Lanthanide-based tools for the investigation of cellular environments

Area of Science:

• Inorganic Chemistry
• Biomedical Engineering
• Nanotechnology

Background:

• Lanthanide complexes are valuable biological probes due to their unique luminescence and relaxivity properties.
• Intracellular delivery is crucial for many applications of lanthanide-based probes.
• Existing methods focus on non-targeted uptake or targeted delivery via peptides or small molecules.

Purpose of the Study:

• To review current methods for intracellular delivery of lanthanide probes.
• To discuss techniques for confirming intracellular localization and tracking probe fate.
• To explore potential new delivery strategies for lanthanide probes.

Main Methods:

• Review of literature on non-targeted and targeted intracellular delivery of lanthanide complexes.
• Discussion of analytical techniques for intracellular localization (e.g., microscopy, spectroscopy).
• Examination of methods for determining the fate of intracellular probes.

Main Results:

• Categorization of delivery strategies into non-targeted and targeted approaches.
• Emphasis on methods verifying intracellular presence and monitoring probe behavior.
• Identification of successful intracellular delivery techniques for other metal probes that could be adapted for lanthanides.

Conclusions:

• Effective intracellular delivery of lanthanide probes is essential for their biological applications.
• A range of methods exist for delivery and verification of intracellular localization.
• Further exploration of advanced delivery techniques could enhance the utility of lanthanide probes.
