Is worth noting that the adsorbed molecules on the Cy5-DBCO site surface mostly consist of water molecules and not volatile organic compounds (VOCs). In our prior work [15], we showed that the rate of adsorption of VOCs around the gold surface is a lot slower than the price of adsorption of the molecularly adsorbed water layer around the surface.- confidential -Appl.

WeWe break down the USDC into 3 stages:(i) onset of condensation, (ii) growth of multilayer film up to 8 8 nm, and (iii) thin-film development much more than 8 nm. (ii) development in the the multilayer film as much as nm, and (iii) thin-film development far more than eight nm. These stages separated by the presence and/or size from the thin film in between droplets. These stages are are separated by the presence and/or size ofthe thin film amongst droplets.
