Abstract
Improved outcomes for many types of cancer achieved during recent years is due, among other factors, to the earlier detection of tumours and the greater availability of screening tests. With this, non-invasive, fast and accurate diagnostic devices for cancer diagnosis strongly improve the quality of healthcare by delivering screening results in the most cost-effective and safe way. Biosensors for cancer diagnostics exploiting aptamers offer several important advantages over traditional antibodies-based assays, such as the in-vitro aptamer production, their inexpensive and easy chemical synthesis and modification, and excellent thermal stability. On the other hand, electrochemical biosensing approaches allow sensitive, accurate and inexpensive way of sensing, due to the rapid detection with lower costs, smaller equipment size and lower power requirements. This review presents an up-to-date assessment of the recent design strategies and analytical performance of the electrochemical aptamer-based biosensors for cancer diagnosis and their future perspectives in cancer diagnostics.

Abstract
Cancer is the second most extended disease during the world with an improved death rate over the past several time. Due to the restrictions of cancer analysis methods, the patient's real survival rate is unknown. Therefore early stage diagnosis of cancer is crucial for its strong detection. Bio-analysis based on biomarkers may help to overcome this problem. Aptamers can be employed as high-affinity tools for cancer detection. The utilization of aptamer-based strategy in cancer investigation and strategy shows new opportunities in biotechnology. The label-free system is an important method to study biomolecules in different sizes, such as biomarkers in real-time because of their greatest sensitivity, selectivity, and multi examination. In this review (with 75 references), excellent features of the label-free aptasensors on the sensitive and accurate monitoring of cancer biomarkers were discussed. Also, the role of advanced of nanomaterials on the construction of label-free aptasensors were investigated. In addition, application of different detection methods such as electrochemical, optical, electronic, and photoelectrochemical (PEC), electrochemiluminescence (ECL) were surveyed. Finally, advantages and limitation of different strategies on the early stage diagnosis of cancer biomarkers were discussed. This article has been updated until July 2020.

Abstract
In this research, a novel signal-on aptasensor for highly sensitive detection of zearalenone (ZEN) was reported based on target-induced amplification strategy. Specifically, chitosan functionalized acetylene black and multi-walled carbon nanotubes (CS@AB-MWCNTs) nanocomposite with large specific surface area and excellent conductivity was synthesized and served as the sensing platform. In addition, carboxylated graphene oxide-labeled ZEN binding aptamer (CGO-ZBA) would specifically recognized with ZEN to detach from the electrode, allowing the electrochemical signal of [Fe(CN)6]3-/4- increased more obviously. Under the optimal conditions, the proposed aptasensor exhibited exceptional detection performances for ZEN with a linear range from 10 fg mL-1 to 1 ng mL-1 and a low limit of detection of 3.64 fg mL-1. Given its great sensitivity, excellent selectivity, satisfactory stability and reproducibility, this method would provide a promising application for ZEN and other biomolecules by replacing the corresponding nucleicacidsequences.

Abstract
The growing number of various diseases and the increase of environmental contamination are the causes for the development of novel methods for their detection. The possibility of the application of affinity-based biosensors for such purposes seems particularly promising as they provide high selectivity and low detection limits. Recently, the usage of hybrid antibody-aptamer sandwich constructs was shown to be more advantageous in terms of working parameters in comparison to aptamer-based and immune-based biosensors. This review is focused on the usage of hybrid antibody-aptamer receptor layers for the determination of clinically and environmentally important target molecules. In this work, antibodies and aptamer molecules are characterized and the methods of their immobilization as well as analytical signal generation are shown. This is followed by the critical presentation of examples of hybrid sandwich biosensors that have been elaborated in the past 12 years.

