induced release of the loads. Furthermore, the design of stimuli-responsive DNA-based hydrogels undergoing reversible pH-induced hydrogel-to-solution transitions using triplex nucleic acids is introduced, and the use of triplex DNA to assemble shape-memory hydrogels is discussed. An outlook for possible future applications of triplex nucleic acids is also provided.

Abstract
The first appeal of clinical assay is always accurate and rapid. For alkaline phosphatase (ALP) monitoring in medical treatment, a rapid, reliable surface-enhanced Raman scattering (SERS) test kit is designed based on a "hot spots" amplification strategy. Consisting of alkyne-tagged Au nanoparticles (NPs), Ag+, and enzyme substrate, the packaged test kit can achieve one-step clinical assay of ALP in human serum within several minutes, while the operation is simple as it directly inputs the sample into the test kit. Here, Ag+ ions are adsorbed onto the surface of Au core due to electrostatic interaction between Ag+ and the negatively charged donor surface, then enzymatic biocatalysis of ALP triggers the reduction of Ag+ and subsequently silver growth occurs on every Au core surface in a controllable manner, forming "hot spots" between the Au core and Ag shell, in which the SERS signal of alkyne Raman reporters would be highly amplified. Meanwhile, ALP mediates a redox reaction of Ag+ as well as the dynamic silver coating process so the increase of SERS intensity is well-controlled and can be recognized with increasing amounts of the targets. Instead of conventional NP aggregation, this leads to a more reproducible result. In particular, the distinct Raman emission from our self-synthesized alkyne reporter is narrow and stable with zero background in the Raman silent region, suffering no optical fluctuation from biosystem inputs and the detection results are therefore reliable with a limit of detection of 0.01 U/L (2.3 pg/mL). Along with ultrahigh stability, this SERS test kit therefore is an important point-of-care candidate for a reliable, efficacious, and highly sensitive detection method for ALP, which potentially decreases the need for time-consuming clinical trials.

Abstract
Herein, a versatile and sensitive colorimetric sensor for Hg2+ based on aptamer-target specific binding and target-mediated growth of AuNPs is reported. The 15 T bases are first designed to detect Hg2+ through T-Hg2+ -T coordination. Aptamer-target binding results in the desorption of the aptamer from AuNP surface, the remaining aptamers adsorbed on AuNP surface trigger the growth of AuNPs with morphologically varied nanostructures, and then different colored solutions are formed. On this occasion, the limit of detection (LOD) of 9.6 × 10-9 m is obtained. The other two aptamer strands (25- and 59-mer) are designed by increasing A bases on either side and both sides of 15 T, respectively. The interaction of the binding domain and Hg2+ makes desorption of 15 T from AuNP surface, whereas excess bases not committed to the binding domain still adsorbed on AuNP surface. These excess bases control the growth of AuNPs, and enhance the sensitivity. The LODs are 4.05 and 3 × 10-9 m for 25- and 59-mer aptamers, respectively. In addition, the 59-mer aptamer system is applied to identify Hg2+ in real river samples, the LOD of 6.2 × 10-9 m is obtained.

Abstract
DNA-functionalized gold nanoparticles (AuNPs) have been extensively used in sensing, drug delivery, and materials science. A key step is to attach DNA to AuNPs, forming a stable and functional conjugate. Although the traditional salt-aging method takes a full day or longer, a recent low-pH method allows DNA conjugation in a few minutes. The effect of low pH was attributed to the protonation of adenine (A) and cytosine (C), resulting in an overall lower negative charge density on DNA. In this work, the effect of DNA conformation at low pH is studied. Using circular dichroism (CD) spectroscopy, the parallel poly-A duplex (A-motif) is detected when a poly-A segment is linked to a random DNA, a design typically used for DNA conjugation. A DNA staining dye, thiazole orange, is identified for detecting such A-motifs. The A-motif structure is ideal for DNA conjugation because it exposes the thiol group to directly react with the gold surface while minimizing nonspecific DNA base adsorption. For nonthiolated DNA, the optimal procedure is to incubate DNA and AuNPs followed by lowering the pH. The i-motif formed by poly-C DNA at low pH is less favorable to the conjugation reaction because of its unique way of folding. The stability of poly-A and poly-G DNA at low pH is examined. An excellent stability of poly-A DNA is confirmed, but poly-G has lower stability. This study provides new fundamental insights into a practically useful technique of conjugating DNA to AuNPs.

