text: Yo, check it, we've been diggin' deep
  Explorin' nanoformulations, makin' drugs seep
  Water-insoluble, we gotta find a way
  But these exotic materials, they causin' delay
  
  Amphiphilic block copolymers, they're the name
  But first, clinical trials, gotta earn that fame
  Approved as drug excipients, that's the game
  Before we can use 'em, they gotta pass the flame
  
  But hold up, we got a hypothesis, a new plan
  Let's use clinical drugs, give 'em a hand
  As surfactants, they'll self-assemble, no doubt
  Solubilize hydrophobic drugs, we'll figure it out
  
  Introducin' irinotecan hydrochloride, so fly
  CPT11, an anti-tumor drug, oh my
  It self-assembles with SN38, the parent one
  Stable nanoparticles, water-dispersible, it's begun
  
  Water solubility of SN38, it's off the charts
  Thousands of times increased, shootin' for the stars
  25 mg/mL, that's the concentration we see
  With a loadin' efficiency close to a hundred, believe me
  
  But wait, there's more, we ain't done yet
  This approach is versatile, we won't forget
  CPT11 with paclitaxel and camptothecin too
  Nanodispersions, increasin' bioavailability, it's true
  
  Anti-cancer activities, they're gettin' a boost
  With these nanodispersions, we're cuttin' loose
  No need for new materials, we're keepin' it real
  Using proven drugs as excipients, that's the deal
  
  Translational nanoformulations, we're breakin' through
  Deliverin' hydrophobic drugs, that's what we do
  So remember this strategy, it's the ultimate key
  No new materials, just amphiphilic drugs, you see
