a Confocal images of UCNPs/CuxOS@ZIF-pretreated Hela cells reacting with various H2S (0–1 mM). b The corresponding linear relationship of UCL intensity versus H2S concentration. c The CD spectra and d the corresponding linear relationship of ΔCD of UCNPs/CuxOS@ZIF-pretreated Hela cells reacting with various H2S (0–1 mM). Scale bar = 200 µm
