Antibacterial fluoromicas: A novel delivery medium

Abstract

Antibacterial fluoromicas were prepared by ion-exchanging fluoromicas with different antibacterial agents including various quaternary ammonium compounds, AgNO3, and norfloxacin. Antibacterial activities of the ion-exchanged fluoromicas were determined against Staphylococcus aureus and Escherichia coli. Minimum inhibitory concentration (MIC) and zone of inhibition (ZOI) tests were performed to determine both antibacterial effectiveness and mode of action associated with the fluoromicas. All treated fluoromicas showed excellent antibacterial activities against both types of bacteria. The antibacterial activities of treated fluoromicas were found to be either better than or the same as those of neat antibacterial agents. The repeated antibacterial activity tests demonstrated the extended activity of these systems.

Polymer-layered silicate nanocomposites in the design of antimicrobial materials

“…However, there are very few reports in the open literatures concerning the antimicrobial activity of clays loaded with organic biocides. The available information on this so far includes the use of organoclays containing benzyl-or alkylammonium salts as antimicrobial additives to topical cosmetic formulations [11] or in delivery systems [12]; bacteria removal by clays modified with cetylpyridinium in water treatment applications [13]; and the use of cationic organic molecules, chlorhexidine acetate [14], and chitosan [15,16], which are well-known disinfectants, to intercalate into layered silicates to produce antimicrobial organoclays.…”

Antibacterial Silicone-Urea/Organoclay Nanocomposites

“…Interestingly, natural clays have been used to heal skin infections since the earliest recorded history [7]. Recently it has been reported that some natural clays are very effective against Escherichia coli, Salmonella typhimurium (or aerus) and Pseudomonas aeruginosa [8,9]. Antibacterial activities of quaternary ammonium salts are also very well documented [10][11][12][13][14][15][16].…”

Oxidative Stress Induced by Organo Sliver Clay Particles in Mice

“…Furthermore intercalated with organic and natural ingredients with antibacterial consequences including cetylpyridinium, cetyltrimethylammonium, norfloxacin tetracyclines happen to be additionally analyzed. The fluoromicas as well as organo montmorillonites exhibited superb antibacterial activities [4,5].…”
