“…Therefore, bactericidal properties can be enhanced by introducing more Ag into the cotton surface. [25][26][27][28][29] It is believed that metallic Ag 0 NPs exhibit similar mechanisms to Ag ions by generating a redox inequality that leads to an broad bacterial death. It was demonstrated that release of Ag was controlled by an oxidation process at the NP surface that prevents loss of Ag NPs from the cotton surface.…”

“…Upon irradiation of Ag NPs using UV rays, an electron from the valence band can be induced to the conductive band to generate pairings of positive holes and negative electrons. [25,26] These active species display a major role in the initiation of the oxidation/reduction process. Ag NPs have been considered in photocatalysis under UV irradiation due to their availability, nontoxicity, physical and chemical stability, low cost, and optical properties.…”

Smart textiles with a multifunctional surface, such as with photoluminescence, antimicrobial, and superhydrophobic properties, are highly desirable. Silver nanoparticles (Ag NPs) were prepared and immobilized onto a cotton surface using a facile pad-dry-curing technique to introduce long-lasting antimicrobial properties. The morphology of the silver immobilized cotton fibres was explored using scanning electron microscopic images and energy-dispersive X-ray spectra. The morphology of the formed Ag NPs was determined using a transmission electron microscope. Ag NPs exhibited uniform spreading and a high deposition density with a particle diameter in the range 25-55 nm. Both photoluminescence and superhydrophobic properties were explored by studying the cotton samples treated with hexadecyltrimethoxysilane nanocomposite containing lanthanide-doped strontium oxide aluminate NPs. Ultraviolet-visible light absorption, phosphorescence, and lifetime spectra were measured. The produced transparent superhydrophobic and photoluminescent film showed two absorbance bands at 273 and 367 nm and emission bands at 415 and 437 nm, as recognized by both absorption and emission spectra. Excellent antibacterial activities towards E. coli and S. aureus were monitored for the coated samples. Both fastness and colorimetric properties of Ag NPs-coated fabrics were explored.

Nanotechnology has transformed the world with its diverse applications, ranging from industrial developments to impacting our daily lives. It has multiple applications throughout financial sectors and enables the development of facilitating scientific endeavors with extensive commercial potentials. Nanomaterials, especially the ones which have shown biomedical and other health‐related properties, have added new dimensions to the field of nanotechnology. Recently, the use of bioresources in nanotechnology has gained significant attention from the scientific community due to its 100 % eco‐friendly features, availability, and low costs. In this context, jute offers a considerable potential. Globally, its plant produces the second most common natural cellulose fibers and a large amount of jute sticks as a byproduct. The main chemical compositions of jute fibers and sticks, which have a trace amount of ash content, are cellulose, hemicellulose, and lignin. This makes jute as an ideal source of pure nanocellulose, nano‐lignin, and nanocarbon preparation. It has also been used as a source in the evolution of nanomaterials used in various applications. In addition, hemicellulose and lignin, which are extractable from jute fibers and sticks, could be utilized as a reductant/stabilizer for preparing other nanomaterials. This review highlights the status and prospects of jute in nanotechnology. Different research areas in which jute can be applied, such as in nanocellulose preparation, as scaffolds for other nanomaterials, catalysis, carbon preparation, life sciences, coatings, polymers, energy storage, drug delivery, fertilizer delivery, electrochemistry, reductant, and stabilizer for synthesizing other nanomaterials, petroleum industry, paper industry, polymeric nanocomposites, sensors, coatings, and electronics, have been summarized in detail. We hope that these prospects will serve as a precursor of jute‐based nanotechnology research in the future.

This article summarizes the preparation and applications of carbon derived from jute sticks and fibers that are low‐cost, widely available, renewable, and environmentally friendly. Both the fibers and sticks are considered ideal candidates of carbon preparation because they are composed of cellulose, hemicelluloses, and lignin, and contain negligible ash content. Various carbon preparation methods including simple pyrolysis, pyrolysis with chemical and physical activations are discussed. The impacts of several parameters including types of activating agents, impregnation ratio, and temperature on their morphology, surface area, pore size, crystallinity, and surface functional groups are also emphasized. Various treatments to endow functionalization for increasing the practical applicability, such as chemical, physical, and physico‐chemical methods, are discussed. In addition, applications of jute‐derived carbon in various practical areas, including energy storage, water treatment, and sensors, are also highlighted in this report. Due to the porous fine structure and a large specific surface area, the jute‐derived carbon could be considered as a powerful candidate material for various industrial applications. Finally, possible future prospects of jute‐derived carbon for various applications are pointed out.
