Innovative Preparation of Cellulose-Mediated Silver Nanoparticles for Multipurpose Applications: Experiment and Molecular Docking Studies
In recent years, inorganic metal nanoparticle fabrication
by extraction
of a different part of the plant has been gaining more importance.
In this research, cellulose-mediated Ag nanoparticles (cellulose/Ag
NPs) with excellent antibacterial and antioxidant properties and photocatalytic
activity have been synthesized by the microwave-assisted hydrothermal
method. This method is a green, simple, and low-cost method that does
not use any other capping or reducing agents. X-ray diffraction (XRD),
Fourier transform infrared (FTIR), field emission scanning microscopy
(FESEM), transmission electron microscopy (TEM), energy-dispersive
X-ray (EDX), and UV–visible spectroscopic techniques were used
to investigate the structure, morphology, as well as components of
the generated cellulose/Ag NPs. In fact, XRD results confirm the formation
of the face-centered cubic phase of Ag nanoparticles, while the FTIR
spectra showed that the synergy of carbohydrates and proteins is responsible
for the formation of cellulose/Ag NPs by the green method. It was
found that the green-synthesized silver nanoparticles showed good
crystallinity and a size range of about 20–30 nm. The morphology
results showed that cellulose has a cavity-like structure and the
green-synthesized Ag NPs were dispersed throughout the cellulose polymer
matrix. In comparison to cellulose/Ag NPs and Ag nanoparticles, cellulose/Ag
NPs demonstrated excellent antibacterial activity, Proteus mirabilis (MTCC 1771) possessed a maximum
inhibition zone of 18.81.5 mm at 2.5 g/mL, and Staphylococcus
aureus (MTTC 3615) had a minimum inhibition zone of
11.30.5 mm at 0.5 g/mL. Furthermore, cellulose/Ag NPs also exhibited
a significant radical scavenging property against the DDPH free radical,
and there was a higher degradation efficiency compared to pure Ag
NPs against Rhodamine B as 97.38% removal was achieved. Notably, cellulose/Ag
NPs remarkably promoted the transfer and separation of photogenerated
electron–hole (e–/h+) pairs, thereby
offering prospective application of the photodegradation efficiency
for Rhodamine B (RhB) as well as antibacterial applications. With
the findings from this study, we could develop efficient and environmentally
friendly cellulose/Ag nanoparticles using low-cost, environmentally
friendly materials, making them suitable for industrial and technological
applications
