“…In the past, a large number of antibacterial fabrics have been produced using silver, copper, and gold nanoparticles. − However, even though these nanoparticles have good antibacterial potential, they are either very expensive, unstable in the environment, or cytotoxic. − On the other hand, textile fabrics functionalized with titanium dioxide nanoparticles (TiO 2 NPs) eliminate these barriers and demonstrate nontoxic, biocompatible, inexpensive, and highly stable textile finishes. ,, Besides their photoinduced antibacterial nature, TiO 2 NPs also display photocatalytic degradation activity against several chemical compounds such as organic dyes (methylene blue, congo red, etc. ) and odorous gases (ammonia, mustard, etc.…”

Ordinary textiles are very often malodorous and the origin of cross-infection. Their microclimate, consisting of moisture, contaminants, and sweat, provides favorable conditions for microbial growth. Therefore, simple approaches of surface modification using functional materials are widely adopted to introduce antibacterial properties. This study reports a simple and low cost technique that renders cotton fabrics antibacterial. Manganese (Mn)-doped photocatalytic titanium dioxide (TiO2) nanoparticles of ∼150 nm average diameter have been prepared by sol gel and applied on textile fabrics using a silicone binder. The treated fabrics displayed 100% reduction of Staphylococcus aureus (Gram-positive) and Klebsiella pneumoniae (Gram-negative) populations within 120 min under sunlight, demonstrating first order of reduction kinetics. Moreover, the functionalized fabrics demonstrated complete degradation of a methylene blue (MB) dye adsorbed on their surface, under both UV and visible light irradiation, turning them white. A similar effect was observed when the treated fabrics were immersed in a MB dye solution and subsequently irradiated. Here, the cotton fabrics functionalized with Mn-doped TiO2 nanoparticles were able to discolour the dissolved MB dye, demonstrating a water purification effect. In addition, the modified fabrics were resistant to several laundry cycles. Physical properties like mechanical strength, color, breathability, and aesthetic of the treated cotton fabrics remained unchanged. The modified cotton fabrics can be envisioned as antibacterial, antiodorous, and self-cleaning textiles for sports, medical uses, uniforms, fashion, home furnishing, and leisure activities. Finally, the treated textiles were found to be biocompatible.

“…In these experiments, no chemical or physical carriers were used to bind particles to the mask surface; however, several methods are available for coating different matrices, including textiles or other materials used for face masks and PPE (Table 2) [71][72][73][74][75][76][77][78][79][80]. For example, among the different available techniques, the combination of natural polymers, such as chitosan (CS) with inorganic materials, such as titanium dioxide (TiO 2 ), to obtain hybrid composites (CS-TiO 2 ), seems promising for both increased stability and enhanced antimicrobial properties [81,82].…”

The COVID-19 pandemic has led to countries enforcing the use of facial masks to prevent contagion. However, acquisition, reuse, and disposal of personal protective equipment (PPE) has generated problems, in regard to the safety of individuals and environmental sustainability. Effective strategies to reprocess and disinfect PPE are needed to improve the efficacy and durability of this equipment and to reduce waste load. Thus, the addition of photocatalytic materials to these materials, combined with light exposure at specific wavelengths, may represent promising solutions. To this aim, we prepared a series of masks by depositing micrometer-sized TiO2 on the external surfaces; the masks were then contaminated with droplets of bacteria suspensions and the coatings were activated by light radiation at different wavelengths. A significant reduction in the microbial load (over 90%, p < 0.01) was observed using both Gram negative (E. coli) and Gram positive (S. aureus) bacteria within 15 min of irradiation, with UV or visible light, including sunlight or artificial sources. Our results support the need for further investigations on self-disinfecting masks and other disposable PPE, which could positively impact i) the safety of operators/workers, and ii) environmental sustainability in different occupational or recreational settings.

H ERE in focus on the nano technology and biotechnology as new technique knock for textile multifunctional finishing process with highly effective and recent research concentrate and restrict on using this promising technology concomitant also advanced highly effective tools namely sonication, plasma, microwave for finding out how to reduce conventional techniques utilities. Nanotechnology is revolutionizing the way in which the functional properties are imparted to the textile materials. Cotton, the king of natural fibers, requires nanotechnological interventions to achieve the functionalities like antibacterial, UV protecting, super hydrophobic and flame retardancy. Nano-finishing also helps to impart these properties without affecting the inherent comfort nature of cotton. In addition, the amount of material required to impart the functional property is relatively less due to its nano-size range. Enzymes have become an indispensable part of textile processing and are utilized for a wide variety of applications in the modern textile industry. Various established enzyme-based processes that are currently used in the textile industry demonstrate the potential of industrial biotechnology to successfully provide 'greener' alternatives
