“…Recently, the antibacterial, mechanical, and physical properties of a collagen-chitosan sponge scaffold, constructed from aquatic sources, were studied [ 56 ]. The researcher applied the lyophilisation technique (−50 °C, 0.5 Mbar vacuum pressure) to acquire a highly porous-structured scaffold.…”

Scaffolds support and promote the formation of new functional tissues through cellular interactions with living cells. Various types of scaffolds have found their way into biomedical science, particularly in tissue engineering. Scaffolds with a superior tissue regenerative capacity must be biocompatible and biodegradable, and must possess excellent functionality and bioactivity. The different polymers that are used in fabricating scaffolds can influence these parameters. Polysaccharide-based polymers, such as collagen and chitosan, exhibit exceptional biocompatibility and biodegradability, while the degradability of synthetic polymers can be improved using chemical modifications. However, these modifications require multiple steps of chemical reactions to be carried out, which could potentially compromise the end product’s biosafety. At present, conducting polymers, such as poly(3,4-ethylenedioxythiophene) poly(4-styrenesulfonate) (PEDOT: PSS), polyaniline, and polypyrrole, are often incorporated into matrix scaffolds to produce electrically conductive scaffold composites. However, this will reduce the biodegradability rate of scaffolds and, therefore, agitate their biocompatibility. This article discusses the current trends in fabricating electrically conductive scaffolds, and provides some insight regarding how their immunogenicity performance can be interlinked with their physical and biodegradability properties.

“…In the process of extracting collagen, the assembly structure and natural cross-linking are often destroyed, weakening its mechanical strength, thermal stability, and enzyme resistance [ 8 ]. In addition, collagen does not have antibacterial and hemostatic effects, so it needs to be combined with other biopolymers, nano-particles, or drugs to improve its shortcomings [ 43 ]. The mechanical properties of collagen composite membranes can be reinforced by chitosan and beta-tricalcium phosphate [ 44 ].…”

This literature review provides an overview of the fabrication and application of biopolymer hybrid particles in dentistry. A total of 95 articles have been included in this review. In the review paper, the common inorganic particles and biopolymers used in dentistry are discussed in general, and detailed examples of inorganic particles (i.e., hydroxyapatite, calcium phosphate, and bioactive glass) and biopolymers such as collagen, gelatin, and chitosan have been drawn from the scientific literature and practical work. Among the included studies, calcium phosphate including hydroxyapatite is the most widely applied for inorganic particles used in dentistry, but bioactive glass is more applicable and multifunctional than hydroxyapatite and is currently used in clinical practice. Today, biopolymer hybrid particles are receiving more attention as novel materials for several applications in dentistry, such as drug delivery systems, bone repair, and periodontal regeneration surgery. The literature published on the biopolymer gel-assisted synthesis of inorganic particles for dentistry is somewhat limited, and therefore, this article focuses on reviewing and discussing the biopolymer hybrid particles used in dentistry.

“…It could be that the antimicrobial activity of collagen is inherently weaker than that of sericin and chitosan. 21 The mechanism of the antibacterial activity of the immobilized agent is speculated to be based on two factors. On the one hand, the active portion of biomolecules bounded to the PP fabric adsorbed the electronegative cell wall of bacteria, which could agglomerate them.…”

In order to realize the immobilization of collagen, chitosan and sericin on the surface of polypropylene fabric, the fabric is treated by ammonia and nitrogen low temperature plasma to produce reactive groups, and then the epoxy compounds (ethylene glycol diglycidyl ether, trimethylolpropane triglycidyl ether) are used as crosslinkers for a bridging process. Single factor experiment is carried out to investigate the influence of crosslinking parameters (temperature, time and the dosage of crosslinker) on immobilization yield. Chemical composition changes on the surface of the treated samples is analyzed by infrared spectroscopy, which indicated that the ammonia plasma treatment can produce more active groups. The results showed that immobilization rate of samples crosslinked by ethylene glycol diglycidyl ether is superior to that of trimethylolpropane triglycidyl ether. It also can be found that the fabric had a better wettability and antimicrobial properties. The whiteness and comfort property of chitosan-polypropylene fabric decreased slightly.
