The aim is to develop a cost-effective sensor for identifying Cu, Cr, and Ni ions in fish samples.
Introduced parafilm-based colorimetric micro-array as a sensor
Targeted detection of specific metal ions: Cu(ii), Cr(vi), Ni(ii)
Applied the method to real fish samples.
Successfully detected Cu(ii), Cr(vi), and Ni(ii) ions in fish samples
Demonstrated effectiveness of the parafilm micro-array as a sensing technology
Provided a low-cost solution for environmental monitoring.

Resumen

In this study, a parafilm-based colorimetric micro-array (PCMA) is introduced as a novel, low-cost sensor for the specific detection of copper (Cu( ii )), chromium (Cr( vi )), and nickel (Ni( ii )) ions in real samples.
