Abstract
Aptamers are single-stranded DNA or RNA molecules with a defined tertiary structure for molecular recognition. Numerous RNA aptamers with excellent binding affinity and specificity have been reported; they constitute an attractive reservoir of molecular recognition elements for biosensor development. However, RNA is relatively unstable owing to spontaneous hydrolysis and nuclease degradation. Thus, RNA aptamer-based biosensors are prone to producing false-positive signals. Here, we present an RNA aptamer biosensor design strategy that utilises an internal control to distinguish target binding from false-positive signals. The sequence of a chosen RNA aptamer is expanded so that it can form three consecutive short RNA-DNA duplexes with 1) a quencher-labelled DNA strand (Q(1)DNA), 2) a dual-fluorophore-labelled DNA strand (F(1)DNAF(2)) and 3) another quencher-labelled DNA strand (Q(2)DNA). The addition of a target releases Q(2)DNA from the duplex assembly, and produces the expected positive signal from F(2). However, the authenticity of target recognition is validated only if no signal is generated from F(1). We have successfully engineered two fluorescent reporters by using an RNA aptamer that binds thrombin and one that binds theophylline. Both reporters show the expected binding affinity and specificity, and are capable of reporting system malfunction when treated with nucleases and chemical denaturants. This strategy provides a simple and reliable way to ensure high-quality detection when RNA aptamers are employed as molecular-recognition elements.

Abstract
The process of "structure-switching" enables biomolecular switches to function as effective biosensing tools. Biomolecular switches can be activated or inactivated by binding to a specific target that triggers a precise conformational change in the biomolecules involved. Although many examples of aptamer-based biomolecular switches can be found in nature, substantial effort has been made in the last decade to engineer structure-switching aptamer sensors by coupling aptamers to a signal transduction method to generate a readout signal upon target binding to the aptamer domain. This chapter focuses on the progress of research on engineered structure-switching aptamer sensors. We begin by discussing the origin of the structure-switching aptamer design, highlight the key developments of structure-switching DNA aptamers for fluorescence-, electrochemistry-, and colorimetry-based detection, and introduce our recent efforts in exploring RNA aptamers to create structure-switching molecular sensors.

Abstract
Aptamers are single-stranded oligonucleotides that bind to targets with high affinity and selectivity. Their use as molecular recognition elements has emerged as a viable approach for biosensing, diagnostics, and therapeutics. Despite this potential, relatively few aptamers exist that bind to small molecules. Small molecules are important targets for investigation due to their diverse biological functions as well as their clinical and commercial uses. Novel, effective molecular recognition probes for these compounds are therefore of great interest. This paper will highlight the technical challenges of aptamer development for small molecule targets, as well as the opportunities that exist for their application in biosensing and chemical biology.

Abstract
In this work, a simple and label-free fluorescent method via fluorescent indicator displacement (FID) was proposed for enantioselectively determining d-enantiomer of arginine vasopressin (DV) using DV-specific DNA aptamer (V-apt) and one guanidiniophthalocyanine dye (Zn-DIGP). Zn-DIGP that preferentially binds to single-stranded DNA with fluorescence enhancement rather than duplexes occupies the long internal loop of V-apt and generates intensive fluorescence. Then DV is introduced into the solution containing Zn-DIGP and V-apt, and displaces the Zn-DIGP from the binding site of internal loop, leading to fluorescence decrease. But l-enantiomer cannot induce any fluorescence change due to the selectivity of V-apt. This established FID technique can detect DV with a detection limit of 100 nM and exhibits a broad linear range, and is able to discriminate enantiomers of arginine vasopressin unambiguously. Moreover chiral separation by chromatography, complicated experimental procedures and covalent modification of tags (such as organic dyes, redox-active metal complexes) are avoided in our strategy. This simple and label-free method is promising for fabricating diverse aptasensors to determine other biomolecules and drugs.

