Abstract
A bioenvironment-sensitive nanoparticle including a polymer having complementary charges, a method of manufacturing the same, and a pharmaceutical use of the bioenvironment-sensitive nanoparticle are disclosed. The bioenvironment-sensitive nanoparticle can be useful in stably and effectively delivering a target material such as a drug even when used at a small quantity since the nanoparticle is stable in extracellular environments. Also, the bioenvironment-sensitive nanoparticle can be useful in selectively diagnosing or treating cancer cells since the nanoparticle is specific to environments of the cancer cells.
