Equipment-free and visual detection of Pb2+ ion based on curcumin-modified bacterial cellulose nanofiber

Elham Sheikhzadeh et al.

Summary: This study developed a novel colorimetric sensor based on curcumin embedded in bacterial cellulose nanofiber for the determination of lead ions in rice. The sensor exhibited a color change from orange to red in the presence of Pb2+, showing selectivity and detection limits of 9 μM and 0.9 μM through naked eye observation and image processing. The sensor has potential for low-cost and portable on-site monitoring of Pb2+ ions.
