Ateş, Burhan; Ulu, Ahmet; Asiltürk, Meltem; Noma, Samir Abbas Ali; Demirel Topel, Seda; Dik, Gamze; Özhan, Onural; Bakar, Büşra; Yıldız, Azibe; Vardı, Nigar; Parlakpınar, Hakan (Elsevier, 2024)If the appropriate immobilization method and carrier support are not selected, partial decreases in the activity of enzymes may occur after immobilization. Herein, to overcome this challenge, an excitation mechanism that ... -
Near-infrared inducible supports in bio-catalysts design: A useful and versatile tool in enhancement of enzyme activity
Noma, Samir Abbas Ali; Dik, Gamze; Gürses, Canpolat; Kuruçay, Ali; Demirel Topel, Seda; Ulu, Ahmet; Asiltürk, Meltem; Ateş, Burhan (2024)Immobilized enzymes have encountered two main challenges: Reduced enzyme activity compared to free enzymes and exhausted immobilized enzymes due to reusability. Herein, we suggested a promising activity enhancement strategy ... -
Synthesis and characterization of Near-Infrared (NIR)-light triggerable upconverting nanoparticles to enhance activity of immobilized l-asparaginase
Dik, Gamze; Noma, Samir Abbas Ali; Ulu, Ahmet; Demirel Topel, Seda; Asiltürk Ersoy, Meltem; Ateş, Burhan (4. EURASIA Biochemical Approaches & Technologies-4.EBAT Conference, 2022)In this study, PEG-L-ASNase enzyme was immobilized on UCNPs and its activity was improved by NIR. NaYF4: Yb3+, Er3+/PEI UCNPs were characterized to observe structural and morphological changes before/after enzyme immobilization. ...
