Pazopanib (PZB) is a multiple kinase inhibitor used for the treatment of advanced renal cell carcinoma and soft tissue sarcoma. This work focuses on achieving high selectivity and sensitivity for the determination of PZB using a molecularly-imprinted polymer (MIP)-based electrochemical sensor. The MIP-based sensor was fabricated by thermal polymerization directly on a glassy carbon electrode (GCE). The electrochemical response of the 4-ABA/PZB@MIP/GCE sensor was investigated using differential pulse voltammetry. The characterization of the sensor in terms of morphology and electrochemistry was performed using scanning electron microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. The 4-ABA/PZB@MIP/GCE sensor exhibited a linear response ranging from 1.0 × 10–13 M to 1.0 × 10–12 M with a limit of detection and limit of quantification of 1.04 × 10–14 M and 3.48 × 10–14 M, respectively. The applicability of the sensor was evaluated by determining commercial samples of human serum and tablets, and good recoveries were obtained. The results showed that the sensor could identify PZB, compared to structurally analogous drugs such as axitinib, nilotinib, and erlotinib. The interfering substances commonly found in biological fluids were investigated. Finally, the sensor design was validated using a non-imprinted polymer-based GCE.

Endocrine-disrupting chemicals (EDCs) are synthetic compounds widely used in various industrial and consumer products, raising concerns about their potential adverse effects on human health and the environment. Among the numerous EDCs, Bisphenols, phthalates, and per- and poly-fluoroalkyl substances (PFAS) have attracted significant attention due to their prevalence and adverse effects. Accurately identifying and quantifying these EDCs is important for assessing exposure levels and evaluating the associated risks. This review article shed the light on recent advancements in modified electrochemical sensors and biosensors using nanomaterials, molecularly imprinted polymers (MIPs), Metal organic frameworks and nanocomposite-based electrodes, and their applicability for detecting EDCs during the past five years. The development of innovative electrode materials, optimization strategies used to increase the sensitivity and selectivity of electrochemical sensors. The challenges of real-world sample analysis are investigated as well along with possible solutions, such as matrix interference and detection limitations. Future perspectives and emerging trends in the electrochemical detection of EDCs, are also elaborated with a particular emphasis on developments in portable and miniaturized devices, multiplexed sensing platforms, and the incorporation of machine learning and artificial intelligence for better data analysis, and on-site detection.
