Peptide-Mediated Tumor Targeting by a Degradable Nano Gene Delivery Vector Based on Pluronic-Modified Polyethylenimine

Table 1 Fitting of degradation degree of Pluronic-PEI-DR5-TAT to different kinetic models

Model	Equation	R	Mse
Zero-order kinetic	Q = 0.0125t + 0.1157	0.9743	0.01123
First-order kinetic	ln(1 − Q) = −0.285t + 0.0213	0.9968	0.00056
Higuchi	Q = 0.1058t^1/2 − 0.0047	0.9959	0.00108
