Silver colloidal nanoparticles : effect on matrix composition and structure of ...
Monteiro, D. R.; Silva, Sónia Carina; Negri, M.; Gorup, L. F.; Camargo, E. R.; Oliveira, Rosário; Barbosa, D. B.; Henriques, MarianaAim : The aim of this study was to assess the effect of different silver nanoparticles (SN) concentrations on the matrix composition and structure of Candida albicans and Candida glabrata biofilms. Methods and Results : Candida biofilms were developed in 6-well microtiter plates during 48 h. After, these biofilms were exposed to 13·5 or 54 μg SN ml−1 for 24 h. Then, extracellular matrices were extracted from bi...
Silver nanoparticles : influence of stabilizing agent and diameter on antifunga...
Monteiro, D. R.; Silva, Sónia Carina; Negri, M.; Gorup, L. F.; Camargo, E. R.; Oliveira, Rosário; Barbosa, D. B.; Henriques, MarianaAim : The purpose of this work was to evaluate the size-dependent antifungal activity of different silver nanoparticles (SN) colloidal suspensions against Candida albicans and Candida glabrata mature biofilms. Methods and Results: The research presented herein used SN of three different average sizes (5, 10 and 60 nm), which were synthesized by the reduction of silver nitrate through sodium citrate and which w...

Monteiro, D. R.; Silva, Sónia Carina; Negri, M.; Camargo, E. R.; Oliveira, Rosário; Henriques, Mariana; Barbosa, D. B.Objectives: Fungal infections in immunocompromised patients have been contributing to the increasing morbidity and mortality of these patients, especially associated to yeast resistance to antifungal therapy. The increase in antibiotic-resistant microorganisms has prompted interest in the use of silver as an antimicrobial agent. Thus, the aim of this study was to evaluate the antifungal efficacy of silver nanop...