Abstract
Here we demonstrate for the first time that by physically adsorbing aptamer onto conductive film assembled via alternate adsorption of graphene/polyelectrolyte and methylene blue/polyelectrolyte, a label-free electrochemical aptasensor with high sensitivity and selectivity for peptide detection is constructed. Graphene multilayer derived from layer-by-layer assembly has played significant roles in this sensing strategy: allowing accumulation of methylene blue, facilitating electron transfer and providing much more adsorption site. As compared to previous electrochemical aptasensors, the current sensor based on graphene multilayer alternated with electroactive molecule layer offers extremely high capability for sensitive detection of target without interference of environmental surrounding. This electroactive probe-confined graphene multilayer confers great flexibility to combine with differential pulse voltammetry (DPV) together. In the presence of target d entiomer of arginine vasopressin (D-VP), the binding of peptide to aptamer block the electron transfer process of MB, leading to decreased current peak of DPV. By this way, this electrochemical aptasensor based on electroactive molecule-intercalated graphene multilayer provide highly sensitive and specific detection of D-VP with the lowest detectable concentration of 1 ng mL(-1) and a wide detection range from 1 to 265 ng mL(-1).

Abstract
Affinity probe capillary electrophoresis (APCE) assays, combining the separation power of CE with the specificity of interactions occurring between a target and a molecular recognition element (MRE), have become important analytical tools in many application fields. In this report, a rationalized strategy, derived from the structure-switching aptamer concept, is described for the design of a novel APCE mode dedicated to small molecule detection. Two assay configurations were reported. The first one, developed for the single-analyte determination, was based on the use of a cholesteryl-tagged aptamer (Chol-Apt) as the MRE and its fluorescein-labeled complementary strand (CS*) as the tracer (laser-induced fluorescence detection). Under micellar electrokinetic chromatography (MEKC) conditions, free CS* and the hybrid formed with Chol-Apt (duplex*) were efficiently separated (and then quantified) through the specific shift of the electrophoretic mobility of the cholesteryl-tagged species in the presence of a neutral micellar phase. When the target was introduced into the preincubated sample, the hybridized form was destabilized, resulting in a decrease in the duplex* peak area and a concomitant increase in the free CS* peak area. The second format, especially designed for multianalyte sensing, employed dually cholesteryl- and fluorescein-labeled complementary strands (Chol-CS*) of different lengths and unmodified aptamers (Apt). The size-dependent electrophoretic separation of different Chol-CS* forms from each other and from their corresponding duplexes* was also accomplished under MEKC conditions. The simultaneous detection of multiple analytes in a single capillary was performed by monitoring accurately each target-induced duplex-to-complex change. This method could expand significantly the potential of small solute APCE analysis in terms of simplicity, adaptability, generalizability, and high-throughput analysis capability.

Abstract
Of the known intelligently-operating systems, the majority can undoubtedly be classed as being of biological origin. One of the notable differences between biological and artificial systems is the important fact that biological materials consist mostly of chiral molecules. While most biochemical processes routinely discriminate chiral molecules, differentiation between chiral molecules in artificial systems is currently one of the challenging subjects in the field of molecular recognition. Therefore, one of the important challenges for intelligent man-made sensors is to prepare a sensing system that can discriminate chiral molecules. Because intermolecular interactions and detection at surfaces are respectively parts of supramolecular chemistry and interfacial science, chiral sensing based on supramolecular and interfacial concepts is a significant topic. In this review, we briefly summarize recent advances in these fields, including supramolecular hosts for color detection on chiral sensing, indicator-displacement assays, kinetic resolution in supramolecular reactions with analyses by mass spectrometry, use of chiral shape-defined polymers, such as dynamic helical polymers, molecular imprinting, thin films on surfaces of devices such as QCM, functional electrodes, FET, and SPR, the combined technique of magnetic resonance imaging and immunoassay, and chiral detection using scanning tunneling microscopy and cantilever technology. In addition, we will discuss novel concepts in recent research including the use of achiral reagents for chiral sensing with NMR, and mechanical control of chiral sensing. The importance of integration of chiral sensing systems with rapidly developing nanotechnology and nanomaterials is also emphasized.
