“…As the X‐ray scattering profile demonstrates, hydrogen peroxide increases the cellulose crystallinity while ethanol does not affect the crystallinity. A coagulation agent in the form of an alcohol induces changes in the protein β‐sheet formation as previously demonstrated . In continuation with the silk/cellulose biocomposites, attention is attracted to the morphological effect as a function of coagulation agent and type of ionic liquid with various correlation distances.…”

The relationship between morphology and the ionic conductivity of polysaccharide–protein bio‐electrolyte membranes is explored in this study. Structural proteins and polysaccharides form hydrophobic and electrostatic interactions, and the resulting matrices can exhibit novel and useful properties. However, transforming these natural biomacromolecules from their native state to a more usable form is challenging. The structural, morphological, thermal, mechanical and electrical properties of biomaterials composed of microcrystalline cellulose and Bombyx mori silk when regenerated together using ionic liquids and various coagulation agents were investigated using a diverse set of techniques including Fourier transform infrared spectroscopy, SEM, TGA, DSC, X‐ray scattering, AFM‐based nanoindentation and dielectric relaxation spectroscopy. The surface topography of the films reveals morphological changes with varying coagulation agents and ionic liquids. It was found that the thermal and mechanical properties were dependent on intermolecular interactions dictated by the type of ionic liquid used during the coagulation process. X‐ray scattering provided information on how the cellulose crystallinity varied with coagulation agent. Specifically, samples coagulated with hydrogen peroxide showed an increase in cellulose crystallinity impacting properties such as elasticity, hardness and ionic conductivity of the biocomposites. In addition, the results revealed a strong correlation between β‐sheet content and ionic conductivity and cellulose crystallinity. The results provided evidence that the ionic conductivity is dependent on protein β‐sheet content and cellulose crystallinity. © 2019 Society of Chemical Industry

“…As previously stated above, this structure allows for a wide range of possibilities in forming composites [23]. DeFrates et al and Stanton et al describe the dissolution process for creating a cellulose-silk composite [22,23,108]. The dissolution process occurs by the ionic liquid's anion attaching to the hydroxyl groups in order to form hydrogen bonds, which disrupts the natural hydrogen network.…”

“…After dissolution, the cellulose becomes disordered and extends its fibrils for silk molecules to attach to and create the composite. It will retain its cellulose crystallinity property but have interspersed silk molecules [108]. After dissolution is complete, the composite is coagulated with water or methanol to form a biofilm [22].…”

Protein–polysaccharide composites have been known to show a wide range of applications in biomedical and green chemical fields. These composites have been fabricated into a variety of forms, such as films, fibers, particles, and gels, dependent upon their specific applications. Post treatments of these composites, such as enhancing chemical and physical changes, have been shown to favorably alter their structure and properties, allowing for specificity of medical treatments. Protein–polysaccharide composite materials introduce many opportunities to improve biological functions and contemporary technological functions. Current applications involving the replication of artificial tissues in tissue regeneration, wound therapy, effective drug delivery systems, and food colloids have benefited from protein–polysaccharide composite materials. Although there is limited research on the development of protein–polysaccharide composites, studies have proven their effectiveness and advantages amongst multiple fields. This review aims to provide insight on the elements of protein–polysaccharide complexes, how they are formed, and how they can be applied in modern material science and engineering.

“…The hydrophilic amino acids in the structure of silk provide its elasticity [17,37,38]. Crystallinity of the β sheet can be tuned by methanol treatments in order to modify its mechanical properties [39,40]. The most extensively studied and utilized silk comes from the domestic silkworm, Bombyx mori, due to its large-scale production and its biocompatibility.…”

The combination of protein and polysaccharides with magnetic materials has been implemented in biomedical applications for decades. Proteins such as silk, collagen, and elastin and polysaccharides such as chitosan, cellulose, and alginate have been heavily used in composite biomaterials. The wide diversity in the structure of the materials including their primary monomer/amino acid sequences allow for tunable properties. Various types of these composites are highly regarded due to their biocompatible, thermal, and mechanical properties while retaining their biological characteristics. This review provides information on protein and polysaccharide materials combined with magnetic elements in the biomedical space showcasing the materials used, fabrication methods, and their subsequent applications in biomedical research.
