An investigation of cell adhesion and growth on micro/nano-scale structured surface-Self-assembled micro particles as a scaffold

- Most cells are selectively adhered on micro-structured silica particles, while a flat surface has low affinity for the cells.
- Angular silica micro/nano-structure that has a height of 1 μm is suited for cell selective adhesion.
- Fine gaps among assembled particles have some effects on cell adhesiveness and growth.
