Near-infrared radiation
for remote activation
of muscle cells

Researchers developed a new method for remotely inducing contraction of skeletal muscles, and and possibly deep tissues, by mildly heating gold nanoshells with near-infrared radiation. Calcium fluxes which damage muscle cells and are observed in usual physiological contraction did not occur in the process. This techinque is currently being adopted in several clinical applications, including cancer therapy and neural cell stimulation.

The research appeared online on ACS Nano by the American Chemical Society. It was also introduced in the news and views section of Nature Publishing Group’s Nature Nanotechnology.
