Antibacterial activity of silver nanoparticles obtained by pulsed laser ablation in pure water and in chloride solution
Beilstein J. Nanotechnol. 2016, 7, 465–473, doi:10.3762/bjnano.7.40
- ][29][30][39]. Only a few studies on the antibacterial properties of PLAL-produced AgNPs are available. Among these, the only data (to the best of our knowledge) on bacterial growth inhibition by the broth dilution method are reported by Pandey et al. [31], who found MIC values of 2 µg/mL against E
Sonochemical co-deposition of antibacterial nanoparticles and dyes on textiles
Beilstein J. Nanotechnol. 2016, 7, 1–8, doi:10.3762/bjnano.7.1
- antibacterial properties. The color fastness was evaluated by immersing the coated/dyed cotton in water and monitoring the absorbance of the colored fabric. Two major issues were solved in this research: i) the antibacterial activity of the metal oxide (MO) NPs was maintained while deposited simultaneously with
- the sonochemical vs conventional dip (exhaustion) dyeing. Morphology of the coating The sonochemical technique appears as an efficient method for coating of substrates and textiles in particular [6][10]. This is reflected in the retention of the antibacterial properties of the coated fabrics even
- of the NMR measurement. Antibacterial activity The antibacterial properties of sonochemically produced MO NPs synthesized from ethanol/water solution were previously evaluated and reported [6][10]. In the current paper, the antibacterial properties of entirely water-based synthesized MO NPs complexed
Ultrastructural changes in methicillin-resistant Staphylococcus aureus induced by positively charged silver nanoparticles
Beilstein J. Nanotechnol. 2015, 6, 2396–2405, doi:10.3762/bjnano.6.246
- Abstract Silver nanoparticles offer a possible means of fighting antibacterial resistance. Most of their antibacterial properties are attributed to their silver ions. In the present work, we study the actions of positively charged silver nanoparticles against both methicillin-sensitive Staphylococcus
- , leading to structural strain in and permeability of the bacterial cell wall. This finding provides a major mechanism to explain the antibacterial properties of silver nanoparticles on Staphylococcus aureus. Results and Discussion Characterization of AgNPs TEM images of silver nanoparticles (Figure 1a
Novel ZnO:Ag nanocomposites induce significant oxidative stress in human fibroblast malignant melanoma (Ht144) cells
Beilstein J. Nanotechnol. 2015, 6, 570–582, doi:10.3762/bjnano.6.59
- antibacterial properties [12][13], are used in the cosmetics industry [14][15], and are used as nanoscale biosensors [11] and as drug carriers [16][17]. These NPs are being increasingly recognized due to their differential activity against tumor cells while being non-toxic to normal cells [18][19][20][21][22
PVP-coated, negatively charged silver nanoparticles: A multi-center study of their physicochemical characteristics, cell culture and in vivo experiments
Beilstein J. Nanotechnol. 2014, 5, 1944–1965, doi:10.3762/bjnano.5.205
- production and the manufacture of nanoparticle-containing materials. However, since the antibacterial properties of silver nanoparticles and silver salts promote an increased use in personal care products, aerosolized silver nanoparticles and silver salts in spray products such as deodorants or
An ultrasonic technology for production of antibacterial nanomaterials and their coating on textiles
Beilstein J. Nanotechnol. 2014, 5, 532–536, doi:10.3762/bjnano.5.62
- electrodes. This leads to the possibility to create a spatial electrical discharge in water. Creation of such discharge leads to the depletion of the electrodes and the formation of ZnO nanoparticles, which demonstrate antibacterial properties. At the end of this reaction the suspension of ZnO nanoparticles
- significant source of infection. To ameliorate the problem one could replace reusable textiles with disposable items. But this is quite expensive. Another more promising approach is to use antibacterial textiles. In this case it is very important to ensure the preservation of the antibacterial properties
- after washing. Antimicrobial textiles can be produced by coating textiles with antibacterial nanoparticles (NPs). NPs such as zinc oxide NPs are known to have antibacterial properties due to OH• radicals, which result from defects in their crystal structure [2]. In the case of power ultrasound
Electrospinning preparation and electrical and biological properties of ferrocene/poly(vinylpyrrolidone) composite nanofibers
Beilstein J. Nanotechnol. 2013, 4, 189–197, doi:10.3762/bjnano.4.19
- sample containing 45 wt % Fc was selected as the final product for testing the electrochemical and antibacterial properties. The Fc has antibacterial activity. But Fc molecules remain insoluble in aqueous medium and cannot diffuse through the medium, which limits the application of Fc as a bacteriostatic
Paper modified with ZnO nanorods – antimicrobial studies

- ) nanoparticles embedded into a paper matrix have been reported as exhibiting antibacterial properties [4]. Wallpaper prepared by using zinc oxide nanoparticle (~20 nm) coatings has been reported to render antibacterial surfaces that inhibit growth of bacteria such as Escherichia coli (E. coli) [5].
