Abstract
The unique optical properties of the fluoropolymer microcapillary film (MCF) material combined with the extremely fast photoinactivation of Herpes HSV-1 virus, and photodegradation of indigo carmine, diclofenac and benzoylecgonine in the MCF array photoreactor, demonstrate a new, flexible and inexpensive platform for rapid photochemical transformations, high-throughput process analytics and photochemical synthesis.
Highlights
Photochemical transformation, including the treatment of fluids with ultraviolet light especially of wavelength lower than 280 nm (UVC), has been in practice for many decades, with the first publication reported by NIH in 1949.1 Since several studies have shown that UVC is very effective in e.g. the inactivation of bacterial cells and virus particles,[2] the photodegradation of pharmaceuticals and other contaminants of concern,[3] and the photochemical synthesis of chemical species.[4]
The microcapillary film (MCF) photoreaction system (Fig. 1) is made of a flat fluoropolymer ribbon containing an array of microcapillaries running along it, usually in the range of 10 mm up to 1 mm internal diameter, which are irradiated by a source of light
We demonstrate these capabilities with a range of applications, including the fast photoinactivation of a highly contagious enveloped Herpes HSV-1 virus particles, the fast decolourization of a dye and the photodegradation of contaminants of emerging concern including a pharmaceutical compound and a class I drug metabolite
