Phthalocyanines are synthetic dyes which are shown to be good photoconverters which can be applied in a photoelectrochemical cell constructed of semiconducting and metallic electrodes. By means of spectroscopic investigation (absorption,fluorescence

In this review we present an updated survey of the main synthesis methods of gold nanoparticles (AuNPs) in order to obtain various tailored nanosystems for biomedical imaging. The synthesis approach significantly impacts on the AuNPs properties such

Several studies have shown that some anti-oxidant natural compounds in combination with photodynamic therapy (PDT) can enhance the effectiveness of treatment. The aim of this study is to evaluate the effect of silymarin (SIL) in combination with 5,10

The aim of our study was to assess the effect of the combined treatment of Metformin (Metf) and 5, 10, 15, 20-tetra-sulfophenyl-porphyrin (TSPP)–mediated photodynamic therapy (PDT) on an in vivo tumour model. Wistar male rats were divided in 6 grou

The purpose of this paper is to follow the influence of chlorine or fluorine substituents of phthalocyanine dyes on their spectroscopic, photothermal and photoelectric properties. Such influence is discussed in term of the resonance effects occurring

The kinetics of photocurrent generated in the photoelectrochemical cell (PEC) with phthalocyanine (Pc) dyes in the microsecond time scale was discussed. The shape of the kinetics is rather complex and it was discussed in terms of molecular phenomena

In this paper, we report the spectroscopic properties of two newly synthesized phthalocyanines when substituted with short and long alkyl chains dissolved in dimethyl sulfoxide. The dyes are non-fluorescent and show a weak tendency for dimer formatio
