Scheme of the two copolymers adsorbed on Nb2O5 surfaces: a PLL-PMOXA with n number of 2-methyl-2-oxazoline (MOXA) repeating units, grafting density α = x/(x + y) and b PLL-PEG with m number of ethylene glycol (EG) repeating units, grafting density α = j/(j + k). The number following the polymer abbreviation (PMOXA, PEG) indicates the molecular weight in kDa