Abstract
Platelet-derived growth factor (PDGF-BB), a significant serum cytokine, is an important protein biomarker in diagnosis and recognition of cancer, which straightly rolled in proceeding of various cell transformations, including tumor growth and its development. Fibrosis, atherosclerosis are certain appalling diseases, which PDGF-BB is near to them. Generally, the expression amount of PDGF-BB increases in human life-threatening tumors serving as an indicator for tumor angiogenesis. Thus, identification and quantification of PDGF-BB in biomedical fields are particularly important. Affinity chromatography, immunohistochemical methods and enzyme-linked immunosorbent assay (ELISA), conventional methods for PDGF-BB detection, requiring high-cost and complicated instrumentation, take too much time and offer deficient sensitivity and selectivity, which restrict their usage in real applications. Hence, it is essential to design and build enhanced systems and platforms for the recognition and quantification of protein biomarkers. In the past few years, biosensors especially aptasensors have been received noticeable attention for the detection of PDGF-BB owing to their high sensitivity, selectivity, accuracy, fast response, and low cost. Since the role and importance of developing aptasensors in cancer diagnosis is undeniable. In this review, optical and electrochemical aptasensors, which have been applied by many researchers for PDGF-BB cancer biomarker detection, have been mentioned and merits and demerits of them have been explained and compared. Efforts related to design and development of aptamer-based biosensors using nanoparticles for sensitive and selective detection of PDGF-BB have been reviewed considering: Aptamer importance as recognition elements, principal, application and the recent improvements and developments of aptamer based optical and electrochemical methods. In addition, commercial biosensors and future perspectives for rapid and on-site detection of PDGF-BB have been summarized.

Abstract
We synthesized two kinds of carbon-based nanocomposites of silver nanoclusters (AgNCs). An aptamer for targeted platelet-derived growth factor-BB (PDGF-BB) detection was used as the organic phase to produce AgNCs@Apt, three dimensional reduced graphene oxide@AgNCs@Aptamer (3D-rGO@AgNCs@Apt), and graphene quantum dots@AgNCs@Aptamer (GQD@AgNCs@Apt) nanocomposites. The formation mechanism of the developed nanocomposites was described by detailed characterizations of their chemical and crystal structures. Subsequently, the as-synthesized nanoclusters containing aptamer strands were applied as the sensitive layers to fabricate a novel electrochemical aptasensor for the detection of PDGF-BB, which may be directly used to determine the target protein. Electrochemical impedance spectra showed that the developed 3D-rGO@AgNCs@Apt-based biosensor exhibited the highest sensitivity for PDGF-BB detection among three kinds of fabricated aptasensors, with an extremely low detection limit of 0.82pgmL-1. In addition, the 3D-rGO@AgNCs@Apt-based biosensor showed high selectivity, stability, and applicability for the detection of PDGF-BB. This finding indicated that the AgNC-based nanocomposites prepared by a one-step method could be used as an electrochemical biosensor for various detection procedures in the biomedical field.

Abstract
Thin films of organic moiety functionalized carbon nanotubes (CNTs) from a very well-dispersed aqueous solution were designed on a screen printed transducer surface through a single step directed assembly methodology. Very high density of CNTs was obtained on the screen printed electrode surface, with the formation of a thin and uniform layer on transducer substrate. Functionalized CNTs were characterized by X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller (BET) surface area analyzer methodologies, while CNT coated screen printed transducer platform was analyzed by scanning electron microscopy (SEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The proposed methodology makes use of a minimum amount of CNTs and toxic solvents, and is successfully demonstrated to form thin films over macroscopic areas of screen printed carbon transducer surface. The CNT coated screen printed transducer surface was integrated in the fabrication of electrochemical aptasensors for breast cancer biomarker analysis. This CNT coated platform can be applied to immobilize enzymes, antibodies and DNA in the construction of biosensor for a broad spectrum of applications.

Abstract
In the development of disease diagnoses, rapid responses to and accurate selectivity for target analytes are critical aspects. As one diagnostic approach, biosensors with high sensitivity and selectivity are investigated to detect disorder factors (e.g., endocrine disruptors and cancer oncoproteins). In this report, we demonstrate an aptamer-functionalized multidimensional hybrid conducting-polymer (3-carboxylated polypyrrole) plate (A_MHCPP) based field-effect transistor (FET) sensor to detect a platelet-derived growth factor (PDGF-BB). The multidimensional hybrid conducting-polymer plates (MHCPPs) are formed on the graphene surface by using electrodeposition and vapor deposition polymerization (VDP) steps. The amine-functionalized PDGF-B binding aptamers are then immobilized on the carboxylated polypyrrole surface by means of covalent bond formation (-CONH). The prepared FET sensors present high sensing ability toward PDGF-BB - as low as 1.78 fM among interfering biomolecules at room temperature.

