Nanoliter analyte sensing on hybrid plasmonic-biosilica nanostructured materials

چکیده
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.

Detecting explosive molecules from nanoliter solution: A new paradigm of SERS sensing on hydrophilic photonic crystal biosilica.
We demonstrate a photonic crystal biosilica surface-enhanced Raman scattering (SERS) substrate based on a diatom frustule with in-situ synthesized silver nanoparticles (Ag NPs) to detect explosive molecules from nanoliter (nL) solution. By integrating high density Ag NPs inside the nanopores of diatom biosilica, which is not achievable by traditional self-assembly techniques, we obtained ultra-...

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...

متن کاملOptofluidic concentration: plasmonic nanostructure as concentrator and sensor.
The integration of fluidics and optics, as in flow-through nanohole arrays, has enabled increased transport of analytes to sensing surfaces. Limits of detection, however, are fundamentally limited by local analyte concentration. We employ the nanohole array geometry and the conducting nature of the film to actively concentrate analyte within the sensor. We achieve 180-fold enrichment of a dye, ...

Diatoms are single-celled algaes that make photonic-crystal-like silica shells or frustules with hierarchical micro& nano-scale features consisting of two-dimensional periodic pores. In this paper, we present an innovative label-free optical sensor based on a biological-plasmonic hybrid nanostructure by self-assembling silver (Ag) nanoparticles into diatom frustules. The photonic-crystal-like d...
