(A) Release profiles of SF-coated NPs (■) Lim@MSN/SF and (●) Lim@P-PMO/SF under isothermal TGA conditions (30 °C, a N₂ flow at 1.0 mL min⁻¹). The samples were obtained by dipping Lim@MSN or Lim@P-PMO (LC = 38 ± 1%) in a 4% (w/v) silk fibroin solution (25 °C, 1 min) followed by freezing and lyophilization. (B) Change in weight of mangoes with different coatings and uncoated samples during storage at ambient temperature 30–35 °C and 75–85% RH. Right panel: visual appearance of mango samples during storage, respectively, coated with (a) SF, (c) P-PMO/SF, (d) Lim@P-PMO/SF, and (b) without coating as a control. Error bars represent the standard deviation.
