1. **Bright or Neon Colors:** Avoid overly bright or neon colors that might distract from the clarity of the components in the diagram.
   
2. **Complex Backgrounds or Scenery:** The focus should solely be on the structure of the electrode and its components (HAp, graphite particles, silver ions), without any complex backgrounds or scenic elements.

3. **Human Figures or Biological Tissues:** Exclude any depictions of human figures or biological tissues interacting with the electrode to maintain a clear and focused representation of the electrode structure and materials.

4. **Excessive Detailing:** Avoid unnecessary intricate details that could clutter the image and make it difficult to understand the main components and their interactions.

5. **Abstract or Artistic Interpretations:** Stick to a clear, technical depiction rather than abstract or artistic interpretations that might obscure the scientific details of the electrode structure.

These preferences aim to ensure that the im