Abstract
Plasmonic nanostructures are widely studied and used because of their useful size, shape, composition and assembled structure-based plasmonic properties. It is, however, highly challenging to precisely design, reproducibly synthesize and reliably utilize plasmonic nanostructures with enhanced optical properties. Here, we devise a facile synthetic method to generate Au surface roughness-controlled nanobridged nanogap particles (Au-RNNPs) with ultrasmall (≈1 nm) interior gap and tunable surface roughness in a highly controllable manner. Importantly, we found that particle surface roughness can be associated with and enhance the electromagnetic field inside the interior gap, and stronger nanogap-enhanced Raman scattering (NERS) signals can be generated from particles by increasing particle surface roughness. The finite-element method-based calculation results support and are matched well with the experimental results and suggest one needs to consider particle shape, nanogap and nanobridges simultaneously to understand and control the optical properties of this type of nanostructures. Finally, the potential of multiplexed Raman detection and imaging with RNNPs and the high-speed, high-resolution Raman bio-imaging of Au-RNNPs inside cells with a wide-field Raman imaging setup with liquid crystal tunable filter are demonstrated. Our results provide strategies and principles in designing and synthesizing plasmonically enhanced nanostructures and show potential for detecting and imaging Raman nanoprobes in a highly specific, sensitive and multiplexed manner.

Abstract
The broken symmetry of Janus nanostructures (JNs) provides a distinctive means to express drastically different chemical and physical characters within a single particle and acquire emergent properties usually inconceivable for homogeneous or symmetric nanostructures. In spite of their tremendous application potential, considerable challenges are encountered in identifying pathways to synthesize or assemble JNs with a controllable geometry and morphology. Here, we exploit the reverse process of growth, i.e. silver etching, to quantitatively control the structural and optical properties of the DNA-mediated Au-Ag JNs. The transmission electron microscopy and optical measurements, along with numerical simulations, present a comprehensive view of the etching dynamics and a detailed analysis of the influencing factors that provide handles for regulating the silver etching rate and progress. In addition, a novel type of composite JN is proposed and a model system is designed and engineered through dynamical control of the etching and DNA-hybridization processes.

Abstract
An ultrasensitive and highly selective electrochemical assay was first attempted by combining the rolling circle amplification (RCA) reaction with poly(thymine)-templated copper nanoparticles (CuNPs) for cascade signal amplification. As proof of concept, prostate specific antigen (PSA) was selected as a model target. Using a gold nanoparticle (AuNP) as a carrier, we synthesized the primer-AuNP-aptamer bioconjugate for signal amplification by increasing the primer/aptamer ratio. The specific construction of primer-AuNP-aptamer/PSA/anti-PSA sandwich structure triggered the effective RCA reaction, in which thousands of tandem poly(thymine) repeats were generated and directly served as the specific templates for the subsequent CuNP formation. The signal readout was easily achieved by dissolving the RCA product-templated CuNPs and detecting the released copper ions with differential pulse stripping voltammetry. Because of the designed cascade signal amplification strategy, the newly developed method achieved a linear range of 0.05-500 fg/mL, with a remarkable detection limit of 0.020 ± 0.001 fg/mL PSA. Finally, the feasibility of the developed method for practical application was investigated by analyzing PSA in the real clinical human serum samples. The ultrasensitivity, specificity, convenience, and capability for analyzing the clinical samples demonstrate that this method has great potential for practical disease diagnosis applications.

Abstract
Telomerase is a widely used tumor biomarker for early cancer diagnosis. On the basis of the combined use of aggregation-induced emission (AIE) fluorogens and quencher, a quencher group induced high specificity strategy for detection of telomerase activity from cell extracts and cancer patients' urine specimens was creatively developed. In the absence of telomerase, fluorescence background is extremely low due to the short distance between quencher and AIE dye. In the addition of telomerase, fluorescence enhances significantly. The telomerase activity in the E-J, MCF-7, and HeLa extracts equivalent to 5-10 000 cells can be detected by this method in ∼1 h. Furthermore, the distinguishing of telomerase extracted from 38 cancer and 15 normal urine specimens confirms the reliability and practicality of this protocol. In contrast to our previous results (Anal. Chem. 2015, 87, 6822-6827), these advanced experiments obtain more remarkable specificity.

Abstract
We demonstrate an ultrasensitive microRNA detection method based on an extremely simple probe with only fluorogens but without quencher groups. It avoids complex and difficult steps to accurately design the relative distance between the fluorogens and quencher groups in the probes. Furthermore, the assay could accomplish various detection limits by tuning the reaction temperature due to the different activity of exonuclease III corresponding to the diverse temperature. Specifically, 1 pM miR-21 can be detected in 40 min at 37 °C, and 10 aM (about 300 molecules in 50 μL) miR-21 could be discriminated in 7 days at 4 °C. The great specificity of the assay guarantees that the real 21 urine samples from the bladder cancer patients are successfully detected by our method.
