ABSTRACT

Singlet oxygen plays an important role in photodynamic therapy of cancers, photodynamic abortion of
microorganisms and photo oxidation. Herein we exhibit a common platform to improve singlet oxygen production
via resonance coupling between surface plasmon and photosensitizers. Pectin functionalized gold nanoparticle
(AuNPs) were synthesized. The crystalline size of nanoparticles was investigated using powder X-ray diffraction
(XRD) method. The presence of pectin on the surface of gold nanoparticle as visualized from UV-Vis spectra
provided the stability and capping density of polymer on surface of AuNPs. The Fourier transform infrared (FTIR)
spectroscopy of the sample has confirmed the presence of pectin on the surface of AuNPs. The nanoparticle size
was measured utilizing XRD, Dynamic light scattering (DLS). Singlet oxygen generation was observed by photo
luminescence spectrophotometer (PL). By adsorbing photosensitizers into pectin containing gold nanoparticles,
strong resonance coupling between the photosensitizers and the gold nanoparticle enhance the singlet oxygen
generation under UV irradiation. This work establishes a general platform to improve singlet oxygen production
and to develop a more effective and efficient hybrid metal-photosensitizer for photodynamic inactivation of
cancer cells.
