Graphical Abstract

Carbon nanohorns were functionalized with a dye to develop a new type of light-driven nanomodulator. This system generates heat and reactive oxygen species (ROS) under biologically transparent near-infrared (NIR) laser irradiation. These properties can be applied for single-cell analyses and innovative cell therapies.

Abstract

A single organism comprises diverse types of cells. To acquire a detailed understanding of the biological functions of each cell, comprehensive control and analysis of homeostatic processes at the single-cell level are required. In this study, we develop a new type of light-driven nanomodulator comprising dye-functionalized carbon nanohorns (CNHs) that generate heat and reactive oxygen species under biologically transparent near-infrared (NIR) laser irradiation. By exploiting the physicochemical properties of the nanohorns, cellular calcium ion flux and membrane currents were successfully controlled at the single-cell level. In addition, the nanomodulator allows a remote bioexcitation of tissues during NIR laser exposure making this system a powerful tool for single-cell analyses and innovative cell therapies.
