Plasma-Synthesized Copper Sensor Detects Ovarian Cancer Biomarker CA 125
1+ hour, 35+ min ago (730+ words) Optical biosensors detect biological molecules by measuring changes in light properties, such as wavelength or fluorescence intensity. These sensors provide rapid, non-destructive, and real-time analysis, making them important tools in modern medical diagnostics. While gold (Au) and silver (Ag) have…...
Programming electrochemical separations for metal recovery - Nature Water
17+ min ago (214+ words) Nature Water (2026) Cite this article Industrial wastewater contains both dissolved salts and valuable metals, yet existing technologies rarely achieve water reuse and resource recovery simultaneously. Programming electrode potential can direct the fate of dissolved ions, enabling desalination and selective metal…...
