Abstract
Two-dimensional (2D) molybdenum disulfide (MoS2) nanomaterials are an emerging class of biomaterials that are photoresponsive at near-infrared wavelengths (NIR). Here, we demonstrate the ability of 2D MoS2to modulate cellular functions of human stem cells through photothermal mechanisms. The interaction of MoS2and NIR stimulation of MoS2with human stem cells is investigated using whole-transcriptome sequencing (RNA-seq). Global gene expression profile of stem cells reveals significant influence of MoS2and NIR stimulation of MoS2on integrins, cellular migration, and wound healing. The combination of MoS2and NIR light may provide new approaches to regulate and direct these cellular functions for the purposes of regenerative medicine as well as cancer therapy.
