4 Applications
At present, we are all faced with the situation of frequent
environmental pollution and human diseases. All kinds of environmental
pollutants and diseases seriously threaten the living environment and
health of human beings. To detect these hazards more quickly and
accurately, biosensors with low cost and high efficiency are urgently
needed. In this context, cell-free biosensors have made remarkable
achievements in the rapid detection of environmental pollutants and
disease pathogens (Fig. 4).
