Physicochemical characterization of covalently bonded alkyl monolayers on silica surfaces

Universal Gradient Substrates for “Click” Biofunctionalization

“…For a given position, the fraction of total alkylsilane sites at which the functionalization and RGD linking conversion occurred within the XPS scan area was calculated by determining the local ratio of nitrogen to carbon. Finally, the extent of RGD linkage to the surface was converted to density based on the peptide molecular weight and the original alkylsilyl brush density [37].…”

“…The nitrogen-to-carbon ratios were used to extract the fraction of alkylsilane-RGD linkages per area on the surface. Finally, from the SAM density [37] and peptide molecular mass we were able to calculate the actual immobilized peptide concentration (Fig. 2B).…”

Determination of the Main Forces Driving DNA Oligonucleotide Adsorption onto Aminated Silica Wafers

“…Modificaretain the ability to hybridize with their complementary tion of the silicon oxide surface by covalent binding of sistrands. Adsorption process of DNA or RNA onto solid sur-lanes with surface silanol groups has been studied by several faces such as mica (6), glass particles (7), sand (8), or silica groups (24)(25)(26)(27). Layer formation and its nature were shown wafers (9) is well documented.…”

On the charge storage and decay mechanism in silicon dioxide electrets

“…This grafting process and the subsequent chromatographic measurement to determine the density of the grafted chains have been carried out by Martelet and coworkers [20], The details of the preparation of octadecyl dimethyl (dimethylamino) silane, the grafting process and the density measurements are reported in one of their papers [20].…”
