    Abstract:
    Developing safe and effective stimuli-responsive nanocarriers is very important for tumor chemotherapy. In this work, bovine serum albumin (BSA) and green tea polyphenol (TP) were used to prepare glutathione (GSH) and enzyme (trypsin) responsive nanocarriers for doxorubicin (DOX). These nanocarriers were further modified with folate, briefly named as DOX@BSA-TP-FA NSs. The diameter of nanocarriers was about 220 nm. The DOX loading efficiency and loading amount were 86.4% and 23.5 wt%, respectively. The cellular uptake, apoptosis, and GSH and trypsin responsive release properties of these nanocarriers were investigated.
