Preparation and cell imaging of a nido-carborane fluorescent complex based on multi-component polymerization

Area of Science:

• Materials Science
• Polymer Chemistry
• Nanotechnology

Background:

• Carborane biocompatibility is a significant challenge in materials science.
• Developing water-soluble carborane derivatives is crucial for biomedical applications.

Purpose of the Study:

• To synthesize and characterize novel water-soluble carborane polymers.
• To investigate the cellular uptake and self-assembly behavior of these polymers.

Main Methods:

• Multi-ion inlay binding was used to encapsulate nido-carborane within diazaspirodecaniums.
• Four para- and meta-poly-nido-carboanylazaspirodecanium derivatives (p-PNC54, p-PNC65, m-PNC54, m-PNC65) were synthesized.
• Transmission Electron Microscopy (TEM) was employed to study polymer self-assembly and cellular interactions.
• In vitro cell imaging was used to assess selective cell penetration.

Main Results:

• The synthesized carborane polymers exhibited water solubility and self-assembly characteristics.
• All four derivatives demonstrated selective penetration into HeLa cells.
• TEM analysis revealed the dynamic self-assembling effects of the polymers.
• Comparative analysis showed varying degrees of cell entrance based on polymer architecture.

Conclusions:

• Novel water-soluble carborane polymers were successfully synthesized.
• These polymers display promising self-assembly and selective cellular uptake properties.
• The findings suggest potential applications in targeted therapies and advanced materials.
