Antifungal activity of TiO2-CeO2 nanofibers against Candida fungi

Elucidating the effect of TiO2 nanoparticles on mung bean rhizobia via in vitro assay: Influence on growth, morphology, and plant growth promoting traits

“…Li et al [73] have also attributed the antimicrobial nature of TiO 2 NPs to generation of ROS such as superoxide and hydroxide ions. The antifungal activity of TiO 2 –CeO 2 nanofibres against Candida albicans, Candida glabrata , and Candida krusei has been attributed to oxidative stress and impairment of the fungal enzymatic activities [74]. Haffner et al [67] synthesized phospholipid bilayers and studied the interaction and photo‐oxidative membrane destabilization by TiO 2 NPs.…”

Effects of Processing Variables on the Morphology and Microstructural Characteristics of TiO2 Fibers Produced by Solution Blow Spinning

“…It was adapted between 2012 and 2015 for the production of micrometer and submicrometer nanofibers from ceramic materials [8][9][10] . In this sense, in recent years, several studies have demonstrated the efficiency of the SBS technique in the production of nanofibers and submicrometric ceramic fibers, such as ferrites [11][12][13] , SiO 2 14-16 , CeO 2 17 and TiO 2 [18][19][20][21] . These studies also demonstrated that SBS is very influenced by processing variables, because the efficacy of the injection of the solution through the coaxial nozzle, the stretching of the polymeric solution by the high-pressure gas stream and the solvent evaporation is intimately dependent of type and amount precursor material, feed rate and air pressure.…”

Influence of TiO2 Nanoparticles on the Resistance of Cementitious Composite Materials to the Action of Fungal Species

“…On one hand, there are reports showing the difficulty of homogeneous dispersion of nano-TiO 2 in the cementitious matrix for cases where the amount of nanoparticles introduced is greater, they tend to agglomerate locally and the cementitious composite becomes inhomogeneous in terms of selfcleaning capacity [17,35,59]. On the other hand, by carrying out a parallel with studies on biocidal evolution in general, which indicate that in the case of too high a concentration of biocidal substance, the cell is no longer affected, and it is necessary in most cases to identify the optimal concentration of biocidal substance to obtain a biocidal effect [31,84,85], there is also in the case of these cementitious composites the possibility of too much activity, to which the cells no longer react. By correlating with some references reported in the literature, we can advance the hypothesis that fungi have the ability to bind TiO 2 particles and fix them in the mycelium.…”

“…By correlating with some references reported in the literature, we can advance the hypothesis that fungi have the ability to bind TiO 2 particles and fix them in the mycelium. Under conditions of too high concentration of nano-particles, the reaction of the fungi will be of concentration-induced resistance and the performance is no longer achieved [84,85].…”
