This paper presents the improvement of the antimicrobial character of woven fabrics based on cotton. The woven fabrics were cleaned in oxygen plasma and treated by padding with silver chloride and titanium dioxide particles. The existence of silver and titanium on woven fabrics was evidenced by electronic microscope images (SEM, EDAX) and by flame atomic absorption spectrophotometry. The antimi...

BACKGROUND Topical antimicrobials are employed for prophylaxis and treatment of burn wound infections despite no established susceptibility breakpoints, which are becoming vital in an era of multidrug-resistant (MDR) bacteria. We compared two methods of determining topical antimicrobial susceptibilities. METHODS Isolates of Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (...

Zincand silver-doped mullite ceramic discs were prepared and tested as potentially resistant materials against bacterial adhesion and biofilm formation. Elemental analysis and X-ray diffraction studies showed that zinc ions were incorporated in the structural framework of the mullite, while silver ions remained outside the mullite crystal lattice, which allowed their slow (0.02 ppm/24 hours) le...

The direct write technology provides an interesting opportunity for plugging blind via holes as a more precise alternative to currently used screen printing processes. This technology provides a complete, void-less filling of the via and fabrication of the interconnects extending from the via in one single step. After deposition, the material is heat treated (sintered) to densify into a highly ...

Bacterial resistance to Ag(I) has been reported periodically with isolates from many environments where toxic levels of silver might be expected to occur, but initial reports were limited to the occurrence of resistant bacteria. The availability of silver-resistance conferring DNA sequences now allow genetic and mechanistic studies that had basically been missing. The genes determining Ag(I) re...

The major challenge the world is facing today is the mode of treatment of pathogenic bacteria which have become resistant to the existing antibiotics. Day by day, the resistance to existing antibiotics or drugs is increasing for one or other reasons. This increasing incidence of antibiotic resistance among the microbial organisms necessitates an alternate therapy to curb the resistant infectiou...

Resistance to silver compounds as determined by bacterial plasmids and genes has been defined by molecular genetics. Silver resistance conferred by the Salmonella plasmid pMGH100 involves nine genes in three transcription units. A sensor/responder (SilRS) two-component transcriptional regulatory system governs synthesis of a periplasmic Ag(I)-binding protein (SilE) and two efflux pumps (a P-typ...

The misuse of antibiotics combined with a lack newly developed ones is the main contributors to current antibiotic resistance crisis. There dire need for new and alternative antibacterial options nanotechnology could be solution. Metal-based nanoparticles, particularly silver nanoparticles (NAg), have garnered widespread popularity due their unique physicochemical properties broad-spectrum acti...
