Abstract
Magnesium phthalocyanine nanoparticles (MgPc) were developed in aqueous phase and the effect of anionic, cationic and non-ionic surfactant on the preparation of nanoparticles was evaluated. The sonication time, concentration of dye and the dispersing agents showed significant effects on the shape and size of the nanoparticles. The absorption spectra of nano MgPc dyes were investigated to confirm the formation of nanoparticles. The current study is expected to open a new gateway toward various applications for water insoluble dyes, especially towards biological activity of the nanomaterials.
