Targeted temperature control in nanopores is
greatly important in further understanding biological molecules.
Such control would extend the range of examinable
molecules and facilitate advanced analysis, including the
characterization of temperature-dependent molecule conformations.
The work presented within details well-defined
plasmonic gold bullseye and silicon nitride nanopore
membranes. The bullseye nanoantennae are designed and
optimized using simulations and theoretical calculations for
interaction with 632.8 nm laser light. Laser heating was
monitored experimentally through nanopore conductance
measurements. The precise heating of nanopores is demonstrated
while minimizing the accumulation of heat in the surrounding membrane material
