Abstract:
1. A method of detecting melamine in a test sample, comprising: combining the test sample with a melamine aggregation inducing agent and a plurality of particles in an aqueous media, wherein the particles have an average diameter of between 1 and 2500 nm; mixing the test sample, the aggregation inducing agent, and the particles to allow melamine in the test sample to interact with the aggregation inducing agent and the particles to produce a change in visual color and a change in turbidity; monitoring the media to observe the change in visual color and the change in turbidity; correlating the change in turbidity of the media with the presence of melamine in the test sample; and correlating the change in visual color of the media with a concentration of melamine in the test sample.
