Surface modification of silica-coated gadolinium oxide nanoparticles with zinc tetracarboxyphenoxy phthalocyanine for the photodegradation of Orange G

Spectroscopic characterization and photodynamic antimicrobial chemotherapy of phthalocyanine-silver triangular nanoprism conjugates when supported on asymmetric polymer membranes

Silver triangular nanoprisms were synthesized and conjugated to zinc (ZnPc) and indium (InPc) phthalocyanines prior to embedding in asymmetric membranes. Conjugation of nanoparticles increased triplet state and singlet oxygen quantum yields of the phthalocyanines as well as enhancing photodynamic antimicrobial chemotherapy (PACT) activity against bacteria (S. aureus). The ZnPc derivative showed higher PACT activity when compared to the InPc, possibly due to degradation of the latter in aqueous media.

Synthesis and photophysical studies of asymmetric zinc phthalocyanine–magnetic nanoparticle conjugates

This work reports on the synthesis and amide bond linkage of carboxylic acid functionalized asymmetric zinc phthalocyanine (ZnPc) complexes to amino magnetic nanoparticles (AMNPs).

Augmenting the catalytic activity of CoFe2O4 by substituting rare earth cations into the spinel structure

The current research work evaluates significant enhancement in photo-Fenton activity of pristine cobalt ferrite (CoFe₂O₄) by inserting very small quantity of rare earth cations such as cerium (Ce³⁺) and lanthanum (La³⁺) into its spinel structure.
