Abstract
Diamino polyacetate benzene compounds are used as a selective fluorescence probe, sensor, or binders for divalent metal ions. The compounds provide for uses as divalent metal ion sensors in diagnostic applications and binders for environmental and medical treatments.
Claims20
A method for the detection of a metal ion in a sample using a diamino polyacetate benzene compound as a metal ion sensor, comprising the steps of:
- a. incubating a sample containing the metal ion for a sufficient time to complex the metal ion with a diamino polyacetate benzene compound;
- b. exciting the complex with a wavelength capable of causing emission of a fluorescent signal by the diamino polyacetate benzene compound/metal ion complex;
- and
- c. detecting the fluorescent signal emitted by the complex.
A sensor used for the detection of a metal ion comprising a diamino polyacetate benzene compound that emits a fluorescent signal after binding to the metal ion.
A composition for removal of a metal ion from an environmental or biological fluid comprising a diamino polyacetate benzene compound that binds to the metal ion so that the bound metal ion and compound can be removed from the fluid.
