Green-Synthesized Nanoparticles for Biomedical Sensor Technology
(Elsevier, 2024) Baran, A.; Baran, M.F.; Ipek, P.; Eftekhari, A.; Keskin, C.; Atalar, M.N.; Alma, M.H.
Sensor technology is an integral part of the many cost-effective and efficient factors possible in modern medical devices. Biosensors have good potential as they are easy, scalable, and effective in manufacturing processes. Nanotechnology has become one of the promising technologies applied in all fields of science. Biotechnologically produced metallic nanoparticles (NP) attract attention in scientific applications and technology platforms due to their extensive applications in biomedical and physiochemical fields. In recent years, the side effects caused by the use of synthetic drugs and the medical and economic problems caused by them have made the use of plants popular again. Ecofriendly, nontoxic metal-based NPs (such as gold, silver, palladium, manganese, and zinc) smaller than 100nm in size can be synthesized with extracts obtained from plants by different methods. As the sizes and shapes of NPs change, the physical, chemical, bioactive, optical, electrical, catalytic, and toxicity properties of the particles also change. Biological synthesis, also known as green synthesis, is a practical method to obtain NPs easily and ecologically without the need for high pressure, high-temperature values, and toxic chemicals. Green synthesis of NPs is carried out using different biomaterials such as bacteria, fungi, yeast, viruses, microalgae, and plant biomass/essence. Plant-mediated biosynthesis of metallic NPs occurs through biomolecules containing organic functional groups in the plant. Nanobiosensors, analytical devices combining a biologically sensitive element with a nanostructured transducer, are widely used for the molecular detection of biomarkers associated with the diagnosis of diseases and the detection of infectious organisms. Nanobiosensors show certain advantages over laboratory and many field methods due to their inherent specificity, simplicity, and rapid response. In this study, advancements in the development of nanobiosensors are illuminated. Considering all these aspects, it can be said that nanobiosensors enable diagnostic tools with increased sensitivity, specificity, and reliability for medical applications. © 2025 Elsevier Inc.

Production of Value-Added Cosmetic Products From Cold-Pressed Helianthus Annuus L. Oil and Pulp
(Jomard Publishing, 2024) Karadag, M.; Baran, A.; Güneş, Z.
Recycling, in its literal sense, is the recycling of obsolete recyclable waste materials into manufacturing processes as raw materials through various recycling methods. We can say that a lot of waste is generated in environmental and industrial terms. Sunflower (Helianthus annus L.) is one of the major oil crops grown in the world for the production of edible and biodiesel oil. A large number of plant and raw material wastes, especially those used in food products, are recycled into cleaning, health, cosmetic and industrial products. In this study, the cold-pressed oil and pulp obtained from the seeds of the sunflower plant were evaluated and transformed into an added-value cosmetic product. Especially the fact that it contains other valuable compounds such as phenolic compounds, fatty acids, fibers, vitamins, minerals and polyphenols increases the popularity of the value-added product. Within the scope of our work, we produced two value-added products. These products are creams containing sunflower oil, which has nourishing, moisturizing and protective properties and the other product is a skin mask containing sunflower pulp. As our university specializes in added-value agricultural products, our product production is increasing day by day. © 2024, Jomard Publishing. All rights reserved.
