 A Schematic of combination of ¹³¹I-ELP brachytherapy and ELP-K12/CpG immunotherapy. I.T. retention of CpG delivered with or without an ELP depot over time. Compared with the control group, ¹³¹I-ELP effectively inhibited tumor growth. (Reproduced with permission from Ref. [117] Copyright 2022, Elsevier B.V.) B Schematic representation of F-TRAP assembly, drug release by ¹⁹ F MRS and zero-echo time (ZTE) for ¹⁹ F MRI. Both F-TRAP-Dox or TRAP-Dox can achieve drug release similar to that of free Dox. Cell viability assay for F-TRAP-Dox, Dox and F-TRAP at 37 °C. (Reproduced with permission from Ref. [115] Copyright 2019, American Chemical Society)
