Capillary-force-induced collapse lithography for controlled plasmonic nanogap structures

Capillary force lithography for cardiac tissue engineering.

Cardiovascular disease remains the leading cause of death worldwide(1). Cardiac tissue engineering holds much promise to deliver groundbreaking medical discoveries with the aims of developing functional tissues for cardiac regeneration as well as in vitro screening assays. However, the ability to create high-fidelity models of heart tissue has proven difficult. The heart's extracellular matrix ...

Nanogap structures for molecular nanoelectronics

This study is focused on the realization of nanodevices for nano and molecular electronics, based on molecular interactions in a metal-molecule-metal (M-M-M) structure. In an M-M-M system, the electronic function is a property of the structure and can be characterized through I/V measurements. The contact between the metals and the molecule was obtained by gold nanogaps (with a dimension of les...

Plasmonic structures fabricated via nanomasking sub-10 nm lithography technique

Making use of a newly established nanomasking technique, nanoscale features (sub-10 nm) have been fabricated with the potential to act as plasmonic enhancement structures. The technique makes use of a two-step lithography process to simultaneously produce many plasmonic hotspots with two-dimensional features over a large area, showing promise for mass production scalability. This technique is h...

Metal Particle-Surface System for Plasmonic Lithography

Optical rectification and field enhancement in a plasmonic nanogap.

Metal nanostructures act as powerful optical antennas because collective modes of the electron fluid in the metal are excited when light strikes the surface of the nanostructure. These excitations, known as plasmons, can have evanescent electromagnetic fields that are orders of magnitude larger than the incident electromagnetic field. The largest field enhancements often occur in nanogaps betwe...
