Pyrrole-modified gold nanoparticle structure for dual UV-vis and smartphone-based colorimetric detection of hexavalent chromium in food and environmental samples

As a potent, human-carcinogenic toxin, hexavalent chromium, Cr(vi), causes aggressive cancers and severe organ failure. It poses a major environmental threat due to its mobility in water and easy cellular penetration. Therefore, sensitive detection methods are essential for monitoring and managing Cr(vi) levels in food...