Abstract
An electrochemical aptasensor is a compact analytical device where the bioreceptor (aptamer) is coupled to a transducer surface to convert a biological interaction into a measurable signal (current) that can be easily processed, recorded and displayed. Since the discovery of the Systematic Evolution of Ligands by Enrichment (SELEX) methodology, the selection of aptamers and their application as bioreceptors has become a promising tool in the design of electrochemical aptasensors. Aptamers present several advantages that highlight their usefulness as bioreceptors such as chemical stability, cost effectiveness and ease of modification towards detection and immobilization at different transducer surfaces. In this review, a special emphasis is given to the potential use of electrochemical aptasensors for the detection of protein disease biomarkers using voltammetry techniques. Methods for the immobilization of aptamers onto electrode surfaces are discussed, as well as different electrochemical strategies that can be used for the design of aptasensors.

Abstract
Using platelet-derived growth factor B chain dimer (PDGF-BB) as the model target, a background current eliminated electrochemical aptameric sensing platform for highly sensitive and signal-on detection of protein is proposed in this paper. Successful fabrication of the biosensor depends on ingenious design of aptamer probe, which contains the aptamer sequence for PDGF-BB and the recognition sequence for EcoRI endonuclease. In the absence of PDGF-BB, the ferrocene labeled aptamer probe folds into a hairpin structure and forms a recognition site for EcoRI. By treatment with endonuclease, the specific and cleavable double-stranded region is cut off and redox-active ferrocene molecule is removed from the electrode surface, and almost no peak current is observed. When binding with target protein, the designed aptamer probe changes its conformation and dissociates the recognition double strand. The integrated aptamer probe is maintained when exposing to EcoRI endonuclease, resulting in obvious peak current. Therefore, a signal-on and sensitive sensing strategy for PDGF-BB detection is fabricated with eliminated background current. Under the optimized experimental conditions, a wide linear response range of 4 orders of magnitude from 20pgmL(-1) to 200ngmL(-1) is achieved with a detection limit of 10pgmL(-1). Moreover, the present aptameric platform is universal for the analysis of a broad range of target molecules of interest by changing and designing the sequence of aptamer probe.

Abstract
In the present study, a versatile "signal-on" electrochemical aptasensor based on a triple-helix molecular switch has been developed. An aptamer probe is designed to hybridize with the methylene blue (MB)-modified DNA capture probe immobilized on the gold electrode to form rigid triple-helix DNA, impeding the efficient electron transfer of MB to the electrode and resulting in the decreased oxidation peak current of MB. However, upon introduction of the perfectly matched target, for example, human α-thrombin (Tmb), the interaction between Tmb and the aptamer probe leads to the dissociation of the triple-helix DNA structure and thereby liberates the MB-modified end of the capture probe, allowing the MB to collide with the electrode surface and resulting in an increase of the oxidation peak currents of MB. Therefore, the sensitive signal-on detection of Tmb is realized, and the detection limit of Tmb is 0.12 nM. The proposed approach also demonstrates excellent regenerability, reproducibility and stability. Additionally, it also has the advantages of simplicity in design and easy operation. The success in the present biosensor provides a promising alternative to the electrochemical detection of a variety of analytes and may have potential applications in point-of-care testing and clinical diagnosis.

