Electrochemical nanosensors for early detection of childhood cancer.

Early detection of childhood cancer is crucial for improving treatment outcomes. Identifying biomarkers for pediatric cancers is a critical step in cancer early detection and successful treatment. Biosensors are advanced analytical tools to identify cancer-related biomarkers with high sensitivity and specificity. Nanomaterials play a transformative role in the development of biosensors, enhancing their sensitivity, specificity, and overall performance. Nanomaterial based electrochemical sensors and biosensors as a cutting-edge frontier in analytical chemistry have enormous potential for detecting pediatric cancer biomarkers. By detecting biomarkers like proteins, DNA mutations, or metabolites associated with cancer, nano electrochemical biosensors offer a non-invasive, rapid, and affordable technique for early diagnosis, and disease monitoring.
