Biopolymer coating for particle surface engineering and their biomedical applications

Balance between the CMC/ACP Nanocomplex and Blood Assimilation Orchestrates Immunomodulation of the Biomineralized Collagen Matrix

“…Moreover, the surface functionalization method also showed application prospects. Protein-based coating and biopolymers such as chitosan and cellulose generally have ideal biocompatibility, cell adhesion performance, and degradability. , Together with inorganic scaffolds, these surface-functionalized materials have the potential to block the factors that trigger inflammation while retaining the mechanical advantages of inorganic scaffolds.…”

Macromolecular Modification Strategies for Biomaterial Surface: Challenges in Fundamental Research and Applications

“…Moreover, proteins, such as albumin and lysozyme, can form versatile coatings by multivalent binding interactions with the substrate. The abundant amino and carboxyl groups in proteins provide the possibility for subsequent functional modifications. − Similarly, microgels with topological structures and film-forming properties have also been used for the modification of complex surfaces. − These macromolecular modification strategies provide innovative solutions for the construction of biomaterial surfaces with more complex structures and more demands in safety, functionality, and application conditions. Particularly, distinct from surface modification of conventional biomaterials, the painting of macromolecules on the surfaces of bacteria and cells is becoming a reality.…”

Polymer Coated Functional Catalysts for Industrial Applications

“…Polysaccharides, namely, chitosan, cellulose, and polyphenol derivatives, such as polydopamine (PDA), tannic acid (TA), and proteins, are the naturally occurring polymers that have been used as coating material. Particularly, the biopolymers that are widely employed as surface modification agents of catalysts include PDA, TA, and protein amyloid-like aggregates that have the ability to naturally adhere to the particle surface and form a conformal coating layer [51]. PDA-coated anodic alumina membranes impregnated with silver nanoparticles and PDOP-coated polystyrene (PS) nanotubes with highly active silver nanoparticles were used for the reduction of aromatic nitro compounds [52].…”

“…The disadvantages of non-biodegradability and undesirable biocompatibility have paved the path for the development of biopolymeric coatings for catalysts. Natural polysaccharide polymers (chitosan and cellulose), polyphenol-based biopolymers (polydopamine and tannic acid), and proteins have been used in the surface modification of particles [51]. A one-pot synthesis method of 10-20 nm sized chitosan (CS)-coated copper oxide nano electrocatalysts were prepared for CO 2 reduction in aqueous media and the coated catalyst successfully retarded the hydrogen evolution reaction [15].…”
