“…The bactericidal effect of the electric field was also not considered, even though the bacterial fluid was not allowed to completely dry off before microplasma treatment and the distance between the electrode and samples was maintained at 2 mm. In this situation, the main functional species of atmospheric pressure plasma sterilization were the chemical substances produced by the plasma [ 20 , 21 , 22 , 23 , 24 ]. After 48 h of incubation, the mannitol salt agar changed color from red to yellow; this was because of sugar fermentation caused by S. aureus .…”

“…Multiple research results [ 20 , 21 , 22 , 23 , 24 ] have revealed that the reactive species generated by the plasma play the most important role in the plasma sterilization process. Multiple kinds of active species are considered to enhance the antimicrobial effects of plasma in general; they include various types of electrons, ions, radicals, UV light, electric fields, and metastable [ 25 ].…”

The direct and indirect bactericidal effects of dielectric barrier discharge (DBD) cold atmospheric-pressure microplasma in an air and plasma jet generated in an argon-oxygen gas mixture was investigated on Staphylococcus aureus and Cutibacterium acnes. An AC power supply was used to generate plasma at relatively low discharge voltages (0.9–2.4 kV) and frequency (27–30 kHz). Cultured bacteria were cultivated at a serial dilution of 10−5, then exposed to direct microplasma treatment and indirect treatment through plasma-activated water (PAW). The obtained results revealed that these methods of bacterial inactivation showed a 2 and 1 log reduction in the number of survived CFU/mL with direct treatment being the most effective means of treatment at just 3 min using air. UV–Vis spectroscopy confirmed that an increase in treatment time at 1.2% O2, 98.8% Ar caused a decrease in O2 concentration in the water as well as a decrease in absorbance of the peaks at 210 nm, which are attributed NO2− and NO3− concentration in the water, termed denitratification and denitritification in the treated water, respectively.

“…Nano-sized silver [60], zinc oxide and titanium dioxide are used for utilizing anti-bacterial characteristics. Metallic ions [61,62] and metallic compounds show specific sterilizing reaction [63]. Antimicrobial finish is vital so that (1) to defend the fabric consumer opposed to pathogenic systems, (2) to safeguard wearer opposed to micro-organisms that causes odor, (3) to endure the laundry procedure, (4) to defend the fabrics from destruction affected by rot, mold, mildew generating micro-organisms (5) to defend the fabrics from decline, staining, (6) to help keep a harmless hygienic setting, and (7) anti-microbial completions and cures in fabrics may assist to regulate septic situation, and by halting microbial evolution may increase the lifespan of the merchandise [64].…”

Nano technology refers to enhancing the function and delivering the upcoming smart solutions to products at the nanoscale level. It relates to organizing the molecules for altering in dimension and characteristic for improvement like smart fabric. These fabrics could assist producers with the added prominence on a standard of living, visual attraction, and system wanted technological produces. Nanosize particles can unveil unpredicted characteristics dissimilar from the bulk matter. The fundamental principle is that the features could radically be altered after the material is decreased to the nanometer scale. Nanotechnology has multipurpose functions in fabric manufacturing in producing the stain and wrinkles defiance, flame retardant, antimicrobial and antistatic properties, moisture control, ultraviolet protection, and release features. The nanomaterials inside the fabric could influence numerous qualities, comprising reduction, electrical conductivity, flammability, and strength. Nanotechnology has additionally created a significant impression on various application and implementation. Nano-doctored fabrics may advance numerous fabrications as the nano-science progresses further.

Nano Technology means optimizing performance and providing smart solutions for the future. It means configuring molecules to change in size and properties for enhancement as in the case of smart fabrics. Smart fabrics can help manufacturers and designers with the increased emphasis on lifestyle, aesthetic appeal and form demanded for technological products. Nanosize particles can exhibit unexpected properties different from those of the bulk material. The basic premise is that properties can dramatically change when a substance's size is reduced to the nanometer range. Nanotechnology has versatile applications in Textile Chemicals industry in manufacturing garments with stain resistance, flame retardant finishes, wrinkle resistance finishes, moisture management, antimicrobial qualities, UV protection, and soil release properties. Incorporating nanomaterials into a textile can affect a host of properties, including shrinkage, strength, electrical conductivity and flammability. Nanotechnology has also made a tremendous impact on functionality and performance. Nano-treated textiles may lead to many inventions as the science develops in future.
