Breakthrough in Malaria Detection: Researchers Develop Dual-Mode Biosensor

Strategic Insights -

Researchers at Saveetha Engineering College have made a significant breakthrough in malaria detection by developing a metasurface biosensor that can simultaneously detect cancer and malaria biomarkers. This innovative device operates at frequencies between 0.189-0.423 THz and demonstrates exceptional sensitivity for both cancer and malaria detection. The sensor's robust performance characteristics and machine learning optimization using Random Forest Regression have achieved R2 scores of up to 94% for refractive index predictions and 89% for incident angle variations, validating its reliability and predictive accuracy.
