Hydrogels with A Camphorquinone-Triethanolamine Photoinitiator By Wenlu Wang A thesis submitted to Johns Hopkins University in conformity with the requirements for the degree of Master of Science in Engineering Baltimore, Maryland WebDec 10, 2010 · Abstract. We describe the fabrication of photopatterned actuators, composed of stimuli-responsive hydrogel bilayers made from N-isopropyl-acrylamide (NIPAm), acrylic acid (AAc), and poly-ethylene oxide diacrylate (PEODA). The hydrogels were deposited by spin coating and casting and were patterned by non-contact photolithography.

WebFurthermore, by using the photolithographic technique, gel-sol photopatterning was successfully conducted to produce sol spots within the gel matrix. The fabricated gel-sol pattern not only allowed regulation of bacterial motility in a limited area, but also off/on switching of F1-ATPase rotary motion at the single-molecule level. WebChemically, this highly accessible photolithographic gel shaping approach has been achieved through either: (1) phototriggered photopolymerization/covalent crosslinking (which typically formed covalently crosslinked gels);41,44-46 or (2) photoactivated changes in the ionic crosslinking and/or ionization (which occurred through either a ...
