TTA-UCNP composed of BSA–dextran stabilized oil droplets, co-loaded with PtTPBP and BDP dyes. A) The schematic illustration of TTA-UCNP composed of PtPBP (sensitizer) and BDP dyes (annihilator). The BSA–dextran stabilized oil droplets system enhanced the solubility of encapsulated agents. B) In vivo (top) and in situ (bottom) lymph node upconversion luminescence imaging of living mice at 30min after intradermal administration with the TTA-UCNP through paws (BDP-G for the forepaw and BDP-Y for the hindpaw).