Abstract
Highly sensitive detection of proteins is of great importance for effective clinical diagnosis and biomedical research. However, so far most detection methods rely on antibody-based immunoassays and are usually laborious and time-consuming with poor sensitivity. Here, we developed a simple and ultra-sensitive method to detect a biomarker protein-thrombin by taking advantage of the fluorescent probe Perylene tetracarboxylic acid diimide (PTCDI) derivatives and thrombin aptamer. The water-soluble dye PTCDI shows strong fluorescence in buffer solution for the existence of free dye monomer, but becomes weak after aggregation through self-assembly on nucleic acid aptamer. In the presence of thrombin, it specifically binds to thrombin aptamer which causes the conformational transition between aptamer and PTCDI and results in a significant fluorescence recovery. The results showed that as low as 40 pM of thrombin could be detected by this method. The high sensitivity of the developed sensing system mainly attributes to the ultra-sensitivity of the fluorescence intensity changes of PTCDI. With the specificity of aptamer, the assay exhibited high selectivity for thrombin against three other proteins (bovine serum albumin, lysozyme, mouse IgG) and 1% diluted fetal bovine serum. The detection method might be extended to sensitive detection of a variety of proteins for its advantages of isothermal conditions required, simple and rapid without multiple separation and washing steps.

Abstract
Precise selectivity and rapid responses to target biomolecules are important in the development of biosensors. In particular, highly sensitive and selective biosensors have been used in clinical treatment to detect factors such as cancer oncoproteins and endocrine disruptors. Herein, highly sensitive liquid electrolyte field-effect transistor (FET) system biosensors were fabricated to detect platelet-derived growth factor (PDGF) using a PDGF-B binding aptamer conjugated with carboxylic polypyrrole-coated metal oxide-decorated carbon nanofibers (CPMCNFs) as the signal transducer. First, CPMCNFs were fabricated using vapor deposition polymerization (VDP) of the carboxylic pryrrole monomer (CPy) on metal oxide-decorated carbon nanofiber (MCNF) surfaces with no treatment for carbon surface functionalization. Furthermore, a 3 nm thick uniformly coated carboxylic polypyrrole (CPPy) layer was formed without aggregation. The CPMCNFs were integrated with the PDGF-B binding aptamer and immobilized on the interdigitated array substrate by covalent anchoring to produce a FET-type biosensor transducer. The PDGF-B binding aptamer conjugated CPMCNF (CPB-Apt) FET sensor was highly sensitive (5 fM) and extremely selective for isoforms of PDGFs. Additionally, the CPB-Apt FET sensor could be reused over a few weeks.

Abstract
Fast and accurate pathogen detection in aquatic environments is challenging in many biomedical studies and microbial diagnostic applications. In this study, we developed a real-time, continuous, and non-destructive single cell detection method using target specific aptamer-conjugated fluorescent nanoparticles (A-FNPs) and an optofluidic particle-sensor platform. A-FNPs selectively bound to the surfaces of target bacteria (Escherichia coli) and labeled them with high affinity and selectivity so that target bacteria can be countable particles in an optofluidic particle-sensor. A-FNP-labeled target bacterial complexes were detected by the optofluidic particle-sensing system, which provides rapid and continuous single-cell detection. A-FNPs selectively bound to E. coli with a dissociation constant of 0.83 nM, but did not bind Enterobacter aerogenes or Citrobacter freundii strains, which lacked affinity for the aptamer used. We demonstrated that our optofluidic device achieves a detection throughput of ~100 particles per second with high accuracy (~85%) in detecting single bacterial cells conjugated with A-FNPs. This approach can be immediately extended to the real-time, high-throughput detection of other microorganisms such as viruses that are selectively conjugated with A-FNPs. Collectively, these data suggest that optofluidic systems are widely applicable for the fast and continuous detection of microbial cells.

Abstract
Oncoprotein platelet derived growth factor-BB (PDGF-BB) is one of the most critical growth factors that regulates tumor growth and division. In this work, a highly sensitive and selective fluorescence resonance energy transfer (FRET) aptasensor for PDGF-BB detection based on the assembly of dye-labeled aptamer and graphene oxide (GO) is developed for the first time. Due to the non-covalent assembly between aptamer and GO, fluorescence quenching of the dye takes place because of FRET. In the presence of PDGF-BB, the binding between aptamer and PDGF-BB will disturb the interaction between aptamer and GO, and release the dye-labeled aptamer from the GO surface, resulting in restoration of the fluorophore fluorescence. Because of the high fluorescence quenching efficiency, unique structure, and electronic properties of GO, the GO aptasensor exhibits extraordinarily high sensitivity. We also demonstrate that two highly related molecular variants of PDGF (AA, AB) can be distinguished from PDGF-BB, which indicates the aptasensor has excellent selectivity. Such an aptasensor opens a rapid, selective and sensitive route for the detection of PDGF-BB and provides a promising strategy for other cancer-related proteins detections.

