Fig. 3From: Targeted delivery of pentagalloyl glucose inhibits matrix metalloproteinase activity and preserves elastin in emphysematous lungsA IVIS fluorescent images of mice lungs 6Â weeks after inhaling DiR NPs and ELN-DiR NPs. Elastin antibody conjugated nanoparticles are retained more than unconjugated controls.
