Co to jest program Living Materials?

Programmable living materials are composite systems that contain living cells - such as bacteria, yeacht, algae, or mambalian cells - embedded with a structural matrix. The cells are genetically eid to perforom specific tasks in responses te to external cues like chemicals, light, temperatur, or mechanical stress. Thee matrix can a hydrogel, bipolimer, or even a minal scaffold that supports cell viability while provisiing mechanical integral integral.