Abstract
A plug-and-play CD-like platform is used to perform a statistical detection of platelet derived growth factor (PDGF) proteins through aptamer-based surface functionalization of multiple microcantilever arrays. When PDGF proteins bind to aptamer coatings, the cantilevers deflect. The deflection response is monitored by optical read-out units from a commercial DVD-ROM device. We report on the use of an improved sensing platform which facilitates measurements under continuous liquid flow and with temperature control. Also, the mechanical wobbling of the DVD-ROM platform has been minimized and the scanning system has been optimized in order to detect cantilever deflections in liquid with nanometer scale resolution. The capability of the sensing platform is demonstrated by detection of clinically relevant concentrations of PDGF proteins. We present statistical measurements on 100 microcantilevers at different concentrations of PDGF, ranging from 10 nM to 400 nM. Hereby it is possible to reliably characterize the averaged mechanical response of cantilevers as a function of protein concentration.

Abstract
Aptamers are single-stranded nucleic acids that can be selected in vitro with special folding structures to bind to many different small-molecule, protein, and cellular targets. Over the past two decades, aptamers have become novel promising recognition elements for the fabrication of biosensors. These ‘aptasensors’ have several advantages over antibodies in that they are relatively easy to synthesise or modify in vitro, and can be appended with linkers and reporters for adaptation to various sensing strategies. In this chapter, we introduce the various electrochemical techniques that can be used as powerful readout methods for aptasensors, providing a brief introduction to aptamers and related electrochemical techniques, and then a detailed description of various branches within the field, including labelled strategies, unlabelled strategies, and enzyme-amplified strategies. For each type of approach, several basic and improved design principles will be addressed. It is hoped that, through this discussion, readers will get a sense of how several variables (aptamers, targets and redox reporters) are successfully combined with electrochemical techniques in order to produce a series of sensing platforms with high selectivity and sensitivity.

Abstract
The potential of aptamers as ligand binding molecule has opened new avenues in the development of biosensors for cancer oncoproteins. In this paper, a label-free detection strategy using signaling aptamer/protein binding complex for platelet-derived growth factor (PDGF-BB) oncoprotein detection is reported. The detection mechanism is based on the release of fluorophore (TOTO intercalating dye) from the target binding aptamer's stem structure when it captures PDGF. Amino-terminated three-dimensional carbon microarrays fabricated by pyrolyzing patterned photoresist were used as a detection platform. The sensor showed near linear relationship between the relative fluorescence difference and protein concentration even in the sub-nanomolar range with an excellent detection limit of 5pmol. This detection strategy is promising in a wide range of applications in the detection of cancer biomarkers and other proteins.

Abstract
Herein, we successfully fabricated a highly sensitive label-free electrochemical aptasensor for thrombin based on the amplification of graphene (Gra). The excellent electrochemical probe of nickel hexacyanoferrate nanoparticles (NiHCFNPs) was introduced to form Nafion-Graphene-NiHCFNPs (Nf-Gra-NiHCFNPs) nanocomposites membrane on the gold electrode. The employment of graphene not only enhanced the surface area of the electrode with increased NiHCFNPs immobilization, but also improved the conductivity of the electrode, which further effectively improved the sensitivity of this proposed aptasensor. Subsequently, AuNPs layer was formed to immobilize the thrombin aptamer (TBA) and enhance the stability of the composite monolayer mentioned above. Then, thiol-modified TBA was assembled onto the AuNPs layer. Thereafter, hexanethiol (HT) was employed to block the possible remaining active sites. With the dual amplification of Gra and AuNPs, the resulting aptasensor exhibited good current response to target thrombin with a wide linear range extended from 1 pM to 80 nM (the detection limit was 0.3 pM). Additionally, the morphologies of bare Au substrate, nickel hexacyanoferrate nanoparticles (NiHCFNPs) and nanocomposites were successfully characterized by atomic force microscopy (AFM).

