Gold nanorods (NRs), pseudo-one-dimensional rod-shaped nanoparticles (NPs), have
become one of the burgeoning materials in the recent years due to their anisotropic shape …

Single-molecule detection has long relied on fluorescent labeling with high quantum-yield
fluorophores. Plasmon-enhanced detection circumvents the need for labeling by allowing …

Assembling metamolecules from anisotropic, shape-engineered nanocrystals provides the
opportunity to orchestrate distinct optical responses one nanocrystal at a time. The Au …

The change in refractive index around plasmonic nanoparticles upon binding to
biomolecules is routinely used in localized surface plasmon resonance (LSPR)-based …

Colloidal noble metal nanoparticles (NPs) are composed of metal cores and organic or
inorganic ligand shells. These NPs support size‐and shape‐dependent plasmonic …

Ultrafast laser irradiation can induce morphological and structural changes in plasmonic
nanoparticles. Gold nanorods (Au NRs), in particular, can be welded together upon …

The ability to control interparticle forces not only improves the existing nanoparticle (NP)
functionalities but paves the way for newer properties as well. A proof of concept in this …

For noble metals, such as gold (Au) and silver (Ag), it is well-known that surface plasmons of
their nanocrystals have significant spatial confinement and propagation loss due to the …

The mechanical properties and stability of metal nanoparticle colloids under high-pressure
conditions are investigated by means of optical extinction spectroscopy and small-angle X …

This work describes the interaction between femtosecond laser pulses (∼ 130 fs, 800 nm)
and gold nanorods (NRs) leading to reshaping of the NRs. We focus on the investigation of …
