herbaceous plants are plants with very flexible stems. Their leaves and stems die down to soil level at the end of every growing season amd woody plants are plants with very strong and not easily bendable stems such as trees. Woody plants produce wood as a structural tissue

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
