Abstract: The present disclosure features an apparatus for identifying molecules, the apparatus including chambers configured to receive a conducting media; a membrane including a pore separating the chambers, a first set of electrodes in the chambers, a first current detector measuring an electrical signal between the first set of electrodes, a second set of electrodes electrically contacting the membrane, a second current detector configured measuring an electrical signal between the second set of electrodes, a plasmonic feature adjacent to the pore of the membrane, a light source configured to emit light onto the plasmonic feature, a light collector to collect the light scattered from the plasmonic feature, and a computing device configured to identify at least one attribute of a molecule that passes through the pore of the membrane.

Abstract: A method of creating crumples in a monolayer entails contacting a monolayer comprising a two-dimensional material with a thermally contractible polymer, and heating the thermally contractible polymer to contract the polymer and induce buckling of the monolayer, where a plurality of crumples are formed in the monolayer due to the buckling. A device having a crumpled microstructure includes a monolayer comprising a two-dimensional material and including a plurality of crumples.
