Figure 5From: Anticancer drug-loaded multifunctional nanoparticles to enhance the chemotherapeutic efficacy in lung cancer metastasis DOX concentration in lungs following a single dose inhalation of free DOX, GNP, and EGNP. The DOX concentration in lungs was determined after 0.5, 12, and 24h dose administration. The DOX from EGNP was significantly (p < 0.001) higher than GNP and free DOX. **p < 0.001 is the statistical difference between EGNP and GNP.Back to article page
