“…Moreover, PhCs are combined with many technologies to improve its selectivity and sensitivity, such as surface plasmon resonance (SPR) (Gupta et al, 2016 ; Huang et al, 2020 ; Islam et al, 2020 ; Wang et al, 2020 ), surface-enhanced raman scattering (SERS) (Beffara et al, 2020 ; Dedelaite et al, 2020 ; Kraai et al, 2020 ; Wang et al, 2021 ), etc. Molecular imprinting technology (MIT) when combined with PhC sensor can be used to create biomimetic materials with specific recognition sites (Huang S. Y. et al, 2018 ; Zhao et al, 2018 ).…”

Photonic crystals (PhCs) with a brightly colored structure are novel materials and are widely used in chemical and biological sensing. Combining PhCs with molecular imprinting technology (MIT), the molecularly imprinted PhC (MIPC) sensors are fabricated, which can specifically recognize the target molecules. Aside from high sensitivity and selectivity, the MIPC sensors could recognize the naked eye detection because of its optical properties. In this review, an overview of recent advances in sensing applications of MIPC sensors including the responsive mechanisms, application in environmental monitoring, and the application to human health were illustrated. The MIPC sensors all responded to the analytes specifically and also showed high sensitivity in real samples, which provided a method to realize the rapid, convenient, naked eye, and real-time detection. Furthermore, the current limitations and potential future directions of MIPC sensors were also discussed.
