“…The preparation of powdered silk directly from silk fibers can be commonly made using chemical processes, being a very difficult task to accomplish due to silk's flexibility and high mechanical strength. An alternative approach to produce silk particles is to use silk fibers directly, avoiding the use of chemicals . Kazemimostaghim et al proposed a method to prepare submicron‐sized silk particles using a combination of attritor milling and bead milling processes with optimized milling speed, slurry concentration, milling time, pH, and drying methods.…”

Designing novel multifunctional materials from natural resources is a challenging goal that has increasingly attracted researchers. Recently, the great potential of silk fibers has been recognized. The target readers for this review are researchers from different backgrounds (i.e., non‐specialists in silk research) with special interests on the physical–chemical characterization of silk fibers, since their knowledge is crucial for the improvement of existent silk‐based biomaterials and the basis for the development of new products. Examples of usual applications of Bombyx mori silk fibers are given and some of the most recent and exciting progress in new technological fields, is presented.

“…Rough morphology and the ultrafine particle size result in the increased enzymatic degradation, as compared to raw fibers . Particles obtained by attritor–bead mill combination with alkaline charge repulsion and surfactant repulsion methods possessed an evidence of amorphous content reduction, increase in surface area, and also reduction in crystallinity . Alternatively, particles can be formulated using an emulsion method with PVA as emulsifier.…”

For years, silk fibroin of a domestic silkworm, Bombyx mori, has been recognized as a valuable material and extensively used. In the last decades, new application fields are emerging for this versatile material. Those final, specific applications of silk dictate the way it has been processed in industry and research. This review focuses on the description of various approaches for silk downstream processing in a laboratory scale, that fall within several categories. The detailed description of workflow possibilities from the naturally found material to a finally formulated product is presented. Considerable attention is given to (bio‐) chemical approaches of silk fibroin transformation, particularly, to its enzyme‐driven modifications. The focus of the current literature survey is exclusively on the methods applied in research and not industry.

“…In contrast to bottom-up approaches, we have shown that native crystalline structure of silk fibres can be retained if top-down approach of milling is used for particle production [37]. In milling methods, fibres are processed through different types of milling systems to achieve a desirable particle size [38].…”

“…We have reported the production of micron and submicron silk particles using different milling approaches [39,40]. It was observed that submicron silk particles had almost similar β structure, thermal properties, and crystallinity to that of silk fibres [37]. Particles produced from the solution method and the milling method were also compared [41].…”
