Facile and efficient dye degradation using silver nanoparticles immobilized cotton substrates

Controlled Growth of Silver Nanoparticles on Cotton Substrate for Enhanced SERS, Catalytic, and Antibacterial Performance

“…Cotton stands out as a cost‐effective and readily available material, making it an economical choice for large‐scale catalytic applications [29] . The inherent porosity of cotton provides a larger surface area, ideal for NPs growth/deposition, facilitating efficient catalytic reactions [2] . A cotton‐based substrate holds significant promise for SERS applications due to its 3D nature, allowing for the acquisition of SERS signals not only from the surface but also from the depth of the substrate [30,31] .…”

“…Silver NPs have diverse applications spanning multiple industries, including sensors, catalysis, and antibacterial agents [1–5] . Their versatility arises from their inherent cost‐effectiveness, remarkable SERS activity, and excellent catalytic and antibacterial properties.…”

“…This can offer additional advantages, including the ability of swab‐based SERS for trace detection applications, facile recovery and reusability for catalytic applications, and wound dressing for bacterial protection. Various techniques, such as dip and ultra‐sonication processes, [20] chemical reduction, [2] Layer‐by‐layer deposition, [21] Microwave‐assisted synthesis, [22] pen‐on‐paper approach, [23] immersion deposition, [24] inkjet printing, [25] have been explored for this purpose. These methods still rely on the synthesis of plasmonic NPs separately before impregnation on the supporting substrate.…”

“…Silver NPs have diverse applications spanning multiple industries, including sensors, catalysis, and antibacterial agents. [1][2][3][4][5] Their versatility arises from their inherent cost-effectiveness, remarkable SERS activity, and excellent catalytic and antibacterial properties. The traditional method for synthesizing silver NPs is the wet chemical synthesis in solution, which provides a reliable means of controlling NPs size and distribution.…”

Facile Fabrication of Hollow Ag-Au Alloy Nanostructures Directly on Filter Paper and their Enhanced Catalytic and Antibacterial Applications

“…NPs on lter paper offer additional advantages, including catalyst recovery and reusability, wound dressing applications, and swab-based trace detection using SERS. [29][30][31] So far numerous techniques have been employed to directly grow NPs on lter paper which include drop casting, 32 chemical reduction approach, 33 successive ionic layer absorption and reaction 34 , immersion deposition, 35 thermal deposition, 36 and inkjet printing. 37 However, all these methodologies are primarily focused on the growth of solid NPs on the lter paper.…”
