Micro-containers for collecting nanomaterials after medical treatment Speaker: Qian Xie Wenjing Xiao
why nanomaterials? • Normal drug delivery has disadvantage • reducing damage to normal cells • Other disease will come to body • Nanometerial aim at special cells
Type of nanomaterials • Quautium dots • Carbon nanotubes • Nanoparticles Tracking and eliminating the tumor cells 10/2/2014
ferromagnetic nanomaterial (FNMS) • Moving quick • Easy to control • Hyperthermia way (microwave)
Problem of remain material • Made by metal • Silver (toxic with diameter) Need to take them out --------------------Media(micro-contain)
How to conduct this experiment? The Size of Micro-Container: 200 ×200 ×200 cubic micrometers Gold-coated Nickel Frames Magnet "Blood Vessel"-Microfluidic Channels "Blood"-Viscous liquids Daniel S. Choi1, Jungrae Park2, Ke Xu1, Rose Kringel1, John J. Choi3, In Tak Jeon4, and Young Keun Kim4
500 x 500 micrometers Transport of blood • liquid(blood viscosity and PH
Magnet outside rotate Micro container rotate (efficient speed) 10/2/2014
ferromagnetic nanowire Micro-container Approximately 70% of Nanomaterials Can be Removed Nanowires microscope image Daniel S. Choi1, Jungrae Park2, Ke Xu1, Rose Kringel1, John J. Choi3, In Tak Jeon4, and Young Keun Kim4
