“…The high AA values shown in Figure 7a can be attributed to the large specific surface area and to the associated fast ion release rate of the NPs that were synthesized and used here. 43 In contrast to traditional wetfinishing processes, 18,50,51 the textiles with such low Ag NP loading (in the order of 10 ppm) still have high antimicrobial efficiency (against Staphylococcus Aureus (SA) and Klebsiella Pneumoniae (KP), as shown respectively in the left and right columns in Figure 7a). Minor differences in AA against SA and KP can be explained by the dissimilar defense systems of the two species against Ag ions 46 .…”

A major challenge in nanotechnology is that of determining how to introduce green and sustainable principles when assembling individual nanoscale elements to create working devices.For instance, textile nanofinishing is restricted by the many constraints of traditional pad-drycure processes, such as the use of costly chemical procedures to produce nanoparticles (NPs), the high liquid and energy consumption, the production of harmful liquid waste, and multi-step batch operations. By integrating low-cost, scalable, and environmentally benign aerosol processes of the type proposed here into textile nanofinishing, these constraints can be circumvented while leading to a new class of fabrics. The proposed one-step textile nanofinishing process relies on the diffusional deposition of aerosol NPs onto textile fibers. As proof of this concept, we deposit Ag NPs onto a range of textiles and assess their antimicrobial properties for two strains of bacteria (i.e., Staphylococcus Aureus and Klebsiella Pneumoniae).The measurements show that the logarithmic reduction in bacterial count reaches ca. 5.5 (corresponding to a reduction efficiency of 99.96%) when the Ag loading is one order of magnitude less (10 ppm; i.e., 10 mg Ag NPs per kg of textile) than in the textiles treated by traditional wet-routes. The antimicrobial activity does not increase in proportion to the Ag content above 10 ppm as a consequence of a "saturation" effect. Such low loading for

“…Investigation of reduction of AgNPs prepared by the polyol process with microwave heating on the cotton fabric surface after washing cycles was also carried out . It was reported that the content of AgNPs on the prepared fabrics was reduced from 570 to 230 mg/g for washing cycles ranging from 5 to 15 times.…”

This article provides a comprehensive understanding of development of textiles functionalized with silver nanoparticles (AgNPs). There are three established methods to fabricate textiles functionalized with AgNPs, namely, solution‐immersion, layer‐by‐layer deposition, and sonochemical. In addition, several textile types such as cotton, wool, polyester, silk, cotton/polyester blend, polyamide, and regenerated cellulose have been used for the fabrication. The AgNP deposition mechanism on textiles is mainly due to electrostatic interaction between AgNPs and textile constituents. It was exhibited that the deposition of AgNPs on textiles can transform their textiles colors. In addition, it was demonstrated that the deposition of AgNPs on textiles is not permanent, particularly against washing treatment. Textiles modified with AgNPs have several promising applications such as antibacterial, antifungal, catalyst, electronic devices, water treatment, sun protection, air treatment, and surface‐enhanced Raman scattering, which are comprehensively discussed in this article. Future challenges in fabricating textiles functionalized with AgNPs remain on how this can be carried out to improve long‐term stabilization of AgNPs on textiles to achieve their permanent deposition by employing greener approaches.

Around 650 disease-causing pathogens can be killed by silver molecules with only 6 minu of contact time, whereas general antibiotic kills only 5 to 6 disease-causing pathogens (Han and Li 2008;Thanh and Phong 2008). Nanosilvers are applied to food packaging or containers to promote their antimicrobial properties and a large number of antibacterial food packaging products using nanosilver are readily available on the market around the world.…”

Recently, food packages produced with nanoparticles, "nano-food packaging," have become more available in the current market. However, although the use of nanomaterials is increasing in food packaging applications, concern over toxicity affects consumer perceptions and acceptance. Quite a number of commercialized forms of nano-food packaging are coated or composited product with inorganic materials, for example, nanosilver and nanoclay as representative examples. Several studies have shown the possibility of nanomaterial migration from packaging or containers to foodstuff. The debate is still ongoing among researchers about the extent of migration and whether it is negligible and safe. Government agencies and stakeholders must hurry to determine use limitations and release conclusive legislation and regulations as soon as possible since nano-food packaging may have great impacts on human health. This paper aims to review the availability of nano-food packaging in the current market, report case studies on nanomaterial migration, and present the current status of safety regulations and management of nano-food packaging in leading countries across regions. This review should enable governments and researchers to develop further nanomaterial risk assessment studies.
