A technique called Ba-tagging is being developed as a potential future upgrade for nEXO to detect the $^{136}$Xe double-beta decay daughter isotope, $^{136}$Ba. An efficient Ba-tagging technique has the potential to boost nEXO's 0$\\nu\\beta\\beta$ sensitivity by essentially suppressing non-double-beta decay background events.
