“…The great interest in this kind of materials is raised from the fact that the building blocks of di- or tri-copolymers are usually immiscible functional groups, which as a consequence allows them to self-assemble in well organized nanoscale periodic structures. Typically these are spherical, cylindrical or lamellar forms, depending on the composition of the copolymers [ 71 , 72 ].…”

This review describes different strategies of surface elaboration for a better control of biomolecule adsorption. After a brief description of the fundamental interactions between surfaces and biomolecules, various routes of surface elaboration are presented dealing with the attachment of functional groups mostly thanks to plasma techniques, with the grafting to and from methods, and with the adsorption of surfactants. The grafting of stimuli-responsive polymers is also pointed out. Then, the discussion is focused on the protein adsorption phenomena showing how their interactions with solid surfaces are complex. The adsorption mechanism is proved to be dependent on the solid surface physicochemical properties as well as on the surface and conformation properties of the proteins. Different behaviors are also reported for complex multiple protein solutions.

“…The surface‐energy components and basic character were determined by contact‐angle measurements (Fowkes and Owens–Wendt method), the surface charge by streaming‐potential monitoring, the O/C (N/C) ratio by XPS analysis, and the surface roughness by atomic force microscopy (AFM) imaging. The surface characteristics, as a function of the plasma conditions and the polymer‐to‐surfactant ratio, have been reported in detail previously 30, 31…”

“…The detailed experimental setup and the protocols for the surface modification of the poly(propylene) (PP) substrates and Eppendorf tubes have been reported in our recent publication 30. Briefly, the cleaned and dried supports were exposed to capacitatively coupled radio‐frequency helium plasma and, afterwards, immersed into two different polymer solutions: MIX I (PNIPAM, 0.5 g L −1 + CTAB, 10 −3 M ) and MIX II (PNIPAM + Tween 20, W T = 0.05%) at a 1:1 volume ratio.…”

New nonfouling tubes are developed and their influence on the adhesion of neuroproteins is studied. The biomarkers are considered as single components (recombinant prion and Tau proteins) or in a solution of native and pathological forms. The samples are stored for 24 h at 4 °C in virgin and treated tubes layered with two different nanostructured coatings based on poly(N-isopropylacrylamide) with either a positive or a neutral charge, and the protein adhesion is monitored. The recombinant protein with a high pI is repelled from the nanostructured surface that has a negative ζ potential, whereas the recombinant protein with the lower pI is attracted. Furthermore, in the case of complex solutions, neutral nanostructured surfaces are able to retain all amyloid biomarkers.

“…The literature reports on almost all types of polymers (PC, PMMA, PET, PEEK, PS, silicone, elastomers …) which have been plasma-modified to present textured surface when subjected to different plasma phases (mainly O2, CF4, Ar and their mixtures….) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The subsequent pattern is depending on plasma parameters.…”
