Abstract: A method of detecting a substance, wherein the method includes functionalizing a plurality of sensors, wherein the functionalizing the plurality of sensors comprises depositing a first material using a piezoelectrically actuated pipette system, wherein the first material includes a polymer, a receptor, and a solvent, wherein the solvent comprises dimethylformamide. The method further includes evaporating a solution of the first material, wherein a residue after the evaporation comprises a functionalized chemical. Additionally, the method includes introducing a control material to a first set of sensors of the plurality of sensors using the piezoelectrically actuated pipette system. Further, the method includes introducing a test material to a second set of sensors of the plurality of sensors using the piezoelectrically actuated pipette system, wherein the test material comprises an analyte. Moreover the method includes determining a difference between a first resonant frequency shift in the first set of sensors of the plurality of sensors and a second resonant frequency shift in the second set of sensors of the plurality of sensors.

Abstract: Three-dimensional (3D) printed fluoropolymer-based energetic compositions are made using 3D printing methods. The 3D printed fluoropolymer-based energetic compositions comprise a fluoropolymer and a reactive metal or metal oxide. The total weight percentage of the fluoropolymer and the reactive metal or metal oxide is 70-100% of the 3D printed fluoropolymer-based energetic composition, and the weight percentage of the reactive metal or metal oxide is 5-85 wt % of the total weight of the 3D printed fluoropolymer-based energetic material. The 3D printed fluoropolymer-based energetic material has a thickness of at least 200 μm.
