Chemosensing Technology for Detection of Heavy Metal Ions

Advantages / Salient Technical Features
• Measure of concentration through chemosensing
principles
• Highly selective and sensitive detection of few heavy
metal ions such as Mercury ion Quick response time
(<1 min) Indigenously designed and developed and
hence customizable and can have better after sales
service support
• Optional Features · detection in visible wavelength
region
• Selectivity: Mercury ion
• Sensitivity of detection: fluorescence LOD = 0.3 nM of
ion concentration Application/Uses
• Reproducibility: Error in signal amplification with • Assessment in drinking water quality
Hg(II) (IL+Hg(II)/ IL>100 fold) : <2% Monitoring toxic effluent level in wastewater
• Reversibility: The reset of photophysical signals of Localization of bio-accumulated metal ions
these Hg(II)-probe complex could be achieved with Cyto- and Phyto- toxicological evaluation
acetate anion, repetitive signaling operation up to 10 Clinical impact assessment through imaging
cycles. Quality check on organic solvents
