Selective photothermal effect of a pulsed laser in cultured cells with Ti3C2Tx MXenes

Abstract

MXenes is a large family of 2D transition metal carbides and/or nitrides derived primarily through the selective etching of the A-group element layers in layered ternary transition metal carbides and/or nitrides (MAX phases) [1]. MXenes strongly absorb light in the near-infrared (NIR) spectrum, including in physiological NIR window (650 to 1350 nm); and possess a high photothermal conversion efficiency [2]. Because of that, they show a high potential for development of minimally invasive anti-cancer treatment via a photothermal therapy approach (PTT) [3].
