Area of Science:

• Materials Science
• Nanotechnology
• Pharmacology

Background:

• Drug delivery systems are crucial for reducing toxicity and enhancing therapeutic efficacy.
• Conventional carriers include polymeric carbohydrates, synthetic proteins, and liposomes.
• Developing advanced carriers remains a key focus in pharmacological research.

Purpose of the Study:

• To investigate surface-modified nanocrystalline ceramics as a novel drug delivery system.
• To evaluate the potential of these carriers for improved drug stabilization and targeted delivery.
• To demonstrate the efficacy of this new carrier class in preclinical applications.

Main Methods:

• Developing surface-modified nanocrystalline ceramic carriers.
• Non-covalent binding of pharmacological agents to a glassy stabilization film on ceramic surfaces.
• Testing the delivery of viral antigens, oxygenated hemoglobin, and insulin.
• Evaluating drug activity, structural integrity, and cellular targeting post-delivery.

Main Results:

• Surface modification of nanocrystalline ceramics created a stable, glassy molecular film.
• Pharmacological agents bound non-covalently with minimal structural denaturation.
• Preserved drug activity and enhanced cellular targeting were observed.
• Successful delivery of viral antigens, oxygenated hemoglobin, and insulin was demonstrated.

Conclusions:

• Surface-modified nanocrystalline ceramics represent a promising new platform for drug delivery.
• This approach maintains drug integrity and enhances therapeutic outcomes.
• Offers potential for reduced toxicity, improved targeting, and extended shelf-life.
