Abstract: A system for ultraviolet irradiation of objects and a method of using this system is disclosed. The system includes: an illuminating device positioned in a center section of an octagon shaped a base area and including one or more elongated light sources, each emitting ultraviolet light given by shortwave ultraviolet light (UV-C light) and extending in parallel to a normal on the base area; a set of rotatable mesh grids arranged around the base area such that the mesh grids surround the illuminating device and configured to be equipped with the objects; and a set of reflectors including a set of movable side reflectors, wherein the reflectors are configured to be arranged such, that they form a resonator surrounding the mesh grids surrounding the illuminating device.

Abstract: A sterile and instantly dissolvable drug membrane, a method thereof for testing drug sensitivity of antineoplastic drugs, and an application thereon in testing drug sensitivity of antineoplastic drugs are provided, wherein the method for testing drug sensitivity of antineoplastic drugs includes steps of: dissolving an antineoplastic drug in a cell culture fluid comprising tumor cells, in such a manner that the antineoplastic drug fully contacts with the tumor cells; wherein the antineoplastic drug is prepared into a sterile and instantly dissolvable drug membrane for being dissolved in the cell culture fluid. According to the present invention, the antineoplastic drug is prepared into a sterile and instantly dissolvable drug membrane for testing drug sensitivity of the antineoplastic drugs, which improves operation efficiency, flexibility, accuracy and economy of drug sensitivity test of the antineoplastic drugs.
