Abstract

Disclosed are a photonic crystal microscope and a method of measuring cellular forces. The photonic crystal substrate includes a photonic crystal substrate, a stage, a probe light source, and an imaging assembly, the photonic crystal substrate being disposed above the stage, the probe light source and the imaging assembly being sequentially disposed at a side of the stage opposite the photonic crystal substrate, the photonic crystal substrate being configured to culture a to-be-measured cell, the photonic crystal substrate being deformable when the to-be-measured cell grows on the photonic crystal substrate; the probe light source is configured to emit probe light to the photonic crystal substrate; the photonic crystal substrate is configured to reflect the probe light to the imaging assembly; the imaging assembly is configured to receive the light reflected from the photonic crystal substrate to perform imaging.
