There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Micro-scale Characterization of Breast Cancer Using MEMS and Robotics
Abstract:
According to the cancer statistics from the American Cancer Society, breast cancer is the most common type of cancer in females and continues to be the second leading cause of cancer-related female deaths in the US. As breast cancer progresses, the microenvironment around cancerous breast tissues undergoes a physical reconfiguration to be tumor-permissive. The capability to monitor the signatures of cancer progression in breast tissue is important for improving the accuracy of diagnosis and early detection, which is critical factors for successful treatment and recovery of the patient. The goal of this project is to develop experimental and computational tools to characterize the onset and progression of cancer in human breast tissue at the micro-scale as additional diagnostic methods. More specifically, the dissertation consists of the following three research areas:
1) design, development, and control of micro-manipulators capable of ex vivo tissue indentation, 2) design and fabrication of micro-electromechanical system (MEMS) based sensors, which are a subsystem of the indentation system, for measuring various physical properties of human breast tissues, and 3) analysis and validation of the properties as biomarkers for breast cancer. The ex vivo experimental results show that the proposed system can capture various physical properties of human breast tissues reliably and distinguish cancerous tissues from normal breast tissues. Development of a system for in situ breast tissue characterization as a proof-of-concept is also included to provide a more practical way of breast cancer diagnosis.
