Fig. 2. HPMA copolymer delivery two hours after treatment.
Laser treatment of the right tumor in animals previously administered GNRs (PPTT) facilitated significant enhancement of HPMA copolymer delivery in terms of both accumulation and overall tumor distribution (A, top row). Laser alone did not cause any increased delivery (A, bottom row). A 3D surface plot provides better visualization of this effect at a single slice (B).
