Abstract
In this work, we report the construction of a novel electrochemical device for molecular diagnosis of hepatitis B virus in the blood plasma of infected patients, using graphite electrodes functionalized with poly(4-aminophenol) and sensitized with a specific DNA probe. The recognition of genomic DNA was evaluated by electrochemical techniques (DPV and EIS) and scanning electron microscopy. The genosensor was efficient in detecting genomic DNA with a linear range from 1.176 to 4.825 μg mL-1 and detection limit of 35.69 ng mL-1 (4.63 IU ml-1 or 25.93 copies.ml-1), which is better than the 10.00 IU ml-1 limit of reference method, real-time PCR, used in point of care. EIS analysis shows that the genosensor resistance increased exponentially with the concentration of the genomic DNA target. This novel platform has advantages to its applicability in real samples, such as good sensitivity, selectivity, low sample volume, and fast assay time (36 min), thus interesting for application in the diagnosis of hepatitis B virus in blood plasma. Also, the ease of synthesis of the low-cost polymer by electrosynthesis directly on the electrode surface allows the translation of the platform to portable devices.

Abstract
Rheumatoid arthritis (RA), an autoimmune and chronic inflammatory disorder, is an incurable disease. We developed a peptide-based electrochemical sensor using electrochemical impedance spectroscopy that can be used to detect autoantibodies for RA diagnostics. We first validated that the developed peptide showed high sensitivity and could compliment the current gold standard method of an anti-cyclic citrullinated peptide antibody (anti-CCP) ELISA. The developed peptide can be modified on the nanogold surface of the working electrode of sensing chips through the method of a self-assembling monolayer. The sensing process was first optimized using a positive control cohort and a healthy control cohort. Subsequently, 10 clinically confirmed samples from RA patients and five healthy control samples were used to find the threshold value of the impedance between RA and healthy subjects. Furthermore, 10 clinically confirmed samples but with low values of anti-CCP autoantibodies were used to evaluate the sensitivity of the present method compared to the conventional method. The proposed method showed better sensitivity than the current conventional anti-CCP ELISA method.

Abstract
Fluorine doped tin oxide (FTO) electrochemical immunosensor has been developed for rapid detection of urokinase type plasminogen activator receptor (uPAR) - a biomarker for cancer. uPAR is a GPI-anchored cell membrane receptor that shows increased expression in many types of human cancers which include breast, prostate, colorectal, and non-small cell lung cancer. In this study, a novel ultrasensitive FTO graphene nanosheets based electrode was used as a working probe to analyze the interaction between urokinase plasminogen activator (uPA) and monoclonal uPAR antibody (Ab). Graphene nanosheets (GNS) exhibited high conductivity, thereby increasing the sensitivity of the immunochemical assay. GNS were coupled with uPAR-Ab via carbodiimide activation chemistry with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC)/N-hydroxysuccinimide (NHS) as a heterobifunctional crosslinker. The confirmation of immobilization events was done by biophysical methods such as UV-Vis spectroscopy, fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM), differential pulse (DPV), and cyclic voltammetry (CV). The immobilization conditions were optimized in accordance with the best sensor response. Under optimum conditions, the proposed sensor displayed wide linear detection range (1 fM to 1 μM) with a detection limit of 4.8 fM in standard. The developed sensor was profitably engaged to detect uPA in spiked serum samples up to 9.2 pM. Furthermore, the developed uPAR immunosensor showed good reproducibility, repeatability, and storage stability (75% of initial activity observed up to 4 weeks). FTO/GNS/uPAR-Ab/uPA-Ag immunosensor displayed acceptable performance for detection of uPA and exhibited low detection limit with high reproducibility. The proposed immunosensor is 'easy to use', highly specific, and can be used as a quantitative tool making it a tenable alternate for the detection of uPAR in cancer patients.

Abstract
Juvenile idiopathic arthritis (JIA) is a wide group of diseases, characterized by synovial inflammation and joint tissue damage. Due to the delay in the implementation of biomarkers into clinical practice and the association with severe sequels, there is an imperative need for new JIA diagnosis strategies. Electrochemical biosensors based on screen-printed electrodes and peptides are promising alternatives for molecular diagnosis. In this work, a novel biosensor for detecting juvenile idiopathic arthritis (JIA) was developed based on the immobilization of the PRF+1 mimetic peptide, as recognition biological element, on the surface of screen-printed carbon electrode. This biosensor was able to discriminate the JIA positive and negative serum samples from different individuals using differential pulse voltammetry, presenting limits of detection and quantification in diluted samples of 1:784 (v/v) and 1:235 (v/v), respectively. Evaluation by electrochemical impedance spectroscopy showed RCT 3 times higher for JIA positive sample than for a pool of human serum samples from healthy individuals. Surface analysis of the biosensor by atomic force microscopy, after contact with JIA positive serum, presented great globular clusters irregularly distributed. The long-term stability of the biosensor was evaluated, remaining functional for over 40 days of storage (after storage at 8°C). Therefore, a simple, miniaturized and selective biosensor was developed, being the first one based on mimetic peptide and screen-printed carbon electrode, aiming at the diagnosis of the juvenile idiopathic arthritis in real serum samples.

Abstract
This work designed a three-component polymer for the preparation of polymer dots (Pdots). The polymer contained 9-(diphenylmethylene)-9H-fluorene (DPF), 9,9-dioctyl-9H-fluorene (DOF) and 1,1'-binaphthyl moieties, and was synthesized via Pd-catalyzed Suzuki reaction. It exhibited obvious yellow-colored aggregation-induced emission (AIE) for fluorescence enhancement at 543nm via an intramolecular fluorescence resonance energy transfer from DOF moiety to DPF moiety. The Pdots prepared by nanoprecipitation could be conveniently cast on electrode surface and showed a stable anodic electrochemiluminescence (ECL) emission in the presence of triethylamine as a co-reactant. The ECL emission could be effectively quenched by rhodamine B via resonance energy transfer, which led to an "off-on" switch for the design of ECL sensing methodology. Using Pb2+ as a target model, an ECL aptasensor for the detection of trace Pb2+ was proposed, which showed a linear range of 100pM to 1.0μM with a detection limit down to 38.0pM This work demonstrated the first Pdots prepared with AIE-active polymer for highly efficient ECL sensing.
