  • Raising plasmonic nanoantennas on pillars enhances their performance for sensor devices. Here, the authors show that the proximity of such pillar structures can be dynamically tuned by electron beams, offering an additional mechanical degree of freedom to alter their optical properties.

  • Recently, there has been a growing interest in do-it-yourself components to accelerate development of inexpensive fabrication approaches. Here, Chen et al.present a plasmon-assisted etching technique to fabricate planar optical components using arrays of gold pillar-supported bowtie nanoantennas as a template.

  • Plasmonic systems are a useful platform for many nanoscale applications, and plasmonic tweezers offer a method for trapping and manipulating biological particles. Roxworthy et al. study fluid convection in a nanoantenna optical trapping system and characterise the heat flow due to optical absorption.
