New method for developing tracers used for medical imaging
- yomly 7y agoFor any chemists out there - the tl;dr is that the chemists worked out how to break C-H bonds and replace them with a radioactively labeled C-18F bond for on aromatic rings which is pretty cool. The molecule can then be traced through the body using PET It'll be interesting to know how labelling of F would affect the chemistry of a compound - F is a fairly nice choice given that it is quite small so shouldn't introduce much steric difference. That said, F far more electronegative than H which could affect some degree of solubility and possibly the reactive site if it is closely situated.
- DoctorOetker 7y agoHas mercury ever been used as a radio tracer to trace thiomersal in the human body? Many of the mercury isotopes pass through gold isotopes, so I would expect gold to be relatively inert an inocuous, so it boils down to selecting suitable mercury isotopes for suitable halflife timescales (the halflife of the mercury isotope candidate to trace it, and the halflife of the gold daughter nucleus so as to remain gold throughout the test subject's lifetime)
