In this study, we present an innovative research within the intersection of biotechnology, materials science, and electronics by presenting an approach to enhance the electrical characteristics of silk fibers. By feeding silkworms with mulberry leaves infused with reduced graphene oxide (rGO), we achieved the integration of the nanomaterial into the biopolymer matrix of silk fibers. Through comprehensive spectroscopic analyses, including Fourier transform infrared (FTIR) and Raman spectroscopy, we confirmed the incorporation of rGO into the silk fiber structure. Key findings emphasize a significant hydrogen interaction between the hydroxyl groups of rGO and the NH groups of silk. This molecular interaction not only bolsters the conductivity of the fibers but also maintains the natural silk's coloration. Electrical characterization revealed a temperature-dependent conductivity pattern. Significantly, this behavior adheres to the variable range hopping (VRH) formalism, suggesting a T ( ) 1/4 temperature relationship. Notably, a conductivity of approximately σ =4 × 10 −3 S/m was achieved in the modified fibers. This study represents a significant advancement in the innovation of electronic textiles by enhancing the electrical properties of silk fibers. The introduction of nanomaterial opens new opportunities for its implementation in the field of smart textiles, providing improved electronic properties that have the potential to transform the apparel industry.

“…Bombix mori caterpillar cocoons are used to make silk fiber [35,92]. Due to its high tensile strength, strong degree of resilience, elasticity, flexibility, biodegradation, and great biocompatibility, it is considered a possible biomaterial that supports cell attachment and proliferation [92][93][94][95][96][97][98]. Silk fibers are strong, smooth and crease resistant, with a high capacity to absorb water.…”

Asian countries have abundant resources of natural fibers, but unfortunately, they have not been optimally utilized. The facts showed that from 2014 to 2020, there was a shortfall in meeting national demand of over USD 2.75 million per year. Therefore, in order to develop the utilization and improve the economic potential as well as the sustainability of natural fibers, a comprehensive review is required. The study aimed to demonstrate the availability, technological processing, and socio-economical aspects of natural fibers. Although many studies have been conducted on this material, it is necessary to revisit their potential from those perspectives to maximize their use. The renewability and biodegradability of natural fiber are part of the fascinating properties that lead to their prospective use in automotive, aerospace industries, structural and building constructions, bio packaging, textiles, biomedical applications, and military vehicles. To increase the range of applications, relevant technologies in conjunction with social approaches are very important. Hence, in the future, the utilization can be expanded in many fields by considering the basic characteristics and appropriate technologies of the natural fibers. Selecting the most prospective natural fiber for creating national products can be assisted by providing an integrated management system from a digitalized information on potential and related technological approaches. To make it happens, collaborations between stakeholders from the national R&D agency, the government as policy maker, and academic institutions to develop national bioproducts based on domestic innovation in order to move the circular economy forward are essential.

“…An excellent property that this silk fibroin material possesses is the ability to be processed into solution form and then formed into various assemblies like the electrospun nanofibrous mat and films with controlled thickness (up to 125 nm has been achieved). This processing goes through the washing of silk fiber, obtained after reeling it from the silkworm cocoons, by methods like water boiling, soap solution, alkali treatment, acid treatment, pressurized steam, organic amines, or enzyme treatment, − to remove the sericin and thus to separate the filaments that it holds. These filaments are then subjected to dissolution using a solvent system containing solvents like lithium bromide, trifluoroacetic acid, and formic acid, which are then regenerated into desired final forms.…”

The development of flexible, biocompatible, and environmentfriendly sensors has attracted a significant amount of scientific interest for the past few decades. Among all the natural materials, silk fibroin (SF), due to its tunable biodegradability, biocompatibility, ease of processing, presence of functional groups, and controllable dimensions, has opened up opportunities for immobilizing multitudinous biomolecules and conformability to the skin, among other attractive opportunities. The silk fibroins also offer good physical properties, such as superior toughness and tensile strength. The sensors made of SF as an immobilization matrix have demonstrated excellent analytical performance, sensing even at low concentrations. The significant advantage of silk fibroins is the presence of functional groups along with a controllable conformation transition that enables immobilization of receptor molecules using silk fibroins as an immobilization matrix enables us to entrap the receptor molecules without using any chemical reagents. This review encompasses a detailed discussion on sensors, the advantages of using silk fibroins as an immobilization matrix for various receptors, their applications, and the future research scope in this state-of-the-art technology based upon the explorable applications for silk fibroin-based sensors.
