A few of the Ti films with typical surface stoichiometries of combinations of oxygen and nitrogen exhibited minimum bacterial attachment, and on the modified HA films relatively less attached bacteria were recorded.
FACS analyses also showed the expression of typical surface markers of both DCs (CD40, CD80, CD86, MHC class II, and CCR7), although the expression level of each antigen varied between conventional DCs and expanded DCs (conventional DCs > expanded DCs: CD40, conventional DCs = expanded DCs: CCR7, and conventional DCs < expanded DCs: CD80, CD86 and MHC class II) (Fig. 2b).
While the team say it is not clear whether the bacteria found are part of the typical surface flora of the fish species, they are now working to unpick which particular substances within the chemical mixtures are behind the antimicrobial effects.
In most of these applications, the typical surface sensitivity of the nanowire structure is often a disadvantage.
Two types of cells had similar morphologies and typical surface markers of MSCs, such as positive expression for CD13, CD44, CD90, and CD105 and negative expression for hematopoietic stem cells marker phenotypes of CD14, CD34, and there was no significant statistical difference in expression levels.
Thin films produced by sol gel approach display excellent uniformity with typical surface roughness of ≈10 30 nm and a mean grain size of ≈100 nm, as determined by AFM surface topography.
A typical surface structure of TiO2 nanotubular layer, well aligned nanotubes with inner diameter of 70 100 nm and wall thickness of about 10 15 nm was obtained.
Electrochemical etching of Si wafers produced uniformly distributed pores of size ~1 μm. Figure 1c, d shows typical surface morphology of as-deposited and patterned Fe films, respectively, on mirror-polished Si wafers.
This is schematically shown in Fig. 3, where the typical surface topography of the surface (a) is represented together with a suggested representation of the surface potential (b).
This limit is about 10 ions per cm for inorganic materials [3,27] and ∼10 cm−2 for organic materials [4,27] and depends on the sputter yield of the primary ion, ion energy, target surface, etc. (a typical surface consists of ∼10 atoms cm−2).
