At this stage of the experiment, the strain has never been taken out of the laboratory. The entire sensor system we expect to design will work in the wild environment, but our strains will only be kept in the sensor system and will not be released into the field, so as to ensure that it does not cause animal, plant and environmental safety problems. We will also carry out a strict sterilization process after field work is completed to ensure maximum safety.</div>
