Journal ArticleDOI
An efficient two-photon-generated photoacid applied to positive-tone 3D microfabrication
Wenhui Zhou,Stephen M. Kuebler,Kevin L. Braun,Tianyue Yu,J. Kevin Cammack,Christopher K. Ober,Joseph W. Perry,Seth R. Marder +7 more
TL;DR: A two-photon-activatable photoacid generator, based on a bis[(diarylamino) styryl]benzene core with covalently attached sulfonium moieties, has been synthesized and was used in conjunction with a positive-tone chemically amplified resist for the fabrication of a three-dimensional (3D) microchannel structure.
Journal ArticleDOI
Photoresponsive Hydrogel Microstructure Fabricated by Two‐Photon Initiated Polymerization
Toshiyuki Watanabe,M. Akiyama,Kenro Totani,Stephen M. Kuebler,Francesco Stellacci,Wim Wenseleers,Kevin L. Braun,Seth R. Marder,Joseph W. Perry +8 more
TL;DR: In this paper, a photoresponsive polymeric hydrogel cantilever that deflects under illumination was fabricated by using two-photon three-dimensional lithography.
Journal ArticleDOI
Design and application of high-sensitivity two-photon initiators for three-dimensional microfabrication
Stephen M. Kuebler,Kevin L. Braun,Wenhui Zhou,J. Kevin Cammack,Tianyue Yu,Christopher K. Ober,Seth R. Marder,Joseph W. Perry +7 more
TL;DR: In this article, a photoacid generator (PAG) is described that can be efficiently activated by two-photon excitation (TPE) and can be used for high-sensitivity three-dimensional micro-patterning of acid-sensitive media.
Journal ArticleDOI

TL;DR: In this paper, photo-crosslinkable resins were formulated with these initiators and were used to fabricate a variety of complex three-dimensional structures by two-photon induced polymerization (TPIP).
Journal ArticleDOI
Fast Hadamard transform capillary electrophoresis for on-line, time-resolved chemical monitoring.
TL;DR: The capability of fHTCE to perform time-resolved monitoring of changes in the concentration of model neurochemical compounds and improved signal-to-noise ratios with a total analysis time under 10 s is demonstrated.
