In this study, for the first time, we described organic–inorganic hybrid nanoflowers using crude egg white as the organic component and copper (II) ions as the inorganic component under the mild conditions. The synthesized ...
ELISA Sisteminde Protein-İnorganik Hibrit Konjugatın Kullanılabilirliği

Ekremoğlu, Murat; Altinkaynak, Cevahir (Eskişehir Teknik Üniversitesi, 2020)

In the Enzyme-linked immunosorbent assay method (ELISA), it is important to increase the immobilization efficiency of the functional molecules on the microplate and increase the signal-to-noise ratio in order to detect the ...
Evaluating the activity and stability of sonochemically produced hemoglobin-copper hybrid nanoflowers against some metallic ions, organic solvents, and inhibitors

Altinkaynak, Cevahir (Elsevier, 2021-06-30)

The disadvantage of the conventional protein-inorganic hybrid nanoflower production method is the long incubation period of the synthesis method. This period is not suitable for practical industrial use. Herein, protein-inorganic ...
Evaluation of organic-inorganic hybrid nanoflower's enzymatic activity in the presence of different metal ions and organic solvents

Altinkaynak, Cevahir; Gulmez, Canan; Atakisi, Onur; Özdemir, Nalan (Elsevier, 2020)

In the present study, lipase-inorganic hybrid nanoflowers (L-hNFs) have indicated to possess several novel char- acteristics that are significant in terms of industrial worth. In detail, we reported the production of lipase- ...
Fabrication of myoglobin hybrid nanoflowers for decolorization process of evans blue and congo red

Türk, Merve; Altinkaynak, Cevahir; Yangin, Nazlican; Özdemir, Nalan (Elsevier, 2022-08-20)

Here, myoglobin hybrid nanoflowers (MbNFs@Cu) were synthesized in various pH values and protein concen- trations considering the organic–inorganic hybrid nanoflower method for the first time. Synthesized material was ...
Fluorescent Copper Phosphate Nanoflowers: A Novel Toxicity Investigation Study Based On Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae) Larvae

Eskin, Ata; Altinkaynak, Cevahir; Türk, Merve; Özdemir, Nalan (Bitlis Eren Üniversitesi, 2020)

Organic-inorganic hybrid nanoflowers with commercialization potential are the novel materials and are widely used in many experimental applications, recently. However their potential toxicity values of these nanoflowers ...
Hemoglobin-metal2+ phosphate nanoflowers with enhanced peroxidase-like activities and their performance in visual detection of hydrogen peroxide

Altinkaynak, Cevahir (The Royal Society of Chemistry, 2021)

Hemoglobin (Hgb)–metal 2+ 2+ 2+ phosphate nanoflowers (Hgb–X -Nfs) were synthesized using Co 2+ , Zn , 2+ 2+ Ca , and Fe separately as inorganic components, to generate a visual hydrogen peroxide (H2O2) biosensor for ...
