During the game of " Tetris ", blocks appear to adsorb onto the lower surface of the window. 43. Gold also does not form oxides; it adsorbs organic contaminants from the air, but these are easy to remove. 44. The non-polarity of PDMS allows for biomolecules to readily adsorb to its surface in order to lower interfacial energy. 45.
