Cell organelle targeting of near-infrared croconaine dye controls photothermal outcome

Chem Commun (Camb). 2020 Jun 25;56(51):6977-6980. doi: 10.1039/d0cc02612c.

Abstract

Near-infrared croconaine-peptide conjugates that target the cell nucleus promote photothermal induced cell death. In contrast, a croconaine-morpholine conjugate that targets the cell lysosomes promotes lysosome permeabilization without measurable cell phototoxicity.
