Colorimetric Binding of Melanin Inspired Coatings

Science Center, Bent Corridor

Melanin, a widely recognized biological pigment, is a prevalent but poorly understood biomolecule. Melanin and its analogs are able to bind to metals such as lead and copper, which could lead to applications in water purification and metal detection. In the past, our lab developed metal-binding discs that were coated using catechols, one type of synthetic melanin analog. Upon binding, these discs produce a discernable color change. This poster describes our recent efforts to investigate the structure and properties of a variety of catechol-based materials, with the aim of optimizing the responsiveness and selectivity of these discs for desired metals.
