Biomimetic strategies in colloidal-electrochemical deposition of functional materials and composites using chenodeoxycholic acid

Multifunctional Properties of Commercial Bile Salts for Advanced Materials Engineering

“…BSs were used for the dispersion of carbon nanoclusters, [ 93 ] graphite, [ 94 ] carbon dots, [ 95 ] and diamonds. [ 95,96 ] The adsorption of BSs on diamond, nanodiamond, and carbon dots allowed for the formation of electrostatically stabilized suspensions, which facilitated the fabrication of composites by colloidal methods. [ 95,96 ] The nanodiamond–sodium cholate complex [ 97 ] was used for the fabrication of an advanced fluorescent material for applications in displays.…”

“…The deposition mechanism of BAs is based on their pH‐dependent charge and solubility, gel‐forming, and film‐forming properties. The EPD of cholic acid, [ 98 ] deoxycholic acid, [ 99 ] and chenodeoxycholic acid [96a] was conducted from solutions of their corresponding salts. The deposition mechanism involved BSs dissociation, electrophoretic transport of the anionic species to the anode surface, where local pH decrease resulted in their protonation, charge neutralization, and formation of BA films.…”

“…BSs were used as charging, dispersing, and film‐forming agents for the deposition of micrometer‐size diamond ( Figure ) and nanodiamond particles, CNTs, graphene, carbon dots, hydrotalcite, manganese dioxide, and composites for various applications, such as supercapacitors, coatings for corrosion protection of metals, and sensors. [ 95,96,98–100 ]…”

“…BSs facilitated the solubilization of water‐insoluble drugs in water and allowed for the EPD of composite coatings for drug delivery [96a,101] . Sodium cholate was used as a charged dispersant for the EPD of polymethylmethacrylate (PMMA) and composite PMMA–alumina films for biomedical applications.…”
