“…The antibacterial and UV protection properties of the loaded fabrics were affected by the nature of the extract from the different sources. In addition, anthocyanins in black rice aqueous extracts were responsible for the reduction and stabilization of the produced AgNPs on cotton surfaces . The reduction of Ag + to Ag o and formation of AgNPs were reported at pH 10 with the anthocyanin compounds present in the black rice extract.…”

Tremendous progress has been made in developing highly efficient cutting-edge materials and textile surfaces by applying a wide range of nanostructures during the past few years. Due to their extraordinary and attractive features, metal and metal oxide nanoparticles (NPs) have introduced prominent novel antimicrobial, photocatalytic, stain repellence, fire retardant, and UV protective functions on textile surfaces. Unfortunately, their conventional syntheses based on physicochemical procedures often require energy-intensive processes and toxic chemicals, bringing environmental and human safety concerns. To address these issues, the latest approaches based on the biological production of NPs on polymeric material surfaces are currently being pursued. In this perspective, we present a systematic and comprehensive summary of the biological in situ and ex situ formation of metallic NPs on the surfaces of textiles and fibers. A detailed and insightful discussion on the ex situ and in situ mechanisms of nanoparticle formation from chemical compounds derived from plants and fungi is also provided. Finally, critical research gaps are identified, and prospects for efficient and sustainable nanofinishing technologies for textile surfaces using biological chemicals are provided.

“…Another interesting example of impregnation of Ag NPs onto a fabric surface by dipping is due to He's group [27]. The cotton fabric was first padded with a solution of carboxymethylchitosan and then soaked in a solution of silver nitrate and black rice extracts (reductant).…”

Recent Advances on Antimicrobial and Anti-Inflammatory Cotton Fabrics Containing Nanostructures

Hydrophilic cotton textiles, used in hospitals and sportswear, are prone to the growth of microorganisms (bacteria, fungi) resulting in hygiene and health risks. Thus, healthcare concerns have motivated the interest for the development of multifunctional antimicrobial cotton fabrics. Moreover, cotton textiles are also used in medical applications such as wound dressings. Their functionalization with anti-inflammatory agents is desirable in order to accelerate cicatrisation in the treatment of chronic wounds. This review summarizes recent advances (from January 2016 to January 2021) on the modification and coating of cotton fabrics with nanostructures (mainly metal and metal oxide nanoparticles, functionalized silica nanoparticles) to provide them antimicrobial (antibacterial and antifungal) and anti-inflammatory properties.

“…In particular, bottom-up wet-chemical processes represent the most widespread technique, generally relying upon mild operative conditions. Among them, eco-friendly reactants 21 can be adopted to synthesize elemental Ag NPs using several non-toxic reductants such as plant extracts, 22 yeasts 23 and fungi. 24 Promising results have been obtained using microorganisms 25 as nanofactories for the preparation of Ag NPs, 26 but these methods often require post-treatments to set Ag NPs free from unwanted products of biological origin.…”
