Pattern formation of antifreeze glycoproteins via solvent evaporation.
Surface patterning of antifreeze glycoprotein fraction 8 (AFGP 8) via a solvent evaporation method is reported here. In this process, lines of AFGP 8 particles and gridlike patterns were formed as as result of the receding of the droplet contact line and the accumulation of the solute during evaporation. The solution concentration strongly affects the protein line spacing. The average height of the protein was measured to be 8.1 +/- 2.5 A, which may be attributed to the height of a single molecule.