Abstract
A simple and label-free aptasensor for sensitive and specific detection of cocaine was developed by measuring the change in electrochemical impedance spectra (EIS), based on the formation of a supramolecular aptamer fragments/substrate complex. An anticocaine aptamer was divided into two fragments, Cx and Cy. Three different sensing interfaces, called Au/Cx5S/MCE, Au/Cy3S/MCE and Au/Cy5S/MCE, were fabricated by immobilizing Cx or Cy on a gold electrode through modifying their 5' or 3' end with a thiolated group followed by the treatment with mercaptoethanol (MCE). The formation of the corresponding supramolecular aptamer fragments/cocaine complex was investigated via monitoring electrochemical impedance spectra in the presence of [Fe(CN)(6)](3-/4-). The interfacial electron transfer resistance (R(et)) was found to depend strongly on the cocaine concentration. Since the supramolecular aptamer fragments/cocaine complex was formed on the electrode surface, the sensing interface strongly affected the sensitivity of the aptasensor. Au/Cx5S/MCE was shown to have good sensitivity within a cocaine detection range of 0.1-20 μM. Moreover, MCE was shown to improve the sensitivity of the aptasensor greatly. Even without the help of amplification or labeling, cocaine concentrations as low as 100 nM could be easily detected by the impedimetric aptasensor developed. The specificity and regeneration of the cocaine aptasensor were also investigated and satisfactory results were obtained. The developed aptasensor was successfully applied to detect the cocaine in biological fluids.

Abstract
Oligonucleotide-based detection schemes that avoid chemical modification possess significant advantages, including simplified design, intrinsic affinity for targets, low cost and ease to extend applications. In this contribution, we developed a label-free self-locked bifunctional oligonucleotide probe (signaling probe) for the detection of different disease markers in parallel. Two signal enhancement techniques based on isothermal circular strand-displacement polymerization reaction, cyclical nucleic acid strand-displacement polymerization (CNDP) and cyclical common (nonnucleic acid) target-displacement polymerization (CCDP), were employed to implement the amplification assay for p53 gene and PDGF-BB, respectively. The attractive assay properties confirmed the effectiveness of isothermal polymerization in common biosensing systems without evolving any chemical modification: PDGF could be detected down to 0.87ng/mL, and a dynamic response range of 8-5000ng/mL was achieved; The capability to screen the p53 gene was also considerably improved, including the detection limit, sensitivity, dynamic range and so on. Moreover, because no any chemical modification of the signaling probe was acquired and different targets were separately detected in homogeneous solution. This interrogating platform exhibits the design flexibility, convenience, simplicity and cost-effectiveness. The success achieved here is expected to serve as a significant step toward the development of robust label-free oligonucleotide probes in biomarker profiling and disease diagnostics.

Abstract
The existing isothermal polymerization-based signal amplification assays are usually accomplished via two strategies: rolling circle amplification (RCA) and circular strand-displacement polymerization. In essence, the two techniques are based on cyclical nucleic acid strand-displacement polymerization (CNDP), limiting the application of isothermal polymerization in medical diagnosis and bioanalysis. In the present study, circular common target molecule (non-nucleic acid strand)-displacement polymerization (CCDP) is developed to amplify the fluorescence signal for biomolecule assays, extending isothermal polymerization to an aptameric system without any medium. Via combining an aptamer with a common hairpin DNA probe, we designed a self-blocked fluorescent bifunctional oligonucleotide probe (signaling probe) for the homogeneous parallel detection of two disease markers, PDGF-BB and the p53 gene. On the basis of CNDP and CCDP signal amplification, highly sensitive (e.g., detecting PDGF down to the concentration level of 1.8 × 10(-10) M) and selective detection (no interference even in the presence of a significantly higher concentration (7-200 times) of nontarget proteins) was accomplished, and the linear response range was considerably widened. Furthermore, the bifunctional signaling probe exhibits impressive simplicity, convenience, and short detection time. Herein, the design of the signaling probe was described, factors influencing fluorescence signal were investigated, analytical properties were characterized in detail, and the assay application in a complex medium was validated. The proposed biosensing scheme as a proof-of-concept is expected to promote the application of oligonucleotide probes in basic research and medical diagnosis.

