Electrochemical biosensors for hepatocellular carcinoma

The current review analyzes progress in electrochemical detection techniques for hepatocellular carcinoma biosignatures, highlighting their potential to enhance the timely detection and management of hepatocellular carcinoma. In this study, the authors explore the present state of hepatocellular carcinoma biosignatures, encompassing conventional proteins such as alpha-fetoprotein and promising biosignatures like non-coding RNAs and circulatory tumor DNA (ctDNA). This text analyzes the principles of electrochemical biosensing and explores sophisticated sensor designs employing surface modification techniques, innovative recognition elements, and nanomaterials. Particular focus is directed towards aptamer-based sensors, microfluidic technologies, and label-free methodologies. Herein, recent advancements in enhancing sensitivity and specificity are discussed, with some platforms reaching a threshold at the femtogram scale. The discussion also encompasses the progress achieved in point-of-care applications and the obstacles faced in transitioning experimental paradigms to medical applications. The prospective influence of these methodologies on medical results is under evaluation, emphasizing early detection and tailored treatment approaches. Future research should focus on creating advanced, integrated detection systems and conducting comprehensive clinical validation studies to assess the real-world effectiveness of electrochemical biosensors.
