Abstract
A detection system includes a detection device and an anti-evaporation device. The detection device comprises a region configured to merge at least two small drops and to detect a potential transient signal generated by the merger of the drops. The an anti-evaporation is configured to enclose the region and limit evaporation from the region. A method for detecting a signal includes the following steps: depositing drops of potentially reactive chemical solutions on a detection device within a drop-merging region; placing an anti-evaporation device over the drop-merging region to form a seal around the drop-merging region; merging the drops of potentially reactive chemical solutions; and measuring a signal occurring within the merged solution drops.
