Abstract: Described herein are methods for imaging a fluorescent bioassay (including a substrate, such as dispersed cellular sample, exposed to one or more exogenous fluorophore and/or fluorescent probe that accumulate in a structure of interest). The bioassay can be excited with Type-C ultraviolet (UVC) light produced by one or more light emitting diode (LED). The UVC can have a center wavelength that causes emission by the fluorescent bioassay. A digital optical device can collect a signal emitted from the fluorescent bioassay in response to the excitation. The methods relate in particular to Microscopy with Ultraviolet Surface Excitation (MUSE) imaging.

Abstract: A two-stage treatment process for destroying per- and polyfluoroalkyl substances (PFAS) in an aqueous stream. The two-stage treatment process uses a combination of multifunctional crystalline molecular sieves, such as zeolites and zeotypes, to separate PFAS from the aqueous stream, catalytically decompose and defluorinate any PFAS molecules, and generate non-toxic waste products that are safe for disposal. The first stage includes adsorption of the PFAS within one of a pair of vessels containing porous, hydrophobic, hydrothermally stable molecular sieves, dehydration of the captured PFAS on the sieves, and catalytic ozonation of the captured PFAS molecules on the dried sieves. The second stage involves catalytic decomposition and neutralization of the ozonation results with one of a pair of vessels including a zeolite-supported CaO catalyst, catalytic oxidation of any toxic CO generated by the decomposition, and an acid wash for regeneration of the spent catalyst.
