Graphene–Copper Hybrid Terahertz Biosensor with KNN Sensitivity Optimization for Early Skin Cancer (Melanoma) Detection

Key Points

• The biosensor demonstrates significant improvement in sensitivity for early melanoma detection.
• Sensitivity was optimized using the K-nearest neighbors (KNN) algorithm, achieving a notable increase.
• Assessment involved comparing performance metrics of the hybrid sensor against traditional methods.
• Results indicate potential for early skin cancer diagnosis, but further validation in clinical settings is necessary.
