Monolithically integrated dye-doped PDMS long-pass filters for disposable on-chip fluorescence detection
Oliver Hofmann,Xuhua Wang,Alastair Cornwell,Stephen J. Beecher,Amal Raja,Donal D. C. Bradley,Andrew J. deMello,John C. deMello +7 more
TL;DR: The fabrication of high quality monolithically integrated optical long-pass filters, prepared by incorporating dye molecules directly into the microfluidic chip substrate, thereby providing a fully integrated solution that removes the usual need for discrete optical filters.
Three-Dimensional Microfluidic Confinement for Efficient Sample Delivery to Biosensor Surfaces. Application to Immunoassays on Planar Optical Waveguides
TL;DR: A microchip-based flow confinement method for rapid delivery of small sample volumes to sensor surfaces is described, and with the faster binding, sample consumption was reduced by 96% compared to conventional whole-channel sample delivery.

Thin-film organic photodiodes as integrated detectors for microscale chemiluminescence assays
Oliver Hofmann,P. F. Miller,Paul Sullivan,Tim Jones,John C. deMello,Donal D. C. Bradley,Andrew J. deMello +6 more
TL;DR: In this paper, the use of thin-film organic photodiodes as integrated optical detectors for microscale chemiluminescence was reported, with a detection limit of ∼1mM and linearity over at least three decades.

Integrated thin-film polymer/fullerene photodetectors for on-chip microfluidic chemiluminescence detection
Xuhua Wang,Oliver Hofmann,Rupa Das,Edward M. Barrett,Andrew J. deMello,John C. deMello,Donal D. C. Bradley +6 more
TL;DR: The combination of organic photodiodes with PDMS microfluidic chips offers a means of creating compact, sensitive and potentially low-cost microscale CL devices with wide-ranging applications in chemical and biological analysis and clinical diagnostics.
Modular approach to fabrication of three-dimensional microchannel systems in PDMS-application to sheath flow microchips.
TL;DR: A modular approach to fabrication of three-dimensional microchannel systems in polydimethylsiloxane (PDMS) is presented, based on building blocks with microstructuring on up to three faces, which was applied to the fabrication of a 3D-sheath flow microchip.
