A [5]Rotaxane-Based photosensitizer for photodynamic therapy
(WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)A [5]rotaxane was synthesized through a catalytically self‐threading reaction in which CB6 serves as a macrocycle and acts as a catalyst for the 1,3‐dipolar cycloaddition reaction between the alkyne substituted porphyrin ... -
Generation, storage and delivery of singlet oxygen by a multifunctional agent
(Bilkent University, 2017-04)Photodynamic therapy (PDT) relies on thephoto sensitized generation of sin- glet oxygen (by consuming dissolved oxygen) within tumortissues whose oxygen level is already low enough to make this treatment self-limiting. In ... -
Highly efficient semiconductor-based metasurface for photoelectrochemical water splitting: broadband light perfect absorption with dimensions smaller than the diffusion length
(Springer, 2020)In this paper, we demonstrate a highly efficient light trapping design that is made of a metal-oxide-semiconductor-semiconductor (nanograting/nanopatch) (MOSSg/p) four-layer design to absorb light in a broad wavelength ... -
Laser photochemical nanostructuring of silicon for surface enhanced raman spectroscopy
(Wiley-VCH Verlag GmbH & Co. KGaA, 2022-07-18)In this work, a novel method of fabricating large-area, low-cost surface-enhanced Raman spectroscopy (SERS) substrates is explained which yields nanostructured surface utilizing laser-induced chemical etching of crystalline ... -
Near-IR absorbing BODIPY derivatives as glutathione-activated photosensitizers for selective photodynamic action
(Wiley-VCH Verlag, 2014)Enhanced spatiotemporal selectivity in photonic sensitization of dissolved molecular oxygen is an important target for improving the potential and the practical applications of photodynamic therapy. Considering the high ... -

UV-induced electrical and optical changes in PVC blends
(Springer, 2001)2-Chloro-polyaniline (2-Cl-PANI) in its non-conducting (emeraldine base, EB) form, prepared by a chemical route, was dissolved together with poly-(vinylchloride) (PVC) in THF for casting into thin (10-50 μm) films. Upon ... -
UV-Vis, IR, and XPS analysis of UV induced changes in PVC composites
(Elsevier, 1999-05-25)PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ...
