Abstract
Due to their programmable structures, many aptamers can be readily split into two halves while still retaining their target binding function. While split aptamers are prevalent in the biosensor field, fundamental studies of their binding are still lacking. In this work, we took advantage of the fluorescence enhancement property of a new aptamer named OTC5 that can bind to tetracycline antibiotics to compare various split aptamers with the full-length aptamer. The split aptamers were designed to have different stem lengths. Longer stem length aptamers showed similar dissociation constants (Kd) to the full-length aptamer, while a shorter stem construct showed an 85-fold increase in Kd. Temperature-dependent fluorescence measurements confirmed the lower thermostability of split aptamers. Isothermal titration calorimetry indicated that split aptamer binding can release more heat but have an even larger entropy loss. Finally, a colorimetric biosensor using gold nanoparticles was designed by pre-assembling two thiolated aptamer halves, which can then link gold nanoparticles to give a red-to-blue color change.

Abstract
Early cancer screening enables timely detection of carcinogenesis, and aids in prompt clinical intervention. Herein, we report on the development of a simple, sensitive, and rapid fluorometric assay based on the aptamer probe (aptamer beacon probe, ABP) for monitoring the energy-demand biomarker adenosine triphosphate (ATP), an essential energy source that is released into the tumor microenvironment. Its level plays a significant role in risk assessment of malignancies. The operation of the ABP for ATP was examined using solutions of ATP and other nucleotides (UTP, GTP, CTP), followed by monitoring of ATP production in SW480 cancer cells. Then, the effect of a glycolysis inhibitor, 2-deoxyglucose (2-DG), on SW480 cells was investigated. The stability of predominant ABP conformations in the temperature range of 23-91 °C and the effects of temperature on ABP interactions with ATP, UTP, GTP, and CTP were evaluated based on quenching efficiencies (QE) and Stern-Volmer constants (KSV). The optimized temperature for best selectivity of ABP toward ATP was 40 °C (KSV = 1093 M-1, QE = 42%). We have found that the inhibition of glycolysis in SW480 cancer cells by 2-deoxyglucose resulted in lowering of ATP production by 31.7%. Therefore, monitoring and modulation of ATP concentration may aid in future cancer treatment.

Abstract
The development of sensitive adenosine triphosphate (ATP) sensors is imperative due to the tight relationship between the physiological conditions and ATP levels in vivo. Herein, a fluorescent aptasensor for ATP is presented, which adopts a strategy that combines a split aptamer and a DNAzyme/walker with terminal deoxynucleotidyl transferase (TDT)-assisted formation of DNA-AgNCs to realize fluorescence detection of ATP. A multifunctional oligonucleotide sequence is rationally designed, which integrates a split aptamer, a DNAzyme and a DNA walker. Both multifunctional oligonucleotide and its substrate strand are connected to the surface of Fe3O4@Au nanoparticles via Au-S bonds. The existence of ATP can induce the formation of the complete aptamer, and then activate the DNAzyme to circularly cleave the substrate strand, leaving 2',3'-cyclophosphate at the 3'end of the strand. This blocks the polymerization of dCTP to form poly(C) even in the presence of TDT and dCTP, due to the lack of free 3'-OH. In contrast, when ATP is absent, the DNAzyme/walker cannot work and then TDT catalyzes the formation of poly(C) at the free 3'-OH of the substrate strand, which is subsequently utilized as the template to prepare DNA-AgNCs. The fluorescence response derived from AgNCs thus reflects the ATP concentration. Under the optimum conditions, the aptasensor shows a linear response range from 5 nM to 10 000 nM, with a detection limit of 0.27 nM. The level of ATP in human serum can be effectively measured by the aptasensor with good recovery, indicating its application potential in medical samples.

