WebApr 11, 2024 · The protein density within the field width is 20 mg mL −1 which can be directly linked to refractive index change via the mean protein refractive index increment of 0.190 mL g −1. From this calculation, we estimate Δ n ≈ 4 × 10 −3 RIU, which agrees with the experimental values obtained for the binding of α -IgG and α -CRP. WebNov 13, 2024 · In addition to increasing the density of the SWCNT network, ... Only an APTES monolayer (~0.7 nm thick) must be created prior to SWCNT deposition, as additional APTES beyond such a monolayer results in less uniform SWCNT layers. In order to remove excess APTES, 99.9% IPA was squirted across each sample in three cycles of 2 min of …

WebMay 7, 2024 · It is worth noting that the specific area provided by the manufacturer corresponds exactly to the one calculated from the diameter of the hard sphere nanoparticles obtained by SAXS (27.6 nm), assuming a silica density of 2.1. There are thus no internal porosities within the nanoparticles, nor agglomeration between nanoparticles. WebFirst, a calibration curve was prepared by reacting 1 mL of each ethanolic APTES solution (concentrations varying from 1x10 −2 to 5x10 −4 M) with 1 mL of 5% (w/v) ninhydrin. The NH 2 group concentration for each sample was carried out by suspending 5 mg of it in 1 mL of ethanol plus 1 mL of ninhydrin 5% (m/v) solution.
