SUPERHYDROPHOBIC PLATFORM FOR SENSING URINE METABOLITES AND TOXINS

WIPO Patent Application WO/2019/139543

A1

Disclosed herein is a composite superhydrophobic material comprising: a substrate layer comprising a set of positively or negatively charged functional groups; a metal nanoparticle coating on top of the substrate layer, wherein said metal nanoparticle coating comprises metal nanoparticles of different shape and/or size that have negatively or positively charged functional groups; a metal layer on top of the metal nanoparticle coating; and a first superhydrophobic layer on top of the metal layer. Also disclosed herein is a method of making said material, and a method of predicting increased risk of spontaneous miscarriage using said material.
