Journal ArticleDOI
Spatially controlled synthesis of silver nanoparticles and nanowires by photosensitized reduction
Safi Jradi,Lavinia Balan,Xinhua Zeng,Jérôme Plain,Daniel-Joseph Lougnot,Pascal Royer,Renaud Bachelot,Suzanna Akil,Olivier Soppera,Loïc Vidal +9 more
TL;DR: The present paper reports on the spatially controlled synthesis of silver nanoparticles (NPs) and silver nanowires by photosensitized reduction by direct photogeneration and a photochemically assisted procedure allowing silver to be deposited at the surface of a polymer microtip.
Journal ArticleDOI
Rapid fabrication of micro-nanometric tapered fiber lens and characterization by a novel scanning optical microscope with submicron resolution.
Shouguo Zheng,Xinhua Zeng,Wei Luo,Safi Jradi,Jérôme Plain,Miao Li,Philippe Renaud-Goud,Régis Déturche,Zengfu Wang,Jieting Kou,Renaud Bachelot,Pascal Royer +11 more
TL;DR: The ability to manufacture a reference tapered fiber lens with high symmetry at sub-wavelength scale with a wide range of geometry control is demonstrated, either for the length from several hundred nanometers to several hundred microns, or for the curvature radius on the endface of a single mode fiber.
Journal ArticleDOI
Direct functionalization of an optical fiber by a plasmonic nanosensor
Xinhua Zeng,Safi Jradi,Julien Proust,Renaud Bachelot,Zhenquan Zhang,Pascal Royer,Jérôme Plain +6 more
TL;DR: A rapid route for fabricating silver nanoparticles at the end of an optical fiber using a fiber integrated plasmon-based sensor and the effect of the refractive index of different solvents on the extinction spectra is explored.
Journal ArticleDOI
Fast and accurate determination of organophosphate pesticides using surface-enhanced Raman scattering and chemometrics
Shizhuang Weng,Shizhuang Weng,Miao Li,Chen Cheng,Chen Cheng,Gao Xiang,Gao Xiang,Shouguo Zheng,Xinhua Zeng +8 more
TL;DR: In this paper, the authors developed an approach for the fast and accurate determination of organophosphate pesticides by combining surface-enhanced Raman scattering (SERS) technology with chemometric methods.
Journal ArticleDOI
Integration of polymer microlens array at fiber bundle extremity by photopolymerization.
Xinhua Zeng,Jérôme Plain,Safi Jradi,Claire Darraud,Frédéric Louradour,Renaud Bachelot,Pascale Royer +6 more
TL;DR: A novel route to directly integrate an array of microlenses at the extremity of an optical fiber bundle based on photopolymerization at the end of the fiber is presented.
