Graphical Abstract
  • ; essentially, the well-known dimensions of n-alkanethiol monolayers furnish an in situ ruler for local measurements of the thickness of molecular films [7][34][35][36]. Our protocols for nanografting used either dodecanethiol or TMMH as matrix SAMs that were prepared by immersion in ethanolic solutions. Areas
  • the TMMH matrix. Since a double layer of MUA would be 3.0 nm thick, this analysis likewise indicates a height of ~1 nm for the SAM derived from TMMH. Further experiments were conducted with nanografting of TMMH nanopatterns within a methyl-terminated dodecanethiol SAM (Figure 7). The dodecanethiol SAM
  • was prepared from 1 mM ethanolic solution, and the TMMH nanografted patterns were prepared with 0.01 mM solution. The expected thickness of a dodecanethiol SAM is 1.5 nm, as a reference for evaluating the thickness of TMMH nanostructures. Four nanopatterns were written within the methyl-terminated SAM

Graphical Abstract
  • (THMA) and dodecanethiol (DT), was studied. The response towards ammonia, nitrous oxide and nitrogen dioxide was investigated for three sensor configurations, namely pure ZnO nanowires, organic-coated ZnO nanowires and ZnO nanowires covered with a sparse layer of organic-coated ZnO nanoparticles
  • in response caused by sensor batch variations being misconstrued as a result of the functionalisation process. The first ligand studied was dodecanethiol (DT), which can readily form a self-assembled monolayer at the ZnO surface simply by exposure of the nanowires to an ethanolic solution containing
  • several plates or wires. Ex situ functionalisation of NP- and NW-powder ZnO samples by either DT or THMA was confirmed by FTIR measurements. The FTIR spectra given in Figure 3 are of a ZnO nanowire sensor sample and samples that had been exposed to either 10 mM dodecanethiol or THMA solution for 24 h

Graphical Abstract
  • qualitative analysis of the HRXPS spectra, we estimated the packing density and effective thickness of the target films on the basis of the HRXPS data. The packing density was estimated by a comparison of the S2pthiolate/Au4f intensity ratios of the target films with those for the reference dodecanethiol (DDT
