The fusion of biology and technology was used to control blood sugar levels in mice with diabetes.
The idea, described in Science Translational Medicine, could be applied to a wide range of diseases and drug treatments.
And the Chinese researchers say the approach could pave the way for a "new era" in medicine.
The first step was to turn normal cells into living factories.
They were genetically engineered to manufacture drugs that control blood sugar levels such as insulin but only in response to light.
