The direct application of this work is the restraint of laboratory mice for biological imaging of micron- and submicron-scale biological structures. No existing research has measured the shear stiffness of mouse facial tissue or modeled the effect of quasi-conformal contact constraints on nonlinear materials. The constraint devices and techniques currently available for mice have limitations that have prevented further exploration of their biological structures. The theoretical model, design rationale, and testing results of a prototype device utilizing quasi-conformal constraints are presented in this thesis. This device is capable of restraining anesthetized mice to sub-micron movement in all axes of translation, without additional surgery or discomfort to the mouse. With the findings presented in this thesis, the design of further optimized devices can be made-both for anesthetized and awake mice-enabling further studies in bone marrow and neural activity that are currently impossible. This could ultimately lead to breakthroughs in stem cell and neurobiological research.","abstract_html":"The purpose of this work is the modeling and prototyping of quasi-conformal constraint contacts and the investigation of their positioning ability for compliant bodies, specifically for the holding of mice in optical imaging setups.
