Latest Patents

Shan Yan's latest patents include the development of an air-stable conductive ink. This innovative material is a low-temperature sinterable copper nanoparticle or nanowire, which incorporates gold, zinc, nickel, tin, or aluminum as an alloying metal, along with a capping agent. The unique properties of this conductive ink allow for the deposition of nanoparticles or nanowires on porous or fibrous substrates. The capping agent can be desorbed, enabling sintering at low temperatures to create conductive traces or sensing elements. The deposition methods for these nanoparticles or nanowires include aerosol jet, inkjet, or dispenser printers.

Another significant patent is the nanoparticle sensor featuring a nanofibrous membrane scaffold. This invention provides nanoparticle-fibrous membrane composites that serve as tunable interfacial scaffolds for flexible chemical sensors and biosensors. By assembling gold nanoparticles (Au NPs) within a fibrous membrane, these sensors can be functionalized with organic, polymeric, and/or biological molecules. The fibrous membranes can consist of various filter papers, including a multilayered fibrous membrane with a cellulose nanofiber (CN) top layer, an electrospun polyacrylonitrile (PAN) midlayer, and a nonwoven polyethylene terephthalate (PET) support layer. The nanoparticles are integrated into the fibrous membranes through interparticle molecular/polymeric linkages and nanoparticle-nanofibrous interactions, allowing for enhanced sensor specificity to gases or liquids. A preferred application of this technology is in sweat sensors.
