Abstrak

Exploring sensing mode with new detection signal is of great significance in analytical chemistry. In this study, we introduce a new sensing mode that employs the deformation of liquid crystal (LC) droplets as a new detection signal. As a proof-of-concept, we fabricated SDS-coated liquid crystal (LC) droplets, where the degree of deformation shows a positive correlation with the concentration of the target analyte, lead ions (Pb2+). The limit of detection (LOD) for Pb2+ was determined to be 106.4 μg/mL, which is lower than the other metal ions. It is worth noting that preliminary experimental results demonstrate that other surfactants (such as sodium alpha-olefin sulfonate, AOS) and organic phase (such as vegetable oil) also could be employed to fabricate the droplets and show different response to metal ions, which show high flexibility of the as-proposed detection method.
