Colorimetric sensor array: Rapid and sensitive approach for detecting and identifying emerging nanomaterial contaminants
Emerging contaminants such as nanomaterials and micro-plastics pose significant environmental risks due to their elusive nature and the limitations of current detection methods. Conventional techniques like UV-Vis spectroscopy and electron microscopy, though effective, are costly, low-throughput, and non-portable, particularly impacting populations in remote areas and less developed countries with increased vulnerability to materials contamination in natural and drinking water.
