D is false because by increasing the ionic concentration, the interaction becomes more complicated and determine how the physisorption is governed. E is true: that is where water molecules tends to interact one to the other, minimizing the exposition of hydrophobic regions B cannot C and D belongs to physisorption G is false: it is not really an alternative. SAM use chemisorption as one method…not an alternative. F no, there is at least one exception which is bovine serum protein, not containing RGD sequences and thus cells do not attach to them Micrometric roughness just accentuate the original effect, so the previous definition are the same, but you can get SUPER hydrophilic or SUPER hydrophobics surfaces 8. False because what you want is to have the highest affinity of the water-base protein solution with the final surface the stamp must be more hydrophobics than the final surface D false because capillarity can work reliably only in small channels The proteins attach to the region where the particles were, because you apply the solution before, preventing proteins to attach in the empty spaces
