Motion-induced change in emission (MICE) for developing fluorescent probes.

Area of Science:

• Chemical Sensing
• Fluorescent Probes
• Molecular Spectroscopy

Background:

• Developing fluorescent probes for detecting environmental and biological analytes is crucial.
• Molecular motions in flexible probes are sensitive to micro-environments and analytes, affecting signals.
• Existing sensing mechanisms like PET, ICT, AIE, and DIE are well-established, but MICE is underexplored.

Purpose of the Study:

• To systematically review the concept and mechanisms of Motion-Induced Change in Emission (MICE).
• To highlight the advantages and applications of MICE-based fluorescent probes.
• To discuss current technical challenges and future directions in MICE probe development.

Main Methods:

• Literature review and conceptual analysis of MICE in fluorescent sensing.
• Comparison of MICE with established sensing mechanisms (PET, ICT, AIE, DIE).
• Summarization of MICE probe design, advantages, applications, and challenges.

Main Results:

• MICE is presented as an effective sensing mechanism leveraging analyte-induced changes in molecular motion.
• MICE offers unique advantages for developing sensitive and selective single-molecular fluorescent probes.
• Diverse applications of MICE-based sensors are demonstrated across various fields.

Conclusions:

• MICE provides a powerful, yet under-discussed, platform for fluorescent sensing.
• Further research into MICE can lead to the development of advanced fluorescent probes.
• This review aims to foster a deeper understanding and encourage innovation in MICE-based sensing.
