| Popis: | In this work, a biomimetic chip with patterned wettability, capable of harvesting fog and detecting trace molecules in the fog is proposed. Such a chip consists of micropatterns of nanofiber forests on a silicon substrate, and it is prepared using an extremely simple process composed of only photolithography and plasma treatment. Due to condensation-assisted wetting of the superhydrophilic nanofiber forest micropatterns, such a chip can achieve fluorescence analysis of molecules with a concentration down to 10−8 M. It is expected that such a chip can achieve real-time and highly sensitive detection of fog quality in fields of medical diagnosis and environmental monitoring. |
