Journal ArticleDOI
Fabrication of poly(ethylene glycol) hydrogel microstructures using photolithography
Alexander Revzin,Ryan J. Russell,Vamsi K. Yadavalli,Won Gun Koh,Curt Deister,David D. Hile,Michael B. Mellott,Michael V. Pishko +7 more
TL;DR: Three-dimensional, cross-linked PEG hydrogel microstructures were immobilized on the surface and changes in fluorescence were also observed for immobilized fluorophore labeled acetylcholine esterase upon the addition of acetyl acholine.
Journal ArticleDOI
Metal enhanced fluorescence (MEF) for biosensors: General approaches and a review of recent developments
TL;DR: A general overview of metal-enhanced fluorescence biosensor systems from the basic mechanism to state-of-the-art biological applications and the pros and cons is provided.
Journal ArticleDOI
Poly(ethylene glycol) hydrogel microstructures encapsulating living cells.
TL;DR: Viability assays demonstrated that cells remained viable inside PEG-based hydrogel microstructures fabricated using photolithography after encapsulation for up to 7 days.
Journal ArticleDOI
Biomimetic strain hardening in interpenetrating polymer network hydrogels
David Myung,Won Gun Koh,J. Ko,Yin Hu,Michael R. Carrasco,Jaan Noolandi,Christopher N. Ta,Curtis W. Frank +7 more
TL;DR: In this paper, a mechanically enhanced interpenetrating polymer network (IPN) hydrogels with Young's moduli rivaling those of natural load-bearing tissues is presented.
Journal ArticleDOI
Molding of hydrogel microstructures to create multiphenotype cell microarrays.
TL;DR: Arrays of hydrogel microstructures encapsulating two or more phenotypes on a single substrate were successfully fabricated using multimicrofluidic channels, creating the potential for multiphenotype cell-based biosensors.
