Rapid and accurate tumor-target bio-imaging through specific in vivo biosynthesis of a fluorescent europium complex.

Abstract

A new and facile method for rapidly and accurately achieving tumor targeting fluorescent images has been explored using a specifically biosynthesized europium (Eu) complex in vivo and in vitro. It demonstrated that a fluorescent Eu complex could be bio-synthesized through a spontaneous molecular process in cancerous cells and tumors, but not prepared in normal cells and tissues. In addition, the proteomics analyses show that some biological pathways of metabolism, especially for NADPH production and glutamine metabolism, are remarkably affected during the relevant biosynthesis process, where molecular precursors of europium ions are reduced to fluorescent europium complexes inside cancerous cells or tumor tissues. These results proved that the specific self-biosynthesis of a fluorescent Eu complex by cancer cells or tumor tissues can provide a new strategy for accurate diagnosis and treatment strategies in the early stages of cancers and thus is beneficial for realizing precise surgical intervention based on the relevant cheap and readily available agents.
