19194903-0	2008	Polyethylenimine-coated albumin nanoparticles for BMP-2 delivery.	Polyethyleneimine	0-16	bone morphogenetic protein 2	Mus musculus	50-55	
19194903-3	2008	Different concentrations of PEI were utilized for coating BSA NPs to stabilize the colloidal system and to control the release of BMP-2.	Polyethyleneimine	28-31	bone morphogenetic protein 2	Mus musculus	130-135	
19194903-8	2008	The results indicated that PEI was the primary determinant of NP toxicities, and BSA NPs coated with 0.1 mg/mL PEI demonstrated tolerable toxicity, retained the bioactivity of BMP-2, and efficiently slowed the release rate of BMP-2.	Polyethyleneimine	111-114	bone morphogenetic protein 2	Mus musculus	176-181
