Effect of Multilayer Termination on Nonspecific Protein Adsorption and Antifouling Activity of Alginate-Based Layer-by-Layer Coatings

Abstract: Layer-by-layer (LbL) assembly is a versatile platform for applying coatings and studying the properties of promising compounds for antifouling applications. Here, alginate-based LbL coatings were fabricated by alternating the deposition of alginic acid and chitosan or polyethylenimine to form multilayer coatings. Films were prepared with either odd or even bilayer numbers to investigate if the termination of the LbL coatings affects the physicochemical properties, resistance against the nonspecific adsorption … Show more

“…Ellipsometry is a powerful optical technique for thin film characterization, based on measuring the change in light polarization upon oblique reflection. Its non-destructive nature, high accuracy, simplicity and availability make ellipsometry an essential tool in various fields of industry and research, such as semiconductors [1][2][3], photovoltaics [4,5], materials characterization [6,7], optical coatings [8,9], two-dimensional materials [10,11], flat panel displays [12][13][14], organic films and surfaces [15,16], antifouling coatings [17,18], biological materials [19,20] and many more.…”

“…Various strategies, including self-assembly, physical or chemical cross-linking, and phase separation by heat treatment, have been well developed for producing protein coatings . Compared to cross-linking and thermal treatment, layer-by-layer (LbL) assembly has attracted intensive attention due to its mild fabrication conditions to store the bioactivity of the deposited protein, easy operation, good control of the thickness of the coating on the nanoscale, independence of the shape of substrates, etc. However, as a bottom-up strategy, LbL normally exhibits linear growth and is time-consuming since alternative deposition must be repeated many times until reaching the desired thickness . An LbL coating with fast growth (exponential growth mode) is always popular due to few required repeats, which was realized by tuning the conformation of the polyelectrolyte chain in coatings assembled from classic pairs of polyelectrolytes .…”

“…The 3D structure of the rLbL may potentially be a scaffold for multilayer enzyme immobilization on electrodes useful for cascade reactions. 28 On the other hand, amino-terminated surfaces show good results in cell adhesion, 35 protein adsorption, 36 DNA immobilization, 37 and enzyme loading capability as a biointerface. 34 The rLbL nanogel is considerably homogeneous as generated on the gold surface and allows electron transfer.…”
