Figure 5From: A comparative in vitro evaluation of self-assembled PTX-PLA and PTX-MPEG-PLA nanoparticlesIn vitro release profiles of PTX-MPEG-PLA NPs versus PTX-PLA NPs in PBS (1/15 M, pH 7.4). The blue line represents the second phase of burst release. The purple arrows showed their burst start and endpoint.Back to article page
