Aggregation-Induced Emission (AIE) Probe-Labeled Nanotheranostics: A Mini-Review

Area of Science:

• Biomedical Engineering
• Materials Science
• Nanotechnology

Background:

• Nanotheranostics combine diagnosis and therapy on nanoscale platforms for precision medicine.
• Traditional fluorescent probes suffer from aggregation-caused quenching (ACQ), limiting imaging.
• Aggregation-induced emission (AIE) agents enhance fluorescence upon aggregation, solving ACQ issues.

Purpose of the Study:

• To systematically review nanotheranostic systems utilizing AIE agents.
• To discuss AIE probe design strategies and disease-specific applications.
• To analyze challenges and future directions for AIE nanotheranostics in clinical practice.

Main Methods:

• Review of literature on AIE mechanisms and nanotheranostic applications.
• Categorization of AIE nanoprobes based on nanocarrier types (liposomes, polymer nanoparticles, self-assembling systems).
• Emphasis on disease-specific AIE nanotheranostic designs for tumors, neurodegenerative, and inflammatory diseases.

Main Results:

• AIE agents provide a superior alternative to traditional fluorescent probes due to their unique emission properties.
• Diverse nanocarrier strategies enable effective loading and function of AIE probes.
• Tailored AIE nanotheranostics show promise for specific pathological microenvironments.

Conclusions:

• AIE nanotheranostics offer significant advantages for advanced imaging and therapy in precision medicine.
• Overcoming challenges in clinical translation is crucial for realizing the full potential of AIE nanomedicine.
• Future developments in AIE nanotheranostics will drive personalized medicine approaches.
