 microfluidics paper

 

 from Korea, using caffeine orange microfluidics detector

 exhibits a 250-fold fluorescence enhancement upon caffeine activation and high selectivity responding to caffeine analogs that have similar chemical structures.

This research was supported by the Singapore-Peking-Oxford Research Enterprise and Word Class University program, and Basic Science Research Program through the National Research Foundation (NRF) by the Ministry of Education , Science and Technology in Korea.
