Analyses of the residual percentages and the degradation rate coefficients of RIPND-entrapped ICG and freely dissolved ICG under 4 or 37°C incubation for 48 h.

Treatment†	ICG degradation (%)	Kd (h−1)
RIPND-entrapped ICG
4°C	10.42%∗	0.0060∗
37°C	31.07%∗	0.0156∗
Freely dissolved ICG
4°C	24.28%	0.0190
37°C	70.54%	0.0514

^†Treatments were all performed in the dark. ^∗P < 0.05 compared to the value gained from the group of freely dissolved ICG under the same temperature settings.
