متن کاملPlasmonic engineering of singlet oxygen generation.
In this article, we report metal-enhanced singlet oxygen generation (ME(1)O2). We demonstrate a direct relationship between the singlet oxygen yield of a common photosensitizer (Rose Bengal) and the theoretical electric field enhancement or enhanced absorption of the photosensitizer in proximity to metallic nanoparticles. Using a series of photosensitizers, sandwiched between silver island film...
متن کاملFRET quenching of photosensitizer singlet oxygen generation.
The development of activatable photodynamic therapy (PDT) has demonstrated a utility for effective photosensitizer quenchers. However, little is known quantitatively about Forster resonance energy transfer (FRET) quenching of photosensitizers, even though these quenchers are versatile and readily available. To characterize FRET deactivation of singlet oxygen generation, we attached various quen...
متن کاملSinglet Oxygen
Singlet oxygen (O2) is a higher energy state molecular oxygen species. It is one of the most active intermediates involved in chemical and biochemical reactions. To fully appreciate the reactivity of O2, it is necessary to understand its physical and chemical nature. This paper reviews the generation, quenching and detection of O2. Its properties, possible chemical reactions are presented as we...
متن کاملSinglet oxygen generation ability of squarylium cyanine dyes
The quantum yields for singlet oxygen generation of several squarylium cyanine dyes derived from benzothiazole, benzoselenazole and quinoline, displaying absorption within the so-called “phototherapeutic window” (600–1000 nm), were determined, envisioning their potential usefulness for photodynamic therapy (PDT). The determination was performed by a direct method measuring the luminescence deca...
