Development of Lateral Flow Assay for Melamine Detection Based on Colloidal Gold

A method for rapid detection of melamine by colloidal gold strip was introduced.Four steps were involved in the process of preparing the strip,including production of colloidal gold,manufacture of immunogold,installation and analysis of the strip.With the strip,10 g/L of melamine was detected in less than 10 min.Fresh milk could be detected directly without pretreatment,so it provided a simple,accurate and rapid method for on-site testing of melamine.
