Abstract: Successive layer properties and peptide insertion in an assembly of supported mobile phospholipid bilayers on polyion/alkylthiol layer pairs were investigated in a combined optical, electrochemical, and surface topography study using surface plasmon resonance (SPR), cyclic voltammetry (CV), and atomic force microscopy (AFM). The use of a long-chain alkylthiol in this assembly was too insulating, and thus, a short-chain alkylthiol was used to probe membrane electrochemical properties. Using AFM, we found that t… Show more

“…The power spectral density (PSD) describes the contributions of different spatial frequencies to the RMS roughness. [16,20,29] PSD distributions of the OTS passivated, roughened oxides are shown in Figure 3. The overall power spectral density (PSD) increases with RMS roughness over the entire wavelength range from (15 to 1000) nm, indicating increasing fractal roughness.…”

“…Such cushions have consisted of hydrogels, polymeric tethers, polymer films and polyelectrolyte multilayers (PEMs) [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. PEMs offer the following advantages [29][30][31][32][33][34]36]: (1) they are robust and easy to fabricate, (2) they can be deposited on virtually any surface, (3) they can provide a reservoir for electron transfer mediators and cofactors for sensor applications, and (4) their porosity and flexibility may allow the protein to exist in its natural conformation while bound to the BLM.…”

“…The design, characterization and synthesis of new materials with functional organization at nanoscale enable us to engineer and control functional bio-integrated systems. In addition, AFM offers the possibility of in situ imaging of growing surfaces under potential control (Ikemiya et al 1996;Vidu and Hara 1999a, b;Vidu et al 2001Vidu et al , 2006Vidu et al , 2007Vidu et al , 2012; Ku et al 2004) or interacting soft surfaces such as lipids with proteins Zhang et al 2002;Carmichael et al 2004).…”
