A method for the selective fluorescence sensing of homocysteine (Hcy) and cysteine (Cys) under neutral pH conditions, based on the reaction of the simple aldehyde containing Bodipy dye with Hcy/Cys, has been developed. The location of the aldehyde group at the Bodipy core is important and has an effect on the cyclization with Hcy/Cys.
Herein, a novel, fusiform-like magnetic metal–organic framework material (Fe 3 O 4 -NH 2 @MOF-235) was fabricated by a facile two-step solvothermal approach.
