Abstract
With the imminent needs of rapid, accurate, simple point-of-care systems for global healthcare industry, electrochemical biosensors have been widely developed owing to their cost-effectiveness and simple instrumentation. However, typical electrochemical biosensors for direct analysis of proteins in the human biological sample still suffer from complex biosensor fabrication, lack of general method, limited sensitivity, and matrix-caused biofouling effect. To resolve these challenges, we developed a general electrochemical sensing strategy based on a designed steric hindrance effect on an antibody surface layer. This strategy utilizes the interaction pattern of protein-G and immunoglobulin G (Fc and Fab regions), providing a steric hindrance effect during the target capturing process. The provided steric hindrance effect minimizes the matrix effect-caused fouling surface and altered the path of electron transfer, delivering a low-fouling and high-sensitivity detection of protein in complex matrices. Also, an enzyme-based horseradish peroxidase/hydroquinone/H2O2 transduction system can also be applied to the system, demonstrating the versatility of this sensing strategy for general electrochemical sensing applications. We demonstrated this platform through the detection of Tau protein and programming death ligand 1 with a subpico molar detection limit within 10 min, satisfying the clinical point-of-care requirements for rapid turnaround time and ultrasensitivity.

Abstract
Detection of biomarkers has raised much interest recently due to the need for disease diagnosis and personalized medicine in future point-of-care systems. Among various biomarkers, antibodies are an important type of detection target due to their potential for indicating disease progression stage and the efficiency of therapeutic antibody drug treatment. In this review, electrochemical and optical detection of antibodies are discussed. Specifically, creating a non-label and reagent-free sensing platform and construction of an anti-fouling electrochemical surface for electrochemical detection are suggested. For optical transduction, a rapid and programmable platform for antibody detection using a DNA-based beacon is suggested as well as the use of bioluminescence resonance energy transfer (BRET) switch for low cost antibody detection. These sensing strategies have demonstrated their potential for resolving current challenges in antibody detection such as high selectivity, low operation cost, simple detection procedures, rapid detection, and low-fouling detection. This review provides a general update for recent developments in antibody detection strategies and potential solutions for future clinical point-of-care systems.

Abstract
We present a low-cost, sensitive and specific DNA field-effect transistor sensor for the rapid detection of a common mutation to the tumour protein 53 gene (TP53). The sensor consists of a commercially available, low-cost, field-effect transistor attached in series to a gold electrode sensing pad for DNA hybridisation. The sensor has been predominantly optimised electrochemically, particularly with respect to open-circuit potentiometry as a route towards understanding potential (voltage) changes upon DNA hybridisation using a transistor. The developed sensor responds sensitively to TP53 mutant DNA as low as 100 nM concentration. The sensor responds linearly as a function of DNA target concentration and is able to differentiate between complementary and noncomplementary DNA target sequences.

Abstract
An accurate, rapid, and cost-effective biosensor for the quantification of disease biomarkers is vital for the development of early-diagnostic point-of-care systems. The recent discovery of the trans-cleavage property of CRISPR type V effectors makes CRISPR a potential high-accuracy bio-recognition tool. Herein, a CRISPR-Cas12a (cpf1) based electrochemical biosensor (E-CRISPR) is reported, which is more cost-effective and portable than optical-transduction-based biosensors. Through optimizing the in vitro trans-cleavage activity of Cas12a, E-CRIPSR was used to detect viral nucleic acids, including human papillomavirus 16 (HPV-16) and parvovirus B19 (PB-19), with a picomolar sensitivity. An aptamer-based E-CRISPR cascade was further designed for the detection of transforming growth factor β1 (TGF-β1) protein in clinical samples. As demonstrated, E-CRISPR could enable the development of portable, accurate, and cost-effective point-of-care diagnostic systems.

Abstract
Nowadays, analyzing circulating tumor DNA (ctDNA), a very small part of circulating free DNA (cfDNA) carried by blood, is considered to be an interesting alternative to conventional single-site tumor tissue biopsies, both to assess tumor burden and provide a more comprehensive snapshot of the time-related and spatial heterogeneity of cancer genetic/epigenetic scenery. The determination of ctDNA and/or mapping its characteristic features, including tumor-specific mutations, chromosomal aberrations, microsatellite alterations, and epigenetic changes, are minimally invasive, powerful and credible biomarkers for early diagnosis, follow-up, prediction of therapy response/resistance, relapse monitoring, and tracking the rise of new mutant subclones, leading to improved cancer outcomes This review provides an outline of advances published in the last five years in electrochemical biosensing of ctDNA and surrogate markers. It emphasizes those strategies that have been successfully applied to real clinical samples. It highlights the unique opportunities they offer to shift the focus of cancer patient management methods from actual decision making, based on clinic-pathological features, to biomarker-driven treatment strategies, based on genotypes and customized targeted therapies. Also highlighted are the unmet hurdles and future key points to guide these devices in the development of liquid biopsy cornerstone tools in routine clinical practice for the diagnosis, prognosis, and therapy response monitoring in cancer patients.

Abstract
Nature's great repository provides nucleic acids and amino acids as the fundamental elements of life. Inspired by the programmability of nucleic acids, DNA nanotechnology has been extensively developed based on the strand displacement reaction of nucleic acids. In comparison with nucleic acids, amino acids possess higher programmability and more functionalities owing to the diversity of the amino acid unit. However, the design of the peptide-based bimolecular cascade is still limited. We herein describe a peptide-based strand displacement reaction, which was granted with a specific biological function by addition of a functional domain onto the coiled-coil peptide based displacement substrate. The displacement substrate was specifically designed to response to Tau protein based on a well-established Tau inhibition sequence. We demonstrated that the kinetics of the designed displacement reaction can be dynamically tuned through blocking the toehold region to prevent migration. A nanomolar Tau detection linear range was achieved through the designed displacement reaction within a rapid turnaround time of 30 min. We also presented the capability of the peptide strand displacement based sensing system operating in real human biological samples and its excellent orthogonality on response to irrelevant biological components. We envision that this will be of especially high utility for the development of next-generation biotechnology.
