Highly organized supercrystals of Au nanorods with plasmonic antennae enhancement electrical field have made possible fast direct detection prions in complex biological media such as serum and blood. The nearly perfect three-dimensional organization render these systems excellent surface enhanced Raman scattering spectroscopy substrates uniform electric enhancement, leading to reproducibly high factor the desirable spectral range.
Development of multifunctional drug delivery vehicles with therapeutic and imaging capabilities as well in situ methods monitoring intracellular processes will greatly benefit from a simple method preparation plasmonic Au structures nanometer scale gaps between sharp metallic elements where the so-called SERS hot spots can be formed. Here synthesis gold lace capsules average diameters ca. 100 nm made network branches 3−5 wide separated by 1−3 is reported. Biocompatible amphiphilic...
We describe the design and fabrication of composite agarose gels, highly loaded with silver nanoparticles. Because gel can collapse upon drying recover when rehydrated, it be foreseen as an excellent mechanical molecular trap that additionally gives rise to dynamic hot spots network volume decreases particles get close each other, thereby generating high electromagnetic fields are needed for ultradetection. Additionally, nanoparticles physically trapped inside polymer network, analytes...
We report the formation of gold nanoparticles with a novel and useful morphology, comprising nanowires fully covered sharp tips (thorned nanowires). The synthesis is based on seeded-growth approach rapid overgrowth ultrathin wires in N,N-dimethylformamide, presence poly(vinylpyrrolidone). process allows fine control over thickness final wires, as well tunability number sharpness thorns. These new plasmonic nanostructures display extremely strong optical enhancing properties can be readily...
Abstract We introduce a new family of spiked particles resulting from the growth high aspect ratio gold nanorods. Upon spike growth, elongated beads are obtained with sizes above 300 nm. Interestingly, and in contrast to smooth same size, these spiked‐particles not only able sustain localized surface plasmon resonances consequently enhance Raman signals, but also big enough be recognized by standard confocal optical microscopy. These have been engineered into thin films test their...
