View from above of fused silica chip.
In the image is fused silica and the black line is burned fused silica caused by laser, when I cast droplet that contains molecules, never mind which kind of aggregation I tried different kinds of molecules, the aggregation is more preferably on the burned fused silica rather than unburned fused silica, the burning it seems that it caused to a groove in the sample.. so I have two questions:
1- Why the molecules prefer to aggregate more on the burned region, what is the physics behind that??
2- Could the result be changed if the burned region is like a bump and not a groove?
Thank you,
