“…The fabricated PVA-Tyr/Col fibrous exhibited characteristic bands of PVA-Tyr and Col (Figure 3(b)). [33][34][35] The peaks of PVA-Tyr demonstrated by the peaks 3435 cm À1 indicates the presence of O-H group with polymeric association and N-H stretching of secondary amide and peaks at 2932 cm À1 and 2872 cm À1 related to asymmetric and symmetric CH 2 stretching respectively. It also shows a peak at 1634 cm À1 carbonyl stretching, 1248 cm À1 C-O and C-C stretching, 1102 cm À1 symmetric C-O-C stretching.…”

Biocompatible electrospun fiber comprising bioactive substrates has potential to implant into the wound site as a reliable therapeutic approach in tissue regeneration. Here, electrospun polyvinyl alcohol conjugated tyramine (PVA-Tyr) and collagen (Col) fibrous mat containing chitosan nanoparticle loaded with epigallocatechin 3-gallate (NCs-EGCG) developed and the composite was applied to evaluate in vivo wound healing ability of fabricated wound patch. The synthesized PVA-Tyr and Col were electrospun and crosslinked through peroxidase reaction in presence of vaporized H2O2 as an electron donor which covalently proceeded conjugation of phenolic groups and could develop hybrid fibrous mat in stable structure and uniform shapes. The EGCG as anti-oxidative/inflammatory substrate was encapsulated efficiently in NCs and released in a sustained manner. The hybrid fibers seeded with adipose-derived stem cells presented appropriate biocompatibility from biophysical and biochemical viewpoints and in following wound healing ability in a full-thickness excisional animal model. Fourier transform infrared spectroscopy (FTIR) confirmed all typical absorption characteristics of PVA-Tyr and Col as well as NCs and EGCG. The results showed the perfect hydrophilic/hydrophobic ratio and good mechanical and structural characteristics including shape uniformity and porosity. Interestingly, cellular attachment and proliferation on the PVA-Tyr/Col fibers containing NCs-EGCG were higher than control samples. The histological analysis of hybrid fibrous patch could be suggested the applicability of this structure as suitable skin substitutes to repair injured skin.

“…The PVA/collagen blend gave a strong -O–H stretching band, very weak amide I and II band and the shift of −O-Hstretch to a lower position from 3304 to 3280 cm –1 indicated that the occurrence of cross-linking between hydroxyl groups of PVA with the amide group of collagen might be through a hydrogen bond. 10 , 33 …”

“…By blending collagen with PVA, weak properties of collagen such as poor mechanical strength and fast biodegradation rate could be overwhelmed. 10 The pigment responsible for tanning of the skin is melanin, though it helps in protecting the skin from UV-induced DNA degradation, the abnormal accumulation of melanin due to higher tyrosinase activity results in uneven patches on the skin causing an aesthetic problem. Therefore, natural tyrosinase inhibitor curcumin is one of the choices as a skincare ingredient in cosmetic products.…”

Fabrication and Determination of the Sun Protection Factor and Ultraviolet Protection Factor for Piscean Collagen/Bischalcone Derivative (B1) Composite Films with Wide-Range UV Shielding

The present study investigates the development of distinct UV-A and UV-B radiation filtering materials through the introduction of a heterocyclic bischalcone derivative [(3,5-bis{[4-(methylsulfanyl)phenyl]methylidene}piperidin-4-one] ( B1 ) into the matrix of PVA/Piscean collagen blend films (1:1) prepared through the solution casting method and characterized. The dopant concentration varied from 0.25 to 4%. The scanning electron microscopy images showed the rough surface due to the uniform dispersion of dopant B1 . The addition of different concentrations of B1 altered the mechanical strength with a proportional increase in Young’s modulus (146–317 MPa), tensile strength (23.3–39.21 MPa), and decrease in its elongation at break (158.8–105.2%). As the dopant B1 belongs to the bischalcone class of compounds which absorb in the UV–vis region (370 nm λ max ) due to the α, β unsaturated keto group, it was selected for doping. Dopant concentration-dependent increase in density was observed in films (31–162 mg/cm 3 ). The bathochromic shift in UV absorption from 370 to 390 nm for λ max as well as hyperchromism was evidenced with proportional increase in the concentration of B1 , indicating its capacity to block UV rays. On determining the UV filtering ability for all the prepared films, the one with 4% dopant showed a higher sun protection factor (SPF) with a value of 27.53 and ultraviolet protection factor (UPF) with a value of 58.23. In addition, the degradation of supercoiled PBR322 DNA on UV irradiation was effectively inhibited by these films with a dopant concentration of 0.5–4.0%, which might cause less harm to the skin. The inferences of the experiments would indicate the use of these water-insoluble films as UV blocking potential materials with a merit of SPF and UPF characteristics.

The Collagen Suprafamily: From Biosynthesis to Advanced Biomaterial Development

Collagen is the oldest and most abundant extracellular matrix protein that has found many applications in food, cosmetic, pharmaceutical, and biomedical industries. First, an overview of the family of collagens and their respective structures, conformation, and biosynthesis is provided. The advances and shortfalls of various collagen preparations (e.g., mammalian/marine extracted collagen, cell‐produced collagens, recombinant collagens, and collagen‐like peptides) and crosslinking technologies (e.g., chemical, physical, and biological) are then critically discussed. Subsequently, an array of structural, thermal, mechanical, biochemical, and biological assays is examined, which are developed to analyze and characterize collagenous structures. Lastly, a comprehensive review is provided on how advances in engineering, chemistry, and biology have enabled the development of bioactive, 3D structures (e.g., tissue grafts, biomaterials, cell‐assembled tissue equivalents) that closely imitate native supramolecular assemblies and have the capacity to deliver in a localized and sustained manner viable cell populations and/or bioactive/therapeutic molecules. Clearly, collagens have a long history in both evolution and biotechnology and continue to offer both challenges and exciting opportunities in regenerative medicine as nature's biomaterial of choice.
