Background:

• Collagen is a key biomaterial for tissue engineering and cell culture.
• Developing advanced collagen-based materials with improved properties is crucial for biomedical applications.
• Platinum complexes are known for their anti-cancer properties and potential in material science.

Purpose of the Study:

• To synthesize a novel cross-linked collagen material using platinum complex derivatives.
• To evaluate the physical properties, cell compatibility, and pH-responsive behavior of the new material.
• To explore the potential applications of this platinum-containing collagen gel (PCG) in cell culture and medical injections.

Main Methods:

• Synthesis of platinum-containing collagen gel (PCG) by mixing collagen with cisplatin or transplatin derivatives.
• Characterization of PCG's physical strength and transparency.
• Assessment of PCG's suitability as a 2D and 3D cell culture scaffold, including cytotoxicity evaluation.
• Investigation of PCG's pH-responsive gel-forming properties for controlled material processing.

Main Results:

• PCG demonstrated superior physical strength and transparency compared to native collagen gel.
• PCG showed low cytotoxicity and versatility as a scaffold for both 2D and 3D cell cultures.
• The material exhibited pH-responsive gelation, allowing for purification of the cross-linker.
• The synthesis involves simple mixing of collagen and platinum complex derivatives.

Conclusions:

• A novel platinum-containing collagen gel (PCG) was successfully synthesized.
• PCG offers enhanced material properties and biocompatibility for cell culture applications.
• The pH-responsive nature of PCG provides a method for purification and controlled gel formation.
• PCG shows significant potential for use in cell culture scaffolds and medical injections.
