“…Owing to the adjustability of the intercommunicating networks of hydrogels, they are attractive for loading antibacterial agents with various molecular weights and physiochemical properties and sustaining their release around the implantation site [ 25 , 28 ]. Among the biopolymers used in the formation of hydrogels, biologically relevant materials, including collagen, gelatin, hyaluronic acid, chitosan, and alginate, are widely used owing to biodegradability, safety, and their capabilities of inducing cell adhesion, growth, and differentiation [ 28 , 81 , 82 ]. Among previous studies, Wu et al [ 83 ] reported on utilizing binary combinations of chitosan and gelatin for producing hydrogel coatings on Ti implants, facilitating bone cell adherence and growth.…”
