Özet:
Green synthesis has become quite widespread in recent years due to its sustainability, cost-effectiveness, and environmental friendliness compared to traditional physical and chemical production methods. Previous studies have focused on the antibacterial and antitoxic properties of nanoparticles produced from plant extracts, but their integration into biological and electrochemical applications through controlled material manufacturing has never been investigated. For this reason, this thesis study aimed to produce controlled nanoparticles and materials for specific applications using two sustainable methods like green synthesis and additive manufacturing. First, silver, gold, titanium dioxide, zinc oxide, and iron oxide nanoparticles were produced from waste broccoli extracts using the green synthesis method. Secondly, the hyperthermia application of kirigami meta-structured hydrogels additively manufactured from N-isopropylacrylamide, polyethylene glycol, gold nanoflowers, polydopamine, and rose bengal photo-initiators using a micro-stereolithography process for photothermal therapy. The developed structures were demonstrated, and the physicochemical, thermal, morphological, and biological behaviors of hydrogels were examined. Lastly, a sustainable, flexible, quasi-solid-state micro-supercapacitor was developed using a direct ink-writing process. The conductive ink was made from zinc oxide nanoparticles and calcined broccoli waste, with polyvinyl alcohol/potassium hydroxide serving as the electrolyte. In this thesis, it has been shown that nanoparticles produced by green synthesis using two different additive manufacturing processes can provide environmentally friendly and sustainable results not only for biological but also thermal and electrical applications, compared to traditional methods.
