METHODS FOR BINDING AND PRECIPITATING GOLD USING MICROBIAL-DERIVED METALLOPHORES AND THEIR USES

摘要

The present application discloses metallophores that complex soluble gold and generate solid gold forms, including gold nanoparticles. In an embodiment, the metallophores are microbial metabolites isolated from organisms that are resistant to gold, or are analogs thereof. Methods of using the metallophores to extract and detect gold, along with detectors comprising the metallophores are disclosed.

主权项

1. A method of removing soluble gold in a sample comprising:
(a) contacting the sample with a metallophore under conditions to form a complex between the soluble gold and the metallophore and conversion of the soluble gold into solid gold; and (b) isolating the solid gold from the sample,wherein the metallophore is microbial metabolite comprising a chelation core that binds to gold ions and wherein the metabolite converts the soluble gold ions to solid gold (Au0).
