Table 6 Organ distribution at different time points of radiolabelled nanoparticles after oral administration (calculated as percentage of initial radioactivity)

From: Targeting efficacy and anticancer activity of polymeric nanoparticles of SN-38 on colon cancer cell lines

Formulation	Time	Heart	Liver	Spleen	Kidney	Lung	Stomach	Small intestine	Colon and rectum
CsENP	After 2 h	0	0	0	0	0	0.03 ± 0.003	36.1 ± 1.4	1.3 ± 0.1
	After 4 h	0	0	0	0	0	0.01 ± 0.001	13.5 ± 2.4	87.8 ± 0.02
	After 6 h	0	1.4 ± 0.05	0	1.03 ± 0.002	0	0	0	18.2 ± 0.005
	After 20 h	0	1.6 ± 0.09	0.05 ± 0.01	2.3 ± 0.03	0	0	0	0

Data are expressed as percentage released of total radioactivity in nanoparticles administered
The values represent mean ± S.D (n = 3)
