(A) Schematic illustration of the synthesis of UCNPs hCy7 and its sensing to MeHg⁺ with a change in UCL emission. (B) (a) In vivo UCL images of 40 μg hCy7-UCNPs-pretreated living mice injected intravenously with 0.2 mL normal saline (left mouse) or 0.1 mM MeHg⁺ solution (right mouse). (b) The corresponding UCL images of the livers which were isolated from the above dissected mice. The UCL emission was collected at 800 ± 12 nm upon irradiation at 980 nm.