Abstract
This paper reviews the advancements of a wide range of electrochemical aptamer-based biosensors, electrochemical aptasensors, for target analytes monitoring. Methods for immobilizing aptamers onto an electrode surface are discussed. Aptasensors are presented according to their detection strategies. Many of these are simply electrochemical, aptamer-based equivalents of traditional immunochemical approaches, sandwich and competition assays employing electroactive signaling moieties. Others, exploiting the unusual physical properties of aptamers, are signal-on (positive readout signal) and signal-off (negative readout signal) aptasensors based on target binding-induced conformational change of aptamers. Aptamer label-free devices are also discussed.

Aptamer-based and DNAzyme-linked colorimetric detection of cancer cells. Protein Cell 2010; 1:842-6.

Abstract
This paper reports a novel method to detect human leukemic lymphoblasts (CCRF-CEM cells). While the aptamer of the cancer cells was employed as the recognition element to target cancer cells, peroxidase-active DNAzyme was used as the sensing element to produce catalysis-induced colorimetric signals. The elegant architecture integrating the aptamer and DNAzyme made it feasible to detect cancer cells easily and rapidly by the color change of the substrate for DNAzyme. Experimental results showed that 500 cells can well indicate the cancer, while as control, 250,000 Islet Island Beta cells only show tiny signals, suggesting that the method proposed in this paper has considerable sensitivity and selectivity. Furthermore, since it does not require expensive apparatus, or modification or label of DNA chains, the method we present here is also cost-effective and conveniently operated, implying potential applications in future cancer diagnosis.

Abstract
The detection of platelet-derived growth factor (PDGF) via a solution-gate field-effect transistor (SGFET) has been demonstrated for the first time using aptamers immobilized on a diamond surface. Upon introduction of PDGF to the immobilized aptamer, a shift of 31.7 mV in the negative direction is observed at a source-drain current of -50 μA. A shift of 32.3 mV in the positive direction is detected after regeneration by SDS solution, indicating that the static measurement returns to its original value. These SGFETs operate stably within the large potential window of diamond (>3.0 V), and hence the surface channel does not need passivating with a thick insulating layer. Thereof, the immobilized aptamer channels have been exposed directly to the electrolyte solution without a gate insulator. Immobilization is achieved via aptamers covalently bonding to amine sites, thereby increasing the sensitivity of the biosensors. Diamond SGFETs have potential for the detection of PDGF and show durability against biological degradation after repeated usage and regeneration.

Abstract
A universal approach is proposed in this study for the development of an aptameric assay system for proteins based on aptamer structure-switching-triggered ligation-rolling circle amplification (L-RCA) upon target binding. The strategy chiefly depends on the competition for binding the aptamer probe between target protein and a complementary single-stranded DNA (CDNA) that can induce the circularization of the padlock probe. Introduction of target protein into the assay system inhibits the hybridization of the CDNA with the aptamer probe because of the formation of the target/aptamer duplex. The free CDNA can only hybridize with the padlock probe. With the assistance of DNA ligase, the padlock probe is circularized, and the subsequent RCA process can be accomplished by Phi 29 DNA polymerase. Each RCA product containing thousands of repeated sequences might hybridize with a large number of molecular beacons (detection probes), resulting in an enhanced fluorescence signal. In contrast, in the absence of target protein, no obvious change in the fluorescence intensity of the detection probe is observed. This signaling mode for target recognition and transduction events is based on the combination of aptamer recognition elements and L-RCA technology with high specificity and sensitivity. The proposed assay system not only exhibits excellent analytical characteristics (e.g., the detection limit on attomolar scale and a linear dynamic range of more than 3 orders of magnitude) but also possesses significant advantages over existing aptameric assays. The proposed strategy is universal since the sequences of aptamer probe, CDNA, and padlock probe could be easily designed to be compatible with the L-RCA based detection of other proteins without other conditions.

