Safety |
No GMOs will be released, and therefore there is no biosafety
issue. |
[48, 66] |
Toxicity tolerance |
The system can operate in the presence of toxins. |
[67] |
Response time |
The tested materials can react directly with the sensors
in a cell-free environment to generate signals more quickly. |
|
Selectivity |
It has the selectivity based on biosensor elements, which
can reduce the interference with other signals. |
[51] |
Stability |
Cell-free systems have high long-term storage stability by
the freeze-drying technology. |
|
Sensitivity
(Detection limit)
|
The detection sensitivity is high; the detection limit is low and can
even reach the nanomole level.

|
Robustness |
Cell-free system can keep its structure and function stable
when it is disturbed by uncertain factors. |
[69] |
Engineering operation |
Metabolic pathways can be simplified and
optimized by adding different concentrations of DNA components or by
mixing different cell extracts. |