Abstract
Simply synthetized gold nanoparticles have been highly used in medicine and biotechnology as a result of their biocompatibility, conductivity, and being easily functionalized with biomolecules such as aptamer. Aptamer-conjugated gold nanoparticle structures synergically possess characteristics of both aptamer and gold nanoparticles including high binding affinity, high biocompatibility, enhanced target selectivity, and long circulatory half-life. Aptamer-conjugated gold nanoparticles have extensively gained considerable attention for designing of biosensing systems due to their interesting optical and electrochemical features. Moreover, biosensors based on aptamer-gold nanoparticles are easy to use, with fast response, and inexpensive which make them ideal in individualized medicine, disease markers detection, food safety, and so forth. Moreover, due to high selectivity and biocompatibility of aptamer-gold nanoparticles, these biosensing platforms are ideal tools for targeted drug delivery systems. The application of this nanostructure as diagnostic and therapeutic tool has been developed for detection of cancer in the early stage by detecting cancer biomarkers, pathogens, proteins, toxins, antibiotics, adenosine triphosphate, and other small molecules. This review obviously demonstrates that this nanostructure effectively is applicable in the field of biomedicine and possesses potential of commercialization aims.

Abstract
Close-packed hexagonal array nanopores are widely used both in research and industry. A self-ordered nanoporous structure makes anodic aluminum oxide (AAO) one of the most popular nanomaterials. This paper describes the main formation mechanisms for AAO, the AAO fabrication process, and optical sensor applications. The paper is focused on four types of AAO-based optical biosensor technology: surface-Enhanced Raman Scattering (SERS), surface Plasmon Resonance (SPR), reflectometric Interference Spectroscopy (RIfS), and photoluminescence Spectroscopy (PL). AAO-based optical biosensors feature very good selectivity, specificity, and reusability.

Abstract
Aptamers are single-stranded nucleic acid sequences that can bind to target molecules with high selectivity and affinity. Most aptamers are screened in vitro by a combinatorial biology technique called systematic evolution of ligands by exponential enrichment (SELEX). Since aptamers were discovered in the 1990s, they have attracted considerable attention and have been widely used in many fields owing to their unique advantages. In this review, we present an overview of the advancements made in aptamers used for biosensors and targeted therapy. For the former, we will discuss multiple aptamer-based biosensors with different principles detected by various signaling methods. For the latter, we will focus on aptamer-based targeted therapy using aptamers as both biotechnological tools for targeted drug delivery and as targeted therapeutic agents. Finally, challenges and new perspectives associated with these two regions were further discussed. We hope that this review will help researchers interested in aptamer-related biosensing and targeted therapy research.

Abstract
Developing a sensitive, low-cost and general sensing platform for the analysis of a DNA biomarker and its mutation is important for early cancer screening. In our work, the tumor suppressor gene-p53 DNA was chosen as the model DNA biomarker due to its vital role in preventing oncogene cancer-inhibiting activity through mediating cellular proliferation and apoptosis. Compared with tumor biopsy, the quantification of p53 DNA and its mutation in biofluids (such as urine) is more convenient due to its simple operation and non-invasiveness. Herein, a label-free amplified fluorescence assay has been developed for p53 DNA in urine samples through the KFP polymerase-driven double strand displacement reactions and a magnetic nanoprobe. First, the ssDNA probe (RP) was designed with antisense sequences for p53 DNA and the Nb.BbvCI endonuclease recognition site. In the presence of p53 DNA, the formed dsDNA between RP and p53 DNA served as an engaging primer to initiate the first strand displacement reaction (SDA) under the action of KFP DNA polymerase and Nb.BbvCI, generating abundant short ssDNA (primer). Subsequently, the resulting primers will initiate the downstream SDA through the primer-hairpin DNA (HPa) binding, opening up, and extension of HPb and HPc under the action of KFP DNA polymerase. In the process of this final DNA polymerization reaction, the primer hybridized on HPa is released and goes on to initiate another round, forming plenty of duplex Y-shaped DNA. With the integration of SYBR Green I (SG I) into these duplex DNA, the amplified label-free fluorescence detection platform for p53 DNA can be achieved. Moreover, a biotin modified nanoprobe (bio-CP) was used to capture the superfluous HP. By performing the separation function, the binding of superfluous HP and SG could be avoided and a low background can be acquired. Benefiting from the abundant SG intercalation sites of Y-shaped DNA and low background signals, this method showed excellent sensitivity with a detection limit of 0.012 nM, and the p53 DNA in urine samples was evaluated, offering a powerful tool for biomedical research and clinical diagnosis.

