Grafting Co and Ni tetra(amino)phthalocyanines on mesoporous silica nanoparticles

Orhan Şişman, Fatih Kurtuldu, Anna Prnová, Nikolas Király et autres

Microemulsion-assisted sol–gel derived mesoporous silica nanoparticles (MNP) were functionalized with carboxyl (–COOH) ligands using (3-Triethoxysilyl) propyl succinic anhydride (TESPSA) to enable the grafting of cobalt and nickel tetra(amino)phthalocyanines (CoPc-A and NiPc-A). Electron microscopies (SEM and TEM) revealed uniform spherical nanoparticles with diameters …

Photodynamically Active Zinc‐Phthalocyanine Loaded Mesoporous Bioactive Glass Nanoparticles for Biomedical Applications

Fatih Kurtuldu, Orhan Şişman, Gustavo Galleani, Milan Masař et autres

Photodynamic therapy (PDT) is a promising approach for treating infections and cancer. However, the clinical translation of many photosensitizers is hindered by poor water solubility and tendency to aggregate. To overcome these limitations, zinc phthalocyanine (ZnPc), a highly effective photosensitizer, is loaded …
