Colorectal cancer (CRC) is known as one of the most common types of cancer in the world, and its early detection plays a decisive role in the success of treatment and preventing the spread of tumors in the body. Early detection is usually done through the identification of biomarkers, and the use of new sensing technologies can significantly improve the detection process. In recent years, the development and application of various biosensors, including electrical, optical, mechanical, and electrochemical sensors, for CRC detection has attracted considerable attention from researchers. Among them, electrochemical biosensors are considered a very suitable option for CRC detection due to their features such as short detection time, high sensitivity, and the ability to detect very small amounts of biomarkers. In general, combining these sensors with various nanostructures can significantly increase their sensitivity and stability. Among these nanomaterials, graphene and its derivatives, including graphene oxide (GO), reduced graphene oxide (rGO), and graphene quantum dots (GQDs), have attracted significant attention due to their unique electrical properties, high specific surface area, excellent conductivity, and superior mechanical properties, making them ideal candidates for the fabrication of electrochemical biosensors. This review focuses on graphene-based electrochemical biosensors for CRC detection over the past five years, analyzing key biomarkers such as carcinoembryonic antigen (CEA), carbohydrate antigen 19–9 (CA 19–9), and microRNAs (miRNAs), which are commonly used for CRC diagnosis. In addition, indicators such as the linear performance range (LR), typically ranging from nanomolar (nM) to micromolar (μM), and the limit of detection (LOD), ranging from femtomolar (fM) to nanomolar (nM) concentrations, have been discussed. Finally, alongside outlining the challenges associated with the development of this category of biosensors, future prospects and strategies aimed at enhancing efficiency, selectivity, reproducibility, and broadening the clinical applications of graphene-based electrochemical biosensors have also been discussed. Overall, this study demonstrates that combining graphene with advanced sensing technologies could pave the way for the development of rapid, accurate, and reliable diagnostic tools, contributing to significant progress in the early detection of CRC. • Overview of current biosensor technologies applied for colorectal cancer detection. • Focus on recent advances in graphene-based electrochemical biosensors. • Graphene nanostructures enhance sensitivity, conductivity, and biomarker detection. • Comparison of graphene-derived materials for CRC-related biomarker sensing. • Identification of challenges, limitations, and future directions for clinical translation.

Organic micropollutants such as antibiotics and dyes persist in water and are often poorly removed by conventional treatment. Semiconductor-based photocatalysis provides an efficient visible-light-driven route to degrade these contaminants. Herein, a novel copper oxide (CuO)/polypyrrole (PPy)/reduced graphene oxide (rGO) composite was synthesized via a simple hydrothermal method. The physicochemical properties of the as-prepared photocatalysts were characterized using XRD, XPS, Raman, FESEM-EDX, UV–vis, BET, PL analyses. Moreover, the photocatalytic activity was evaluated by the degradation of tetracycline (TC) and methyl orange (MO) under visible light for 240 min. The CuO/PPy/rGO ternary composite exhibited markedly higher photocatalytic performance than bare CuO and CuO/PPy, achieving 99% degradation of TC and 60% degradation of MO. Notably, the improved performance is attributed to rGO incorporation, which likely forms a conductive, high-surface-area structure that promotes charge separation and interfacial electron transport. Kinetic analysis showed a higher pseudo-first-order rate constant for TC degradation over the ternary composite (kapp = 0.010 min −1 ) than bare CuO (0.003 min −1 ), confirming the superior activity of the ternary catalyst. Additionally, HPLC analysis was employed to further confirm the degradation efficiency of TC and MO. The catalyst also retained high activity over five cycles, and radical-trapping experiments identified •O 2 − as the dominant reactive species. Overall, the CuO/PPy/rGO composite offers a durable and efficient visible-light photocatalyst for sustainable wastewater treatment. • CuO/PPy composite was anchored onto rGO using a hydrothermal synthesis method. • The degradation efficiency of pollutants was enhanced by CuO/PPy/rGO composite. • CuO/PPy/rGO composite exhibited high reusability for photocatalytic applications.
