An object of the present invention is to provide a fluorescent probe that easily penetrates a cell and is capable of selectively and efficiently detecting singlet oxygen generated in the cell, a singlet oxygen detection agent containing the fluorescent probe, and a singlet oxygen detection method using the fluorescent probe. The fluorescent probe for detecting singlet oxygen comprises a compound having a silicon-rhodamine skeleton and a skeleton that increases the fluorescence of the fluorescent probe after trapping singlet oxygen to be greater than the fluorescence before trapping singlet oxygen, or a salt, hydrate, or solvate thereof.

Fluorescent probe, singlet oxygen detection agent, and singlet oxygen detection method

Various metal oxide mesocrystals can be synthesized in a simple manner by a method for producing a metal oxide mesocrystal, the method comprising the step of annealing an aqueous precursor solution comprising one or more metal oxide precursors, an ammonium salt, a surfactant, and water at 300 to 600&#xb0; C. Composite mesocrystals consisting of a plurality of metal oxides or an alloy oxide can also be provided.
