Clinical Trial (임상시험)
New drug development
In pre-clinical research, we should test
✓ Toxicity and Efficacy✓ Test first on animal models✓ Whether it is safe to test on human

The history of Organ-on-a-chip
Neutrophil Chemotaxis
“Old” Tools Still Used in Biology
No Control Over Individual Cells, Cell-ECM and Cell-Cell Interactions
Custom “Apartments for Cells”and “Communities of Cells”
• Micrototal Analysis System (μTAS) • Genomic analysis• Protein analysis• High throughput screening• Cell Biology and Neuroscience
microfluidic gene sequencing LabChip µTAS (Caliper)
manipulation of fluids in small channels
Cell Sorter (Fluidigm)
Microfluidics
Multiscale Control of Cellular Microenvironments
2D Culture
Petri-dish culture
Life is in 3D
✓ Soluble gradients absent
✓ Forced apical-basal polarity
✓ Continuous layer of matrix
✓ Unconstrained spreading in x-y plane
✓ Adhesions restricted to x-y plane
✓ High stiffness
