Abstract
The present invention provides a chemiluminescent ink formulation, comprising: a phthalocyanine metal catalyst; a visible dye; and a solvent. The formulation is useful in catalyzing a chemiluminescent reaction, by admixing for example, luminol or isoluminol with an oxidizing agent, a base and the chemiluminescent ink formulation to emit light.
Claims18
A chemiluminescent ink formulation adsorbed to a membrane, the chemiluminescent ink formulation comprising:
- a phthalocyanine metal catalyst, wherein the metal is a member selected from the group consisting of Ni, Mn, Fe, Co, and Ru;
- a visible dye, other than the phthalocyanine metal catalyst;
- and
- a solvent, wherein the formulation is adsorbed to the membrane which membrane is a member selected from the group consisting of nitrocellulose, PVDF, and nylon.
A method for catalyzing a chemiluminescent reaction with a chemiluminescent ink formulation absorbed to a membrane, said method comprising:
- Admixing luminol, isoluminol or luminol derivative with an oxidizing agent, a base and the chemiluminescent ink formulation absorbed to the membrane, wherein the chemiluminescent ink formulation comprises:
- A phthalocyanine metal catalyst, wherein the metal is a member selected from the group consisting of Ni, Mn, Fe, Co, and Ru;
- a visible dye, other than the phthalocyanine metal catalyst;
- and
- a solvent, and wherein the membrane is a member selected from the group consisting of nitrocellulose, PVDF, and nylon, to catalyze a chemiluminescent reaction and emit light.
A chemiluminescence reaction method with a chemiluminescent ink formulation adsorbed to a membrane, said method comprising:
- (i) contacting chemilumine scent ink formulation adsorbed to the membrane, wherein the chemiluminescent ink formulation comprises:
- a phthalocyanine metal catalyst, wherein the metal is a member selected from the group consisting of Ni, Mn, Fe, Co, and Ru;
- a visible dye, other than the phthalocyanine metal catalyst;
- and
- a solvent, wherein the membrane is a member selected from the group consisting of nitrocellulose, PVDF, and nylon, with a reaction mixture comprising luminol, isoluminol or a luminol derivative, an oxidant and a base to emit light;
- (ii) detecting the emitted light;
- and
- (iii) optionally correlating the emitted light to the concentration of luminol or isoluminol.
