Gold nanoparticle incorporated inverse opal photonic crystal capillaries for optofluidic surface enhanced Raman spectroscopy

Functionalized AuMBA@Ag Nanoparticles as an Optical and SERS Dual Probe in a Lateral Flow Strip for the Quantitative Detection of Escherichia coli O157:H7

“…Further increases in AgNO 3 decreased the Raman enhancement. This phenomenon can be interpreted as a larger silver shell thickness damping the laser excitation of MBA and hindering the output of MBA's Raman signal (Zhao et al., ). Furthermore, a larger shell thickness will affect the coupling between the gold core and silver shell, and reduce the electromagnetic enhancement effect (D. Zhang et al., ).…”

Self-organization of gold nanoparticles on silanated surfaces

“…AuNPs have been studied intensively for a wide range of applications such as catalysis [9], biosensing [10], colorimetric sensing [11], optical sensing (surface plasmon resonance (SPR) and surface-enhanced Raman scattering (SERS)) [12–13], photonics [13–14], photovoltaic devices [15] and photothermal therapy [16]. AuNPs exhibit well-defined optical properties such as surface plasmon resonance, which depends on the size and shape of nanoparticles, interparticle distance and the effective refractive index of the surrounding medium [17].…”

Fabrication of Au- and Ag–SiO2 inverse opals having both localized surface plasmon resonance and Bragg diffraction

“…The co-assembly of templating microspheres and metallic nanoparticles can also be done with a convective assembly approach [22]. For optofluidic applications, inverse opals containing nano-voids have been prepared in a capillary tube from polystyrene and SiO 2 nanoparticles [23]. Incorporation of gold nanoparticles was obtained with in situ synthesis of nanoparticles in nano-voids.…”
