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

04/21/23

•Quautium dots

•Carbon nanotubes

•Nanoparticles

Tracking and eliminating the tumor cells

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

500 x 500 micrometers

Transport of blood• liquid(blood viscosity and PH