Abstract
We present a robust, sensitive, fluorescent- or radiolabel-free self-assembled optical diffraction biosensor that utilizes rolling circle amplification (RCA) and magnetic microbeads as a signal enhancement method. An aptamer-based sandwich assay was performed on microcontact-printed streptavidin arranged in 15 microm wide alternating lines and could specifically capture and detect platelet-derived growth factor B-chain (PDGF-BB). An aptamer served as a template for the ligation of a padlock probe, and the circularized probe could in turn be used as a template for RCA. The concatameric RCA product hybridized to biotinylated oligonuclotides which then captured streptavidin-labeled magnetic beads. In consequence, the signal from the captured PDGF-BB was amplified via the concatameric RCA product, and the diffraction gratings on the printed areas produced varying intensities of diffraction modes. The detected diffraction intensity and the density of the microbeads on the surface varied as a function of PDGF-BB concentration. Our results demonstrate a robust biosensing platform that is easy to construct and use and devoid of fluorescence microscopy. The self-assembled bead patterns allow both a visual analysis of the molecular binding events under an ordinary bright-field microscope and serve as a diffraction grating biosensor.

Abstract
The use of nanoscale materials (e.g., nanoparticles, nanowires, and nanorods) for electrochemical biosensing has seen explosive growth in recent years following the discovery of carbon nanotubes by Sumio Ijima in 1991. Although the resulting label-free sensors could potentially simplify the molecular recognition process, there are several important hurdles to be overcome. These include issues of validating the biosensor on statistically large population of real samples rather than the commonly reported relatively short synthetic oligonucleotides, pristine laboratory standards or bioreagents; multiplexing the sensors to accommodate high-throughput, multianalyte detection as well as application in complex clinical and environmental samples. This article reviews the status of biomolecular recognition using electrochemical detection by analyzing the trends, limitations, challenges and commercial devices in the field of electrochemical biosensors. It provides a survey of recent advances in electrochemical biosensors including integrated microelectrode arrays with microfluidic technologies, commercial multiplex electrochemical biosensors, aptamer-based sensors, and metal-enhanced electrochemical detection (MED), with limits of detection in the attomole range. Novel applications are also reviewed for cancer monitoring, detection of food pathogens, as well as recent advances in electrochemical glucose biosensors.

Abstract
In this paper, we report a novel electrochemical detection approach for platelet-derived growth factor (PDGF) via "sandwich" structure and gold nanoparticles (Au-NPs) mediated amplification technique. The "sandwich" structure is fabricated based on the fact that PDGF has two aptamer-binding sites, which makes it possible for one PDGF molecule to connect with two aptamers simultaneously. It is found that this electrochemical system with "sandwich" structure and Au-NPs can significantly amplify the signal of electrochemical probe [Ru(NH(3))(5)Cl](2+) for PDGF detection, and thus increase the detection sensitivity significantly. As a result, this PDGF detection approach obtains an extraordinarily low detection limit of 1 x 10(-14)M for purified samples, 1 x 10(-12)M for contaminated-ridden samples or undiluted blood serum. This detection approach can also exhibit good stability and excellent specificity.

Abstract
A new method for the determination of platelet-derived growth factor BB (PDGF-BB) was developed using an electrochemical immunosensor with an aptamer-primed, long-strand circular detection probe. Rabbit anti-human PDGF-B polyclonal antibody was immobilized on the electrode to serve as the capture antibody. The detection probe was synthesized via polymerase extension along a single-stranded circular plasmid DNA template with a primer headed by the anti-PDGF-B aptamer. In the presence of the analyte, the aptamer-primed circular probe was captured on the electrode via the formation of an antibody/PDGF-BB/aptamer sandwiched complex. The electroactivity indicator methylene blue was adsorbed on the electrode surface via the analyte-sandwiched complex with long-strand circular DNA, thus yielding a strong electrochemical signal for the quantification of PDGF-BB. This strategy allowed electrochemical detection with enormous signal amplification arising from the long-strand localized circular probe. The oxidation peak current of methylene blue in square wave voltammetric measurements showed a linear dependence on the concentration of PDGF-BB in the range from 50 to 500 ng mL(-1), with a detection limit as low as 18 pg mL(-1).
