I can't find the classification in morphology of nab-paclitaxel, so I don't know if this nanoparticles is considered only as a protein nanoparticle or also as a core-shell nanoparticles. Considering that paclitaxel is encapsulated inside the albumin protein structure, I can say that nab-paclitaxel is actually a organic/organic core-shell nanoparticle. I hope some expert can help me.
