The effect of some process parameters on colloid and photophysical characteristics of nanoparticles.
Notes: (A) Hydrodynamic diameter and PDI of PVM/MA nanoparticles produced by solvent displacement in function of the initial PVM/MA concentration. (B) Efficiency of the AlPc association to PVM/MA nanoparticles in the function of the AlPc concentration in precipitation medium; (C) influence of Tween 20 and AlPc concentrations on the ΦF (excitation λ 350 nm, emission λ 690 nm) of AlPc nanoparticles dispersed in phosphate buffered saline, pH 7.2, at a concentration equivalent to 1 μM AlPc.
Abbreviations: PVM/MA, poly(methyl vinyl ether-co-maleic anhydride; AlPc, aluminum–phthalocyanine chloride; ΦF, fluorescence quantum yield; PDI, polydisperity index.
