Plasmonic Nanopores for Single-Molecule Detection and Manipulation: Toward Sequencing Applications

Nano Lett. 2019 Nov 13;19(11):7553-7562. doi: 10.1021/acs.nanolett.9b02759. Epub 2019 Oct 14.

Abstract

Solid-state nanopore-based sensors are promising platforms for next-generation sequencing technologies, featuring label-free single-molecule sensitivity, rapid detection, and low-cost manufacturing. In recent years, solid-state nanopores have been explored due to their miscellaneous fabrication methods and their use in a wide range of sensing applications. Here, we highlight a novel family of solid-state nanopores which have recently appeared, namely plasmonic nanopores. The use of plasmonic nanopores to engineer electromagnetic fields around a nanopore sensor allows for enhanced optical spectroscopies, local control over temperature, thermophoresis of molecules and ions to/from the sensor, and trapping of entities. This Mini Review offers a comprehensive understanding of the current state-of-the-art plasmonic nanopores for single-molecule detection and biomolecular sequencing applications and discusses the latest advances and future perspectives on plasmonic nanopore-based technologies.

Keywords: Plasmonics; nanopore; sequencing; single-molecule; solid-state.
