Provided is a method for improving fragrance persistence by applying a composition including, as active ingredients: oil; and non-ionic polymers having hydrophobic substituents at both termini thereof. In the composition of the presently claimed subject matter, the non-ionic polymers having hydrophobic substituents at both termini thereof form a flower micelle structure by capturing oil and a fragrance through the hydrophobic substituents, and thus can stably maintain the oil and fragrance and prevent fast volatilization of the fragrance, thereby improving fragrance persistence.

Cosmetic composition for improving fragrance persistence

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.
