Comparison study of synthesized red (or Blood) orange peels and juice extract-nanoflowers and their antimicrobial properties on Fish Pathogen (Yersinia ruckeri)
Demirbaş, Ayşe (Springer, 2021)In this work, we synthesized blood orange peel extract-copper (II) (Cu2+) ions nanoflower (NFs) and blood orange juice extract-copper (II) (Cu2+) ions nanoflower examine their antimicrobial properties on the fish pathogen ... -
Facile synthesis of hybrid nanoflowers using glycine and phenylalanine and investigation of their catalytic activity
Demirbaş, Ayşe; Karslı, Barış; Öcsoy, İsmail (Wiley, 2023)In the context of the proposed work, two different amino acids (Glycine, Phenylalanine) have interacted with copper ions in a phosphate buffer (PBS) in place of enzymes. This interaction resulted in the nucleation of copper ... -
