|a Thiol functionalized magnetic silica-core shell (MPTES-Fe3O4@SiO2) is used in the colorimetric sensor for the recognition of silver ions. This detected system acts more sensitive and selectively for silver ions in real-time applications. Thiol functionalized core-shell magnetic nanoparticles interact with silver ions to form a metal-thiol complex with the appearance of yellow color in the solution with surface resonance peak (403cm-1) in UV spectra. This colorimetric sensor is very cheap, and facile in the detection of a silver ion with the lower limit of the detection value of 10 nm. Furthermore, we have applied for the monitoring of the real samples of this sensing system with good recovery results. © This work is licensed under a CC BY 4.0 license.
