Fig. 2: Characterization of enzyme@IP synthesized with different types and amounts of organosilanes.

a SEM images of enzyme@IP synthesized with various organosilanes: a₁ trimethoxysilane (TMS), a₂ tetramethoxysilane (TMOS), a₃ trimethoxymethylsilane (MTMS), and a₄ trimethoxyoctylsilane (OTMS). b Log P values of various organosilanes (P represents the partition coefficient of compound between oil and water) and the corresponding SEM images of enzyme@IP synthesized using each organosilane. The shading represents the region where 0 <Log P <1. c SEM images showing the different shell thickness of enzyme@IP at various MTMS concentrations: c₁ 0.15 g mL⁻¹, c₂ 0.3 g mL⁻¹, c₃ 0.45 g mL⁻¹, and c₄ 0.6 g mL⁻¹. d Fluorescence intensity of rhodamine B diffusion into the interior of enzyme@IP over time at different shell thicknesses.
