Summary

Traditional medical polymer materials have certain disadvantages associated with poor mechanical properties, biocompatibility, biodegradability, and weak antibacterial ability, which makes it unsuitable for biomedical field. For this reason, it is imperative to develop the ideal biomedical materials based on natural biopolymers with multi-functional advantages such as softness, breathability, flexibility, transparency, free formability, antibacterial properties and underpinning all these properties. Polysaccharides and gelatin are the most abundant natural biopolymers with low cost, good properties (e.g., film-forming, biodegradable and biocompatible), which can be used to propose rational solutions. This special collection aims to focus on areas related to biopolymers technologies, science, and functionalization, and their potential use in biomedical applications, such as antibacterial materials, drug-carrier, tissue engineering. It will cover biopolymers preparation, characterization, performance, and application evaluation. Potential topics include but are not limited to the research areas above. Other sub-topics as long as they align with the general theme of the Special Issue are also encouraged. The original research articles, review/mini-review articles, and case studies are welcome.

    Effect of PEG Incorporation on Physicochemical and in vitro Degradation of PLLA/PDLLA Blends: Application in Biodegradable Implants

    Abstract Polyethylene glycol (PEG) was added at different concentrations to the blend of poly(L-lactic acid) (PLLA) and poly(D,L-lactic acid)(PDLLA) to tailor the properties. The differential scanning calorimetry (DSC) measurement showed that all blends were miscible due to shifting a single glass transition temperature into a lower temperature for increasing PEG content. The DSC, FTIR, and XRD results implied the crystallinity enhancement for PEG content until 8 wt%, then decreased at 12 wt% PEG. The XRD result indicated the homo crystalline phase formation in all blends and no stereocomplex crystal. The in vitro degradation study indicated that PEG content is proportional to… More >

    Abstract This study aimed to characterize the physical-chemical and biological properties of pectin (PC)/chia seed mucilage (CM) membranes. PC/CM [100/0 (control), 80/20%, 60/40%, and 40/60% w/w] membranes were prepared using the casting method. The membranes (PC/CM) were thin, yellow, lightly opaque (≈10%) and capable of blocking light UVB (between 66 at 52%). SEM analysis showed the presence of aggregates in the shape of a sphere (≈13 µm) and ovoid (≈25 µm). The proportion of 80/20 showed an increase in tensile strength (29%) and elastic modulus (19%) when compared to the control. FTIR analysis exhibited intermolecular interactions between PCPC, PC-CM, and CM-CM… More >

    Construction of Customized Bio Incubator and Designing of Tailored Scaffolds for Bone Tissue Engineering from Laboratory Scale Up to Clinical Scale

    Soliman Abdalla, Shiref Kandil

    Abstract In order to obtain larger, clinical-scale and practical-scale bone grafts, we have designed both tailored scaffolds and tailored bio incubator with optimal bio-production characteristics. Using DIC files to Simpleware Scan-IP (Simple-ware-exeter United Kingdom), we have digitally reconstructed segmental additive bone-tissue in order to perform images processing. Both hydroxyapatite and tannin composites have been used in order to get the final bone modules combined for retexturing of segmental bone defect. We have found that sectioning of bone segment deficiency reorganizations into well disk-shaped design permits one to standardize the cell culture and seeding protocol, to get better products.
