Abstract

original image

Two-dimensional bio-dynamite: Chemically exfoliated MoS2 (ceMoS2), a water-dispersible sheet-like material, is an efficient near-infrared (NIR) photothermal transducer. The superior bio-supramolecular properties of ceMoS2 and the ability of this material to destroy biomolecular targets through near-infrared (NIR) photothermal transduction were studied (see picture).
