Since the solvent evaporation of a droplet on a hydrophobically pretreated glass slide, femtomole amount of fluorescent materials is carried by the evaporation and results in outward capillary flow to the perimeter of the droplet spot where the solute deposits, and forms a fluorescent ring like deposit (RLD) with submicrometer-scale structures.
- Fluorescein,
- capillary flow effect,
- ring like deposit (RLD) technique,
- fluorescent microscopic analysis
