“…These results suggest that N-halamine modi cation do not signi cantly possess cell toxicity; the results are in agreement with other reported results for similar studies. (Demir, Cerkez et al 2015;Demir, Broughton et al 2017;Grabchev, Staneva et al 2019;Gao, Su et al 2020) However, it is also assumed that the small toxicity observed in the present experiment may due to release or dissociation of Cl + into cell medium with time from N-halamine modi ed chitosan@AgNPs-NWFC. The release can be controlled by optimizing the chlorine contents at nonwoven cotton fabric and with repeated washing with water without affecting fabricated fabric properties.…”

Nonwoven cotton fabric has been fabricated and designed for antibacterial applications using low cost and ecofriendly precursors. The treatment of fabric with alkali leads to formation of active sites. The surfaces were dip coated with silver nanaoparticles and chitosan. The surface was chlorinated in next step to transform amide (N-H) groups in chitosan into N-halamine (N-Cl). The modified and unmodified surfaces of the nonwoven cotton fabric have been characterized by FTIR, SEM, and XRD. The active chlorine loading is measured with iodine/ sodium thiosulphate. The antimicrobial activity and cell toxicity assay were carried out with and without modifications of nonwoven cotton fabric. The antimicrobial efficacies of loaded fabric were evaluated against four bacterial species (Micrococcus lutes, Staphylococcus aurea, Enterobacter aerogenes, and E.coli). It was found that modified fabric exhibited superior efficiency against gram-positive and gram-negative bacterial strains as compared to their bulk counterparts upon exposure without destroying and affecting fabric nature. The overall process is economical for commercial purposes. The modified fabric can be used for antimicrobial, health, and food packaging industries, and in other biomedical applications.

“…The microbiological activity of D3 is comparable with the activity against the same strains using other PAMAM and PPI dendrimers modified with 1,8-naphthalimides. [17][18][19][20][21] The antimicrobial effect of cotton fabric treated with D3 was tested against the model strains B. cereus, P. aeruginosa and C. lipolytica. We found that cotton fabric treated with D3 effectively reduced the growth of B. cereus and C. lipolytica by about 80% and 50%, respectively, and about a 20% growth reduction in P. aeruginosa was observed ( Figure 6).…”

“…[12][13][14][15] Because the monomeric 1,8-naphthalimide compounds also exhibit biological activity, we have studied the antimicrobial and anticancer activity of PAMAM and PPI dendrimers and their metal complexes modified with 1,8-naphthalimides. [16][17][18][19][20][21] The deposition of such bioactive dendrimers on the surface of textile materials creates textiles with high antimicrobial activity and results in better control of biofilm formation. [22,23] Such textile materials may find application as wound dressings, hospital textiles, linen, towels, filters, and in other medical devices.…”

A three‐step synthesis was implemented to prepare a quaternary ammonium functionalized blue fluorescent poly(propylene imine) dendrimer modified with pyridinium salt of 4‐acylamino‐1,8‐naphthalimide. The new cationic dendrimer absorbs in the ultraviolet light region and emits blue fluorescence. Its spectral characteristics in organic solvents and in an aqueous solution were studied. The influence of pH on the fluorescence intensity of the dendrimer was established with regard to its use as a pH sensor. The effect of hydroxyl ions on the absorption and fluorescence spectra in dry N,N‐dimethylformamide was also investigated. The antimicrobial activity of the dendrimer was assessed against model pathogenic microorganisms in agar, liquid medium, and after its deposition on cotton fabric.

C ANCER is a serious concern right away which severely affects the mankind. Recently, the centre of interest of pharmaceutical industry is to develop newer drug molecules with very less or no toxicity to prevent and cure this life-threatening disease. Nature is the origin of remedies for human. Natural therapeutic agents brought a great change in recent drug market, as these are simple, safer, eco-friendly, low-cost, and less toxic in respect to commonly using drugs. Natural anticancer agents are selective in their functions and targetfully act on tumor cells without having any effect on normal cells. Cancer is a complex phenomenon which requires many signaling pathways. Natural therapeutic agents are the appropriate candidates to develop anticancer drug on account of their pleiotropic actions on target events with diverse manners. In this review we have collected a basket, flooded with latest information (2010-2020) on prevention and treatment of cancer with several products from nature, such as phytohemical (artemisinin, parthenolide, thapsigargin, curcumin, resveratrol, quercetin, coumarin, calcitriol, capsaicin, fisetin, evodiamine, boswellic acid, betulinic acid, deoxyelephantopin), plant (Rosmarinus officinalis L., Aloe vera, Olea europaea), functional foods (pomegranate, mango, amla, garlic, ginger, broccoli, mushroom, green tea, coffee, honey), textile and marine product based on their mechanism of action.
