Evaluation of Long–Lasting Antibacterial Properties and Cytotoxic Behavior of Functionalized Silver-Nanocellulose Composite

“…The antibacterial mechanism of the Ag–ONCs nanocomposites was discussed in our previous works [ 18 , 20 ], in which the antibacterial behaviour of the Ag–ONCs was attributed to the synergic effect of different functionalities on the cellulosic surface, combined with the intrinsic properties of Ag. Ag NPs seems to be able to interact with the cell surface of different bacteria, according to a mechanism already reported in other studies [ 12 , 47 ].…”

“…Furthermore, silver nanoparticles were used in conjugation with biomolecules, such as cellulose and chitosan, to obtain organic-inorganic composite with specific antibacterial activity [ 18 , 19 , 20 ] and resistance against bacteria, fungi, protozoa, and virus contamination [ 11 , 21 , 22 , 23 ]. Nevertheless, the over-using of extra toxic reducing reagents or capping/dispersing agents during the synthesis of uniform and stable cellulose-Ag nanohybrids strongly limit their application in health sector [ 24 ] and represent a cause of environmental pollution [ 25 ].…”

Recent advances in biobased and biodegradable polymer nanocomposites, nanoparticles, and natural antioxidants for antibacterial and antioxidant food packaging applications

“…In the last few years, AgNPs have been considered one of the most used inorganic nanomaterials in nanocomposites for antimicrobial food packaging, mainly due to their effectiveness against a broad spectrum of bacteria, fungi, and yeasts, as well as their unique physicochemical properties (Adel et al., 2021; Shankar et al., 2021). The antibacterial effect of AgNPs may be mainly related to their adhesion to the bacterial wall, which interacts with cell membrane components (lipids and proteins), and subsequent penetration into cells, causing damage to DNA and proteins.…”

A Facile Green Fabrication and Characterization of Cellulose-Silver Nanoparticle Composite Sheets for an Antimicrobial Food Packaging

“…Furthermore, the in vitro research for AgNPs migration from commercial plastic food packaging and containers revealed that AgNPs can be released from plastics and the amount released was sufficient to kill microorganism (46)(47)(48). Several formats of AgNP fabrication for active packaging have been developed, including absorbent pads (14,49), wrapping film (50,51), and paper sheet (52)(53)(54) with simple techniques by directly blending or coating the AgNP colloids or powders to a packaging material (55,56). However, for food preservation with active packaging, it is difficult to use colloidal AgNPs as antimicrobial agents because of the challenges in coagulation, aggregation, and fabrication (42,57).…”
