Silica nanoparticles embedded with water insoluble phthalocyanines for the photoinactivation of microorganisms
(Elsevier Science, 2018-09)
Silica nanoparticles (SiNPs) embedded with Zn(II) 2,9,16,23-tetrakis(methoxy)phthalocyanine (SiNPZnPcOCH3), Zn(II) 2,9,16,23-tetrakis(4-pyridyloxy) phthalocyanine (SiNPZnPcOPy) and Zn(II) 2,9,16,23-tetrakis(t-butyl) ...
Optimization of cellular uptake of zinc(II) 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]phthalocyanine for maximal photoinactivation of Candida albicans
(Elsevier, 2013-09)
Cellular uptake and photodynamic action of zinc(II) 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]phthalocyanine (ZnPPc4+) was examined in Candida albicans. In vitro investigations showed that ZnPPc4+ was rapidly bound to C. ...
Genotoxic effect of photodynamic therapy mediated by curcumin on Candida albicans
(2015)
Photodynamic therapy (PDT) is a promising method for localized and specific inactivation of fungi and bacteria. A nontoxic light-sensitive compound is taken up by cells, which are then exposed selectively to light, which ...
Photodynamic Therapy for Pododermatitis in Penguins
(Wiley-Blackwell, 2014-07-01)
Pododermatitis is currently one of most frequent and important clinical complications in seabirds kept in captivity or in rehabilitation centers. In this study, five Magellanic penguins with previous pododermatitis lesions ...
Effects of divalent cations, EDTA and chitosan on the uptake and photoinactivation of Escherichia coli mediated by cationic and anionic porphyrins
(Elsevier Science, 2015-03)
The effect of divalent cations, EDTA and chitosan (CS) on the uptake and photoinactivation of Escherichia coli produced by 5,10,15,20-tetrakis(4-N,N,N-trimethylammoniumphenyl)porphyrin (TMAP4+), 5,10-di(4-methylphenyl)-1 ...
Approaches to unravel pathways of reactive oxygen species in the photoinactivation of bacteria induced by a dicationic fulleropyrrolidinium derivative
(Academic Press Inc Elsevier Science, 2016-10-15)
The photodynamic mechanism sensitized by N,N-dimethyl-2-[4-(3-N,N,N-trimethylammoniopropoxy)phenyl]fulleropyrrolidinium (DPC602+) was investigated in Staphylococcus aureus cells. Different experimental conditions were used ...
Algicidal effect of blue light on pathogenic Prototheca species
(2019-06-01)
Prototheca spp. are pathogenic algae with important zoonotic potential. Most importantly, these algae often infect dairy cattle. Since there is no effective therapy against the algae, the standard recommendation is the ...
Photodynamic inactivation of Candida albicans and Candida tropicalis with aluminum phthalocyanine chloride nanoemulsion
(2019-01-01)
The in vitro susceptibilities of Candida albicans and Candida tropicalis to Antimicrobial Photodynamic Treatment with aluminum phthalocyanine chloride in nanoemulsion (ClAlPc/NE) were investigated. PS concentration- and ...
Mechanistic aspects in the photodynamic inactivation of Candida albicans sensitized by a dimethylaminopropoxy porphyrin and its equivalent with cationic intrinsic charges
(Elsevier Science, 2020-09)
Photocytotoxic effect induced by 5,10,15,20-tetrakis[4-(3-N,N-dimethylaminopropoxy)phenyl]porphyrin (TAPP) and 5,10,15,20-tetrakis[4-(3-N,N,N-trimethylaminepropoxy)phenyl]porphyrin (TAPP+4) was examined in Candida albicans ...
