Kinetic Data Of OGEOO Release From Chitosan And Trimethyl Chitosan Nanoparticles In Different Physiological pH Mediums (ph 3.0 And pH 7.4)

Samples Zero-Order First-Order Korsmeyer-Peppas Higuchi
r2 K0 r2 K1 r2 KKP r2 KH
OGEO-CSNPs (pH 3.0) 0.792 1.657 0.772 1.746 0.792 1.031 0.565 1.569
OGEO-TMCNPs (pH 3.0) 0.749 1.596 0.624 1.668 0.749 0.983 0.749 1.596
OGEO-CSNPs (pH 7.4) 0.699 1.289 0.661 1.320 0.0014 0.861 0.371 1.200
OGEO-TMCNPs (pH 7.4) 0.557 1.231 0.398 1.142 0.557 0.981 0.001 1.143

Notes: Where the regression coefficient is r2, release rate constant for zero-order is K0, release rate constant for first-order is K1, Korsmeyer-Peppas rate constant is KKP and Higuchi rate constant is KH.
