text: Yo, check it out, listen up, here's the scoop,
  Camptothecin, a drug broad-spectrum, that's the truth,
  Used in clinics, fighting cancer, it's been proven,
  But hydrophobic properties, yeah, they're a problem, movin'.
  
  So we came up with a plan, synthesized a mix,
  Fe3O4@poly(vinylpyrrolidone), acid-degradable tricks,
  Gold nanoclusters, yo, they got mad fluorescence,
  Fe3O4@PVP, photothermal essence.
  
  Combined 'em all, Zeolitic Imidazolate Framework-8,
  Composite nanoparticles, yeah, they're straight,
  Loaded 'em up with CPT, efficient carrier,
  Cell imaging, photothermal, yo, it's all in there.
  
  Modified the surface, with folic acid-grafted BSA,
  Targeting them tumor cells, that's the way,
  Once they get inside, hit 'em with infrared light,
  Chemo-photothermal effect, it's a fight.
  
  These nanoparticles, they bring the heat,
  Effective against tumors, they can't be beat,
  So you see, this ZIF-8 nanocomposite,
  Got potential for cancer treatment, that's legit.
