An OFF-ON fluorescence sensor for Cd2+ detection was developed and validated in spiked milk and seawater matrices. The paper is primarily a sensor development study; no unspiked occurrence measurements of Cd in milk or seawater are reported. The milk matrix validation demonstrates applicability for food safety screening.
Key numbers
- Specific LOD, linear range, and recovery data in milk matrix in full paper.
- No occurrence data for Cd in milk; all matrix tests use spiked samples.
Methods (brief)
OFF-ON fluorescence mechanism; specific probe chemistry not confirmed at classification stage. Measures total Cd2+. No speciation. Recovery experiments in spiked milk and seawater.
Implications
Certification: Method development. No food concentration data to contribute to Cd contamination profiles. Courses: Example of fluorescence-based sensor validation in dairy matrix.
