Figure 2From: Porous silicon nanoparticles for cancer photothermotherapy Comparison of photothermal property between solid PSi, PSi/EtOH:PEG solution (0.7 g/L), and EtOH:PEG solution. ΔT 1 and ΔT 2, respectively, in this graph represent the temperature rises in solid PSi (a free-standing PSi layer) and PSi/EtOH:PEG solution upon NIR laser irradiation at 1.5 W/cm2.Back to article page
