Area of Science:

• Materials Science
• Biomimetic Engineering
• Optical Materials

Background:

• Understanding the relationship between material morphology and optical properties is crucial for developing advanced functional materials.
• Biomimetic approaches offer a pathway to create complex structures with tunable characteristics inspired by nature.

Purpose of the Study:

• To develop novel biomimetic materials based on barium carbonate-silica (BaCO₃-SiO₂) biomorphs hybridized with organic dyes.
• To visualize and differentiate functional properties arising from distinct microstructures.
• To investigate the optical behaviors, specifically fluorescence and light emission, of these engineered materials.

Main Methods:

• Synthesis of BaCO₃-SiO₂ biomorphs with controlled morphologies (helicoid and conical).
• Hybridization of biomorphs with organic dyes.
• Characterization of microstructures and their optical responses, including fluorescence and visible light emission.

Main Results:

• Helicoid microstructures with curved growth demonstrated multistage fluorescence coding, enabling distinct visual identification.
• Conical microstructures with flat growth exhibited white light emission due to tricolor spectral superposition.
• The study successfully visualized functional differences linked to specific morphologies.

Conclusions:

• Biomimetic BaCO₃-SiO₂-dye hybrids can be engineered to display unique optical signatures based on their growth patterns.
• These materials provide a visual platform for distinguishing between different microstructural architectures and their associated optical functionalities.
• The findings open avenues for designing advanced optical materials and sensors.
