In-Depth Analysis of Zn-68: From Stable Isotope to the Cornerstone of “Theranostic” Nuclear Medicine

In-Depth Analysis of Zn-68: From Stable Isotope to the Cornerstone of “Theranostic” Nuclear Medicine BY Tao, Published Jan 2, 2026   Zinc-68 (Zn-68, ⁶⁸Zn) looks unremarkable on a periodic table. It is stable, non-radioactive, and—outside of isotope circles—rarely discussed. Yet in today’s clinical reality, enriched Zn-68 has become one of the most strategically important materials…
