Electrodeposition of alginate/chitosan layer-by-layer composite coatings on titanium substrates

Relevant insight of surface characterization techniques to study covalent grafting of a biopolymer to titanium implant and its acidic resistance

“…For example, it can be found in exoskeletons of crustaceans and insects as well as in some fungi and microorganisms [18]. Various strategies such as electrodeposition of alginate/chitosan layer-by-layer on substrates [19], the use of catechol groups [20] and dopamine-glutaraldehyde system [21] have been already reported to bond chitosan to titanium. Another widespread approach consists in using organosilane as coupling agent such as triethoxysilylbutyraldehyde (TESBA) [22,23], triethoxysilylpropylsuccinic anhydride (TESPSA) [24] or 3-aminopropyltriethoxysilane (APTES) associated with glutaraldehyde [25][26][27].…”

Layer-by-layer immobilization of quaternized carboxymethyl chitosan/organic rectorite and alginate onto nanofibrous mats and their antibacterial application

“…ALG is a biodegradable linear polysaccharide made of (1 → 4) linked ␤-d-ManA and ␣-l-GulA units in varying proportions (Wang et al, 2014). ALG possesses properties of non-toxicity, low cost and hydrophilicity, and it is negatively charged from the carboxylate groups (Shalumon et al, 2011).…”

Electrophoretic Deposition and Characterisation of Chitosan Coatings on Near-Β Titanium Alloy

“…Keywords: chitosan, Ti-13Nb-13zr alloy, electrophoretic deposition, coating under an electric field [25,26]. The uniformity of the coating is very important for the development of high-quality implants.…”