Abstract
In analogy to split-protein systems, which rely on the appropriate fragmentation of protein domains, split aptamers made of two or more short nucleic acid strands have emerged as novel tools in biosensor set-ups. The concept relies on dissecting an aptamer into a series of two or more independent fragments, able to assemble in the presence of a specific target. The stability of the assembled structure can further be enhanced by functionalities that upon folding would lead to covalent end-joining of the fragments. To date, only a few aptamers have been split successfully, and application of split aptamers in biosensing approaches remains as promising as it is challenging. Further improving the stability of split aptamer target complexes and with that the sensitivity as well as efficient working modes are important tasks. Here we review functional nucleic acid assemblies that are derived from aptamers and ribozymes/DNAzymes. We focus on the thrombin, the adenosine/ATP and the cocaine split aptamers as the three most studied DNA split systems and on split DNAzyme assemblies. Furthermore, we extend the subject into split light up RNA aptamers used as mimics of the green fluorescent protein (GFP), and split ribozymes.

Abstract
The self-assembly of plasmonic nanoparticles provides a powerful approach to generate surface-enhanced Raman scattering (SERS), which promotes the actual applications in chemical and biomolecular analyses. Herein, we developed a facile SERS sensing strategy for an ATP assay with a 3-D DNA nanomachine that walks by the Exo III cleavage, leading to the formation of AuNP aggregates, which resulted in the enhancement of the electromagnetic field. Depending on the target-activated Exo III cleavage, the 3-D nanomachine can walk along the 3-D track on the surface of AuNPs and generate self-assembled hot-spots to enhance the SERS signal of a Raman dye, allowing a homogenous assay of the ATP concentration with high sensitivity and reproducibility. Under optimized experimental conditions, the biosensor detected ATP with a widened dynamic range from 1 pM to 1 × 105 pM with a limit of detection of up to 0.29 pM. Hence, the novel strategy provides a useful and practical platform for the SERS assay of ATP with high sensitivity and repeatability. Besides, this platform shows great potential for applications in high-throughput assays for drug screening and clinical diagnostics.

Abstract
Surface-enhanced Raman spectroscopy (SERS) as one of the effective tools for sensitive and selective detection of biomolecules has attracted tremendous attention. Here, we construct a versatile biomolecular detection platform based on photo-induced enhanced Raman spectroscopy (PIERS) effect for ultrasensitive detection of multiple analytes. In our PIERS sensor, we exploit the molecular recognition capacity of aptamers and the high affinity of aptamers with analyte to trigger TiO2@AgNP substrates binding with Raman tag-labeled gold nanoparticles probes via analyte, thus forming sandwich complexes. Additionally, combining plasmonic nanoparticles with photo-activated substrates allows PIERS sensor to achieve increased sensitivity beyond the normal SERS effect upon ultraviolet irradiation. Accordingly, the PIERS can be implemented for analysis of multiple analytes by designing different analyte aptamers, and we further demonstrate that the constructed PIERS sensor can serve as a versatile detection platform for sensitively analyzing various biomolecules including small molecules (adenosine triphosphate (ATP), limit of detection (LOD) of 0.1 nM), a biomarker (thrombin, LOD of 50 pM), and a drug (cocaine, LOD of 5 nM). Therefore, this versatile biomolecular detection platform based on PIERS effect for ultrasensitive detection of multiple analytes holds great promise to be a practical tool.
