Optimized allylamine deposition for improved pluripotential cell culture

Robust and Flexible Fabrication of Chemical Micropatterns for Tumor Spheroid Preparation

“…A simple and direct method to modify surfaces for biological applications is plasma micropatterning. , Plasma polymerization reliably produces thin conformal coatings with a broad range of chemistries relevant to the control of cellular adhesion. Of particular interest are amine-rich plasma-polymerized coatings that significantly enhance cell adhesion. ,− The thickness of plasma polymer layers can be easily controlled, and uniform layers can be prepared over large surface areas. Plasma-based surface methods for cell patterning can be divided into plasma etching, plasma wetting-controlled deposition patterning, and grafting of nonfouling polymer films and/or fouling polymeric films. − These methods rely on the use of multiple plasma processes to prepare cell-adhesive and nonadhesive areas on the substrate or upon removal of photolithographic patterned regions to create cell-binding patterns.…”

Electrochemical Polymerization of Allylamine Copolymers

“…The peak at 285 eV relates to aliphatic carbon (C–C), while the signal at 286.6 eV corresponds to carbon atoms bound to an amine, imine, or oxide/hydroxy groups (C–N, C=N, and C–O). A fourth component at 288.0 eV is assigned to carbonyl groups (C=O) and amide bonds (N–C=O) . Finally, the peak at 289.2 eV is attributed to the presence of carboxylic species (O–C=O).…”

“…The C 1s core-level spectrum (Figure 5) recorded at 90°takeoff angle has been fitted with five components: a first peak at 284.4 eV (C=C) is assigned to sp 2 -hybridized carbon mainly originating from the GC substrate. The peak at 285 eV relates to aliphatic carbon (C− 17 Finally, the peak at 289.2 eV is attributed to the presence of carboxylic species (O−C=O). Any attempt to fit the C 1s spectra with more than five components has resulted in significant uncertainty (see Table S2 in Supporting Information for the distribution of the deconvolution).…”

Biofunctional porous silicon micropatterns engineered through visible light activated epoxy capping and selective plasma etching

“…Plasma processes have been extensively used for biofunctionalization purposes in a diversity of configurations. The most extended mode, plasma polymerization (an alternative name for plasma enhanced chemical deposition of strictly organic monomers) has been used for deposition of amines [15,16], carboxylic acid [17,18] and other chemical functionalities.…”
