Micro-array based on parafilm towards the opto-analysis of Cu( ii ), Cr( vi ), and Ni( ii ) ions in fish samples by specific indicators: a state-of-the-art approach

Puntos clave

• 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
