Illuminating Sub-Cellular Organelles by Small Molecule AIEgens.

Area of Science:

• Cell Biology
• Biochemistry
• Medical Imaging

Background:

• Sub-cellular organelles are vital for biological processes.
• Organelle dysfunction is implicated in diseases like cancer and metabolic disorders.
• Understanding organelle dynamics is key for disease treatment.

Purpose of the Study:

• To review novel small molecules with aggregation-induced emission (AIE) properties.
• To highlight AIEgens for imaging various organelles.
• To discuss their potential in next-generation therapeutics.

Main Methods:

• Review of small molecules exhibiting aggregation-induced emission (AIE).
• Focus on molecules with restriction in intramolecular motion (RIM).
• Examples of AIEgens targeting specific organelles.

Main Results:

• Identification of novel small molecules with AIE properties.
• Demonstration of AIEgens for imaging mitochondria, ER, Golgi, lysosomes, nucleus, cell membrane, and lipid droplets.
• AIEgens show potential for phototherapy.

Conclusions:

• AIEgens are powerful tools for organelle imaging.
• These molecules facilitate the study of organelle dynamics in disease.
• AIEgens hold promise for developing targeted organelle-based therapies.
