Other techniques such as elemental analysis, electrochemical, and thermal methods were also employed for the assessment of the complexation ratio. There are a number of ways in which coordination compounds are used in the analysis of various substances. It is noteworthy to mention that in vivo these ligands will compete for a particular metal ion with a variety of other ligands determining that the extrapolation of this in vitro behavior should be done with moderation. Their interesting optical, magnetic, radioactive, and other properties enable their use in many non-invasive and quick methods: e.g., optical imaging, magnetic resonance imaging (MRI), and positron emission tomography (PET).
