Tunable Photonic Multilayers From Stimulus-Responsive, Photo-Crosslinkable Polymers, Maria C. Chiappelli
Tunable Photonic Multilayers From Stimulus-Responsive, Photo-Crosslinkable Polymers, Maria C. Chiappelli
Doctoral Dissertations
This dissertation describes the synthesis of photo-crosslinkable copolymers and their utilization for the fabrication and testing of tunable and responsive one-dimensional (1D) photonic multilayers. Photonic multilayers exhibit structural color due to the interference of incident light at layer interfaces, providing a convenient route towards optically responsive materials that do not rely on potentially light- or oxygen-sensitive chromophore-containing pigments and dyes. A fabrication technique based on sequential spin-coating and crosslinking of photo-crosslinkable polymers is used to assemble tunable and responsive photonic multilayers. Chapter One introduces the fundamental underlying principles of 1D photonic structures and explores their importance in a variety of …

Stimuli-Responsive Supramolecular Assembly, Disassembly And Implications, Jing Guo
Doctoral Dissertations
Stimuli-responsive systems have attracted wide interest due to their applications in a variety of areas such as drug delivery and sensing. Stimuli-responsive systems that are triggered by secondary biological changes have been studied extensively. Primary biological changes, such as protein imbalances and enzymatic activity, are intrinsic to certain types of diseases, and thus have drawn increasing attention in triggering stimuli-responsive systems in areas such as drug delivery. This thesis first provides a concept of increasing stimuli-responsive selectivity by designing a system that only responds in the concurrent presence of two complementary primary biological stimuli, protein and enzyme. A dendritic assembly …
