Journal ArticleDOI
Photonic wire biosensor microarray chip and instrumentation with application to serotyping of Escherichia coli isolates
Siegfried Janz,D.-X. Xu,Martin Vachon,N. Sabourin,Pavel Cheben,H. McIntosh,Heping Ding,Shurui Wang,Jens H. Schmid,André Delâge,Jean Lapointe,Adam Densmore,Rubin Ma,W. Sinclair,S.M. Logan,R. MacKenzie,Q. Y. Liu,D. Zhang,G. Lopinski,O. Mozenson,M. Gilmour,H. Tabor +21 more
TL;DR: A complete photonic wire molecular biosensor microarray chip architecture and supporting instrumentation is described, used to demonstrate a multiplexed assay for serotyping E. coli bacteria using serospecific polyclonal antibody probe molecules.
Journal ArticleDOI
Sensitive Label-Free Biomolecular Detection Using Thin Silicon Waveguides
Adam Densmore,Dan-Xia Xu,Siegfried Janz,Philip Waldron,Jean Lapointe,T. Mischki,G. Lopinski,André Delâge,Jens H. Schmid,Pavel Cheben +9 more
TL;DR: In this paper, high-index-contrast silicon photonic wire waveguides of submicrometer dimension are used for the detection of biological molecules, which are compatible with commercial spotting apparatus and microfluidic-based analyte delivery systems.
Journal ArticleDOI
Functionalization of Si(111) surfaces with alkyl chains terminated by electrochemically polymerizable thienyl units
TL;DR: A Si(111) surface has been derivatized with a thiophene-terminated alkyl monolayer which was subsequently photoanodically oxidized in the presence ofThiophene to yield a strongly adherent and smooth conducting film.
Patent
Grating-based evanescent field molecular sensor using a thin silicon waveguide layer
Bill Sinclair,Jens H. Schmid,Siegfried Janz,Philip Waldron,Dan-Xia Xu,Adam Densmore,T. Mischki,Jean Lapointe,Daniel Poitras,G. Lopinski +9 more
TL;DR: In this article, a detection scheme that simultaneously couples a polarized beam to a single mode of a waveguide, and couples the polarized beam out of the waveguide to specularly reflect the beam by the same grating is presented.
Proceedings ArticleDOI
A fully integrated silicon photonic wire sensor array chip and reader instrument
Adam Densmore,Dan-Xia Xu,N. Sabourin,H. McIntosh,Pavel Cheben,Jens H. Schmid,Rubin Ma,Martin Vachon,Andre Delage,W. Sinclair,Jean Lapointe,Y. Li,G. Lopinski,Boris Lamontagne,Siegfried Janz +14 more
TL;DR: In this paper, a complete instrumentation system for interrogating silicon photonic wire waveguide sensor array chips has been built and demonstrated, which is designed to read 16 or more sensors on a single silicon chip simultaneously and in real time, while delivering sample fluid to the sensors through microfluidic channels fabricated monolithically on the chip.
