Schematics of a a widespread of bacteria pathogens by human hand contacts; b a desired attachment of bacteria to a solid surface of capture platform by a pathogen to 3D nanostructural attachments; c PUN and f 3D HPN films. SEM images of d, e PUN and g, h 3D HPN films. Raman spectra and maps of i PUN and j 3D HPN films. Polyurethane and polyaniline were denoted as PU and PANI, respectively. k Photographs of a large-area 3D HPN film and its practical applications as attachments to a smartphone, ceramic cup, and pen. Scale bar: 1 μm
