Fig 1. Physicochemical characteristics of HA micelle and losartan-HA micelle.

Fig 1

A. Size measurement by DLS and surface charge measurement by zeta potential of HA micelle and losartan-HA micelle in PBS at 7.4 pH. HA micelle and losartan-HA micelle was taken at 100 μg/ml concentration and bath sonicated (Power Sonic410,Hwashin,Korea) for 5 minutes at room temperature and measured; B. TEM image of a SPION loaded HA micelle and SEM image of losartan-HA micelle (inset). The size of losartan-HA micelle was estimated to be around 300nm based on SEM and DLS result whereas the morphology of particle was confirmed from TEM and SEM image.
