The microchannel for integrated sensing system using porous nano-fiber membrane |
| 초록 |
Effective treatment of disease requires a sensitive, accurate, and rapid diagnostic platform. Before diagnosing current clinical trials, the process of separating red blood cells and white blood cells from blood is performed. This process not only increases the concentration of the biomaker from the blood, but also enables efficient biomarker detection. To perform the separation, a nanofiber made by electrospinning is formed on a poly-dimethysiloxane (PDMS) microfluidic chip to form a blood separation chip. Nanofibers are hydrophilic polymers that allow blood to pass through the pores and are used to filter red blood cells (about 6 μm) and leukocytes (12 μm ↑) with a 3D nanostructure with nano size pores. Nano fiber is made using polyvinylpyrrolidone / polyethersulfone (PVP / PES), which has gradient porosity from 30 μm to 5 μm, enabling efficient blood filtration. |
