Abstract

In this study, we report the photo-induced electron transfer (PET) on parchment paper using riboflavin as a photo inducer and ultraviolet lamp (362 nm) as the light source. To this end, a conventional inkjet printer equipped with 4 cartridges was used. Parchment paper was found to be a favorable substrate due to its insignificant self-absorption while assisting efficient sample interaction. Upon UV-irradiation, riboflavin generated superoxide anion radical (O
