“…The antibacterial activity of the generated AgNPs against both pathogenic bacteria was assessed by looking at the bacterial growth kinetics in the Letheen Broth medium. The results revealed that the bacterial elimination was around 95.24% for S. aureus and 93.6% for E. coli , showing that the commercial standard of GB/T 20944.3‐2008 for antibacterial performances may be met by the AgNPs as they have been synthesized 86 . Additionally, the antibacterial activity of newly synthesized AgNPs was shown to be comparable to that of AgNPs observed in other plant extracts and naturally occurring carbohydrate polymers (Table 1).…”

The various applications of silver nanoparticles (AgNPs) are brutally hampered in the practical field due to their instability and aggregation features. Thus, highly stable colloidal AgNPs were produced in obedience to the principle of 'green chemistry' that uses natural dyes extracted from gardenia fruits as stabilizing and simultaneously as reducing agents. The effect of operating conditions on the synthesis of AgNPs was studied using a one-variable-at-a-time technique to maximize the growth of particles.The analysis of AgNPs produced at optimum reaction parameters discovered that the particles are face-centered cubic metallic silver, mostly in spherical shapes, nanoranged in diameter (23.4 ± 6.4 nm) with a confined size distribution, enormously crystalline surface (d-spacing = 0.233 nm), firmly stabilized (zeta potential = À29.0 mV) by a thin membrane of gardenia phytochemicals. They exhibited significant bacterial reduction inhibition against the growth of Escherichia coli and Staphylococcus aureus owing to the strong antibacterial function of nanosilver.

“…As a natural fabric, cotton fabric has been popular with people because of its superior comfort, breathability, and hygroscopicity compared with synthetic fabrics, and is frequently used as underwear (Li et al 2020). However, the porous structure of the cotton fabric can support bacterial growth, which harms human health (Zhou et al 2021). In recent years, N-halamines stand out from many traditional antibacterial agents through their advantages of rapid inactivation, broad-spectrum antibacterial, longterm stability, renewable antibacterial properties, and safety for humans and the environment, and it has received more and more attention from researchers (Dong et al 2017).…”

In this study, functional coatings with N-halamine structure were formed on cotton fabrics by dopamine (DA) auto-deposition and DA/Polyethyleneimine (PEI) covalent co-deposition, respectively. SEM UV-Vis and XPS had con rmed the deposition of DA and DA/ polydopamine (PDA) on the cotton fabrics. When the mass ratio of DA/PEI was 1:1.5, a uniform functional coating was formed. XRD had indicated that the coating and the oxidative sodium hypochlorite solution did not affect the crystal structure of cellulose. The DA/PEI co-deposited modi ed cotton fabric had excellent antibacterial property after chlorination, and the inactivation rate against E coli and S aureus could reach 100% with a contact time of 30 min. The functional coating on the cotton fabric remained stable after 50 washing cycles. The UPF values and the wrinkle recovery angle (WRA) tests showed that the DA/PEI co-deposited coating imparted great durable press and UV protective properties to the cotton fabric. The breaking strength loss rate of the modi ed cotton fabrics after chlorination was about 20%, which had little effect on the wearing property.
