Convertible Organic Nanoparticles for Near‐Infrared Photothermal Ablation of Cancer Cells

Abstract

Infiltrate and destroy: In an environment rich in protonating or oxidative species, such as the intracellular milieu of cancer cells, the main absorption band of spherical, water-soluble polyaniline nanoparticles was red-shifted to a near-infrared (NIR) wavelength as a result of the formation of the emeraldine salt (see picture). The doped nanoparticles caused photothermal ablation of cancer cells upon NIR laser irradiation in vitro and in vivo.
