Drastic Impact of Donor Substituents on Xanthenes in the PDT of Glioblastoma Karaman, Osman; Yesilcimen, E.; Forough, M.; Elmazoglu, Z.; Günbaş, Emrullah Görkem (2025-10-01) Even though significant progress has been made in treating various cancer types, brain cancers lag drastically. Several factors contribute, led by operational difficulties, the blood-brain barrier, and the tendency of recu...
Functionalized Phenyl Methanaminium Salts Provide Highly Stable Perovskite Solar Cells Yaşa, Mustafa; Celik, Esra Bag; Gao, Xiao-Xin; Karabağ, Zeynep Gözükara; Gunes, Ummugulsum; Syzgantseva, Olga A.; Syzgantseva, Maria A.; Zhong, Liping; Züttel, Andreas; Dyson, Paul J.; Nazeeruddin, Mohammad Khaja; Toppare, Levent Kamil; Yerci, Selçuk; Günbaş, Emrullah Görkem (2025-03-01) One of the leading approaches to enhancing the performance and stability of perovskite solar cells (PSCs) involves passivating the perovskite surface and grain boundaries with large ammonium salts. Here, we report the synt...
Self-Assembled Superacid Monolayers on c-Si Provide Exceptional Surface Passivation and Low Contact Resistivity Ghasemi, Milad; Maden, Cem; Bektaş, Gence; Tsoi, Konstantin; Günbaş, Emrullah Görkem; Toffoli, Hande; Yerci, Selçuk (2025-01-01) Minimizing surface recombination is crucial for enhancing silicon solar cell passivation. Conventional dielectric materials require vacuum deposition and high-temperature annealing, increasing complexity and cost. This stu...
NIR-ACTIVATED SILICON-RHODAMINE BASED PHOTOSENSITIZER AS A PROMISING THERAPEUTIC AGENT AGAINST GLIOBLASTOMA Özoğul, Naz; Karaman, Osman; Elmazoğlu, Zübeyir; Günbaş, Emrullah Görkem (2024-11-01) Objectives: Glioblastoma multiforme (GBM) remainsone of the most aggressive malignant tumors inthe central nervous system with low survival rate. Insufficientstandard care of the disease provoked needfor an alternative tre...
Photodynamic Therapy against Glioblastoma: Investigating phenoselenazine based photosensitizer as a promising therapeutic agent Yeşilçimen, Elif; Karaman, Osman; Elmazoğlu, Zübeyir; Günbaş, Emrullah Görkem (2024-11-01) Objectives: Glioblastoma Multiforme (GBM) is themost aggressive malignant brain tumor. Photodynamictherapy (PDT) is a promising treatment strategyagainst GBM. It exerts cytotoxic effect by producingROS, mainly singlet oxyg...
