Special Issue Information

Dear Colleagues,

The demand for green products and environmentally friendly processes has focused the increasing attention of the research community on the use and valorization of renewable resources. Biopolymers are obvious actors of this revolution, since they substitute limited or fossil resources with materials of biological origin. Cellulose, lignin, alginate, and chitin (or their derivatives) are emblematic examples of biopolymer that are progressively gaining more importance in industrial processes; academic research trends based on these materials are following the same “blowing” growth.

The chemical and physical versatilities of these materials, which can be readily modified and shaped under different forms, are opening more and more research areas for applications in health, biological, biomedical, pharmaceutical, cosmetics, environmental, agriculture, chemistry, textile, and energy applications.

The development of these themes requires the complementary contributions of fundamental knowledge (material sciences) and expertise in processing (chemical engineering). The vocation of this Special Issue “Biopolymer and their Applications” is to contribute to reinforcing this cross-sectional approach.

Bringing a better understanding of the effect of the variability of the primary resource on the characteristics of the biopolymer-based materials would help in expanding their application to industry. Harnessing the attention of readers of original and advanced new materials would fertilize this research area. Understanding the impact of structural parameters on their applied performances is also an attractive challenge for boosting their development.

We would like to invite you to contribute to this project by submitting reviews, articles, or letters. Please help make this project a success by contributing to the development of biopolymer applied research.

Collagen/Polyethylene Oxide Nanofibrous Membranes with Improved Hemostasis and Cytocompatibility for Wound Dressing

As a promising agent for biomedical application, collagen has been used as a nanofiber to architecturally mimic its fibrillar structure in Extracellular Matrix (ECM); however, it has to be modified by techniques, such as crosslinking, to overcome its limitations in structural stability along with potential toxicity. Here, we prepared collagen/polyethylene oxide (PEO) nanofibrous membranes with varying crosslinking degrees and their properties, such as water stability, mechanical properties, blood clotting capacity and cytocompatibility, were studied systematically. By investigating the relationship between crosslinking degree and their properties, nanofibrous membranes with improved morphology retention, blood clotting capacity and cytocompatibility have been achieved. The result of circular dichroism measurement demonstrated that a triple helical fraction around 60.5% was retained. Moreover, the electrospun collagen/PEO at crosslinking degrees above 60.6% could maintain more than 72% of its original weight and its nanofibrous morphology under physiological conditions could be well preserved for up to 7 days. Furthermore, the crosslinked collagen/PEO membrane could provide a more friendly and suitable environment to promote cell proliferation, and about 70% of the clot can be formed in 5 min. With its superior performance in water stability, hemostasis and cytocompatibility, we anticipate that this nanofibrous membrane has great potential for wound dressing. Full article

Three-dimensional (3D) bioprinting technology is now one of the best ways to generate new biomaterial for potential biomedical applications. Significant progress in this field since two decades ago has pointed the way toward use of natural biopolymers such as polysaccharides. Generally, these biopolymers such as alginate possess specific reactive groups such as carboxylate able to be chemically or enzymatically functionalized to generate very interesting hydrogel structures with biomedical applications in cell generation. This present review gives an overview of the main natural anionic polysaccharides and focuses on the description of the 3D bioprinting concept with the recent development of bioprinting processes using alginate as polysaccharide.

Lignocellulose feedstock (LCF) provides a sustainable source of components to produce bioenergy, biofuel, and novel biomaterials. Besides hard and soft wood, so-called low-input plants such as Miscanthus are interesting crops to be investigated as potential feedstock for the second generation biorefinery. The status quo regarding the availability and composition of different plants, including grasses and fast-growing trees (i.e., Miscanthus, Paulownia), is reviewed here. The second focus of this review is the potential of multivariate data processing to be used for biomass analysis and quality control. Experimental data obtained by spectroscopic methods, such as nuclear magnetic resonance (NMR) and Fourier-transform infrared spectroscopy (FTIR), can be processed using computational techniques to characterize the 3D structure and energetic properties of the feedstock building blocks, including complex linkages. Here, we provide a brief summary of recently reported experimental data for structural analysis of LCF biomasses, and give our perspectives on the role of chemometrics in understanding and elucidating on LCF composition and lignin 3D structure.
