The specific objectives of this investigation were to 1) develop a microfluidic-based in vitro 3D breast cancer tissue model that can mimic the heterogeneous cancer microenvironment and emulate physiologic conditions, 2) evaluate breast cancer tissues for PDT efficacy by dynamically injecting therapeutic agents (i.e. PS and Au NPs) and studying their distribution profiles, and 3) investigate the effects of light penetration on PDT by providing a suitable depth of cancer tissue
