AbstractSolid‐state nanopore gating inspired by biological ion channels is gaining increasing traction due to a large range of applications in biosensing and drug delivery. Integration of stimuli‐responsive molecules such as poly(N‐isopropylacrylamide) (PNIPAM) inside nanopores can enable temperature‐dependent gating, which so far has only been demonstrated using external heaters. In this work, plasmonic resonators are combined inside the nanopore architecture with PNIPAM to enable optical gating of individual or multiple nanopores with micrometer resolution and a switching speed of a few milliseconds by thermo‐plasmonics effects. A temperature change of 40 kelvin per millisecond is achieved and demonstrates the efficacy of this method using nanopore ionic conductivity measurements that enable selective activation of individual nanopores in an array. Moreover, the selective gating of specific nanopores in an array can set distinct ionic conductance levels: low, medium, and high (i.e., “0,” “1,” and “2”), which can be exploited for logical gating with optical signal control. Such selective optical gating in nanopore arrays marks a breakthrough in nanofluidics, as it paves the way toward smart devices that offer multifunctional applications including biosensing, targeted drug delivery, and fluidic mixing.
