Abstract

A hydrophilic‐hydrophobic patterned molecularly imprinted (MIP) photonic crystal (PC) sensor is fabricated for highly sensitive tetracycline detection. The relationship between the tetracycline concentration, its corresponding color of the sensor, and the diameter of MIP‐PC dot is found using a fan‐shaped color card. This work provides a new strategy to design the sensors with tunable detection ranges for practical applications.
