Accessing both electrochemical SEIRA and SERS with ultrasensitive metamaterials for enhanced molecular identification
Nicolas Spiesshofer, Tabitha Jones, Sarah May Sibug Torres +11
Surface-enhanced IR absorption (SEIRA) and surface-enhanced Raman spectroscopy (SERS) are complementary techniques that allow for ultrasensitive chemical fingerprinting. Non-invasi…

Migration of gold atoms into a thiol-bonded molecular self-assembled monolayer, forming a cluster exhibiting a Coulomb staircase
Bingxin Li, Shanglong Ning, Chunyang Miao +16
Thiol-based self-assembled monolayers (SAMs) on gold surfaces are one of the fundamental building blocks of molecular electronics. The strong chemical affinity of the gold and sulf…

Tracking and controlling monolayer water in gold nanogaps using extreme plasmonic spectroscopy
Elle W. Wyatt, Sarah May Sibug-Torres, Rakesh Arul +5
Nanogaps are ubiquitous across science, confining molecules and thus changing chemistries which influence many areas such as catalysis, corrosion, photochemistry, and sensing. Howe…
