Abstract: The present invention describes methods for obtaining functionalized polymeric surfaces (MPn-PSm) from polymers or copolymers with appropriate functionalizations (X), which can be a halogen of a leaving group, such as polyvinyl chloride (MP1) and (chloromethyl)polystyrene-Merrifield (MP2), and curcumin photosensitizers (PS1), meso-tetra(aryl)porphyrins, chlorins or bacteriochlorins halogenated and functionalized with nucleophilic groups (PS2), in particular including P2 of the type meso-imidazoyl-porphyrins, chlorins or bacteriochlorins (PS3). The structures of all the photosensitizers in the present application incorporate a functional group (Y), which is a OH, SH or NH2nucleophile. The application also describes the covalent bonding process of the photosensitizers PS1-PS3 to the functional polymeric materials MP1-MP2 by means of a nucleophilic substitution reaction to prepare the MPn-Psm products.

Abstract: Disclosed are apparatuses and methods for irradiating a perfusate. The apparatus includes a tank which defines a first chamber. A separator is located inside the first chamber. The separator defines a second chamber. The first chamber and the second chamber are concentric and have substantially annular cross sections, each having at least one diameter and a substantially common longitudinal axis. A perfusate is introduced into the first chamber by an inlet. A UV radiation-emitting device is disposed inside the second chamber for providing irradiation to the perfusate. Irradiated perfusate is removed from the tank by an outlet. Other apparatuses and systems are described and methods for inactivating micro organisms by performing EVP and irradiating the perfusate.
