The researchers exploit exciton-to-trion conversion in ångström-thick semiconductors for all-optical detection of electrical activity in cardiomyocyte cultures. This approach affords high temporal resolution and paves the way for elusive label-free all-optical voltage-sensing applications of two-dimensional semiconductor materials in the biological domain.
