Cold sintering of vaterite microspheres incorporated with GFP-modified Escherichia coli under gigapascal-level pressure for enhanced mechanical properties and stable fluorescence

Key Points

• Enhanced mechanical properties were observed with vaterite microspheres incorporated with GFP-modified E. coli under gigapascal-level pressure.
• The incorporation of GFP-modified E. coli contributes to stable fluorescence in the microspheres, enhancing their functionality.
• Cold sintering techniques were employed to achieve desirable properties in the microspheres while preventing degradation of the incorporated cells.
• This approach may facilitate innovative applications in biocompatible materials and sensors, though further validation is required.
