Nanoliter analyte sensing on hybrid plasmonic-biosilica nanostructured materials

We developed a new strategy of optofluidic analysis from inkjet-printed droplets on photonic crystal biosilica-diatom at nanoliter scales. The hydrophilic diatom surface could concentrate target molecules in the liquid droplets as the solvent evaporates, which enables 2,4,6-trinitrotoluene (TNT) detection down to 2.7×10-15 grams by surface-enhanced Raman scattering (SERS). © 2016 The Authors.

Ultra-sensitive immunoassay biosensors using hybrid plasmonic-biosilica nanostructured materials.

We experimentally demonstrate an ultra-sensitive immunoassay biosensor using diatom biosilica with self-assembled plasmonic nanoparticles. As the nature-created photonic crystal structures, diatoms have been adopted to enhance surface plasmon resonances of metal nanoparticles on the surfaces of diatom frustules and to increase the sensitivity of surface-enhanced Raman scattering (SERS). In this...

Multifunctional Upconversion-Magnetic Hybrid Nanostructured Materials: Synthesis and Bioapplications

The combination of nanotechnology and biology has developed into an emerging research area: nano-biotechnology. Upconversion nanoparticles (UCNPs) have attracted a great deal of attention in bioapplications due to their high chemical stability, low toxicity, and high signal-to-noise ratio. Magnetic nanoparticles (MNPs) are also well-established nanomaterials that offer controlled size, ability ...

Redox Behavior of Nanostructured Molybdenum Oxide-Mesoporous Silica Hybrid Materials

Encapsulation of molybdenum oxide MoO3 into ordered mesoporous silica materials is demonstrated using different synthetic routes. Either supramolecular polyoxometalates of the “Müller type” or Na2MoO4 were used as precursors. Molybdenum oxide (MoO3)-silica hybrid materials were characterized using nitrogen-sorption experiments, transmission electron microscopy, small-angle X-ray scattering, and...
