Abstract: A low temperature sinterable copper nanoparticle or nanowire, comprising gold, zinc, nickel, tin, or aluminum as an alloying metal, and a capping agent. The nanoparticles or nanowires may be deposited on porous or fibrous substrates, the capping agent desorbed, and sintered at low temperature to form conductive traces or sensing elements. The nanoparticles or nanowires may be deposited by aerosol jet, inkjet or dispenser printers, for example.

Abstract: Air sampling sensor and system for detecting volatile organic compounds and applications thereof. A nanoparticle-structured chemiresistive sensor array in the analyzer generates an output signal based on the presence of selected volatile organic compounds in an air sample. The sensors of the array include sensing films from the group of molecularly-linked gold nanoparticles with different linking and capping molecules and gold nanoparticles of different sizes. A micro-processing unit analyzes the output signal of the sensor array and indicates the presence or absence of selected volatile organic compounds. The air sampling system can be used to analyze human breath and report the presence of volatile organic compounds relevant to lung cancer biomarkers. The air sampling system can also be used as an environmental air monitoring system to detect the presence of hazardous chemicals in the air.

Abstract: Nanoparticle-fibrous membrane composites are provided as tunable interfacial scaffolds for flexible chemical sensors and biosensors by assembling gold nanoparticles (Au NPs) in a fibrous membrane. The gold nanoparticles are functionalized with organic, polymeric and/or biological molecules. The fibrous membranes may include different filter papers, with one example featuring a multilayered fibrous membrane consisting of a cellulose nanofiber (CN) top layer, an electrospun polyacrylonitrile (PAN) nanofibrous midlayer (or alternate material), and a nonwoven polyethylene terephthalate (PET) fibrous support layer, with the nanoparticles provided on the fibrous membranes through interparticle molecular/polymeric linkages and nanoparticle-nanofibrous interactions. Molecular linkers may be employed to tune hydrogen bonding and electrostatic and/or hydrophobic/hydrophilic interactions to provide sensor specificity to gases or liquids. The sensors act as chemiresistor-type sensors. A preferred implementation is a sweat sensor.

Abstract: Nanoparticles with a bimetallic silver-copper (AgCu) alloy composition with ambient (room temperature) sintering properties. The bimetallic alloy is formulated with nanoparticles which are contained in a stable nanoink or nanopaste. The nanoink or nanopaste can be printed on paper and other substrates and be sintered under room temperatures. A method of creating the AgCu composition is also provided.
