Abstract
Herein, a simple and highly sensitive electrochemical sandwich-like immunosensor for the squamous cell carcinoma antigen (SCCA) was constructed using gold nanoparticle/graphene nanosheet (Au/GN) nanohybrids as a sensing platform and β-cyclodextrin/Ti3C2Tx MXenes (β-CD/Ti3C2Tx) as a signal amplifier. The good biocompatibility and large surface area as well as the high conductivity of Au/GN allow the platform to load primary antibodies (Ab1) and facilitate electron transport. In the case of the β-CD/Ti3C2Tx nanohybrids, the β-CD molecule is dedicated to binding secondary antibodies (Ab2) through host-guest interactions, thus inducing the formation of the sandwich-like structure Ab2-β-CD/Ti3C2Tx/SCCA/Ab1/Au/GN in the presence of SCCA. Interestingly, Cu2+ can be adsorbed and self-reduced on the surface of the sandwich-like structure to form Cu0 since Ti3C2Tx MXenes can exhibit superior adsorption and reduction capabilities towards Cu2+, and a prominent current signal of Cu0 can be observed via differential pulse voltammetry. Based on this principle, an innovative signal amplification strategy has been proposed for SCCA detection, which avoids the process of labeling the probe and the specific immobilization step of catalytic components on the surface of amplification markers. After the optimization of various conditions, a wide linear range from 0.05 pg mL-1 to 20.0 ng mL-1, coupled with a low detection limit of 0.01 pg mL-1, was obtained for SCCA analysis. The proposed method for SCCA detection was also applied in real human serum samples and the observed results are satisfactory. This work opens up new pathways for constructing electrochemical sandwich-like immunosensors for SCCA and other targets.

Mikrochim Acta 2023; 190:92.

Abstract
The incidence rate of cardiovascular diseases (CVDs) remains high, and their mortality rate is significantly higher than that of other diseases. Growth differentiation factor-15 (GDF-15) is a recently developed biomarker for the early diagnosis and prognostic evaluation of CVDs because its concentration in serum increases substantially after a cardiovascular injury or an inflammatory reaction. In this study, a sandwich-type immunosensor was constructed for the sensitive detection of GDF-15. Specifically, peony-like zinc gallinate (ZnGa2O4) prepared using a hydrothermal method, which exhibits excellent electrocatalytic performance, was coupled with Au nanoparticles (NPs) to obtain golden-peony-like ZnGa2O4/Au NPs. They preserved the immune activity of GDF-15 antibody molecules and further enhanced the conductivity, thereby realizing additional signal amplification. Hollow polyaniline (PANI) microtubules decorated with Pd NPs were used as the sensing platform (PANI/Pd NPs). The hollow microtubules provided abundant active sites and considerably improved the electron-transfer rate. Under optimal conditions, a linear range and remarkably low detection limit of 100 fg mL-1-10 ng mL-1 and 42.23 fg mL-1, respectively, were achieved. These experimental results indicate that the strategy reported herein can be adopted as a novel approach for the convenient and rapid detection of GDF-15.

Abstract
Neuron-specific enolase (NSE) is a specific marker for small cell carcinoma (SCLC). Sandwich-type electrochemical immunosensors are powerful for biomarker analysis, and the electrocatalytic activity of the signal amplification platform and the performance of the substrate are critical to their sensitivity. In this work, N atom-doped graphene functionalized with hollow porous Pt-skin Ag-Pt alloy (HP-Ag/Pt/NGR) was designed as a dual signal amplifier. The hollow porous Pt skin structure improves the atomic utilization and the larger internal cavity spacing significantly increases the number of electroactive centers, thus exhibiting more extraordinary electrocatalytic activity and durability for H2O2 reduction. Using NGR with good catalytic activity as the support material of HP-Ag/Pt, the double amplification of the current signal is realized. For the substrate, polypyrrole-poly(3,4-ethylenedioxythiophene) (PPy-PEDOT) nanotubes were synthesized by a novel chemical polymerization route, which effectively increased the interfacial electron transfer rate. By coupling Au nanoparticles (Au NPs) with PPy-PEDOT, the immune activity of biomolecules is maintained and the conductivity is further enhanced. Under optimal conditions, the linear range was 50 fg mL-1 - 100 ng mL-1, and the limit of detection (LOD) was 18.5 fg mL-1. The results confirm that the developed immunosensor has great promise for the early clinical diagnosis of SCLC.

Abstract
Cerium oxide nanozymes have emerged as a new type of bio-antioxidants in recent years. CeO2 nanozymes possess enzyme mimetic activities with outstanding free radical scavenging activity, facile synthesis conditions, and excellent biocompatibility. Based on these extraordinary properties, use of CeO2 nanozymes has been demonstrated to be a highly versatile therapeutic method for many diseases, such as for inflammation, rheumatoid arthritis, hepatic ischemia-reperfusion injury and Alzheimer's disease. In addition to that, CeO2 nanozymes have been widely used in the diagnosis and treatment of cancer. Many examples can be found in the literature, such as magnetic resonance detection, tumour marker detection, chemotherapy, radiotherapy, photodynamic therapy (PDT), and photothermal therapy (PTT). This review systematically summarises the latest applications of CeO2-based nanozymes in cancer research and treatment. We believe that this paper will help develop value-added CeO2 nanozymes, offering great potential in the biotechnology industry and with great significance for the diagnosis and treatment of a wide range of malignancies.

Abstract
Developing a highly sensitive immunoassay for tumor biomarkers is particularly important in bioanalysis and early disease diagnosis. In this work, a simple one-pot solvothermal method was developed for controllable synthesis of well-dispersed PtCo alloyed nanodendrites (PtCo NDs) by using l-carnosine as the co-structure-directing agent. The PtCo NDs had a large specific surface area and provided abundant active sites available for electrocatalytic oxygen reduction reaction (ORR). Based on the highly enhanced currents of the ORR, a novel label-free electrochemical immunosensor was fabricated for highly sensitive assay of carbohydrate antigen 15-3 (CA15-3). The sensor showed a wide linear range of 0.1-200 U mL-1 and a low limit of detection (LOD) down to 0.0114 U mL-1 (S/N = 3), in turn exploring its application to diluted human serum samples with satisfactory results. This study provides a feasible platform for monitoring other tumor markers in clinical diagnosis.
