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.

Abstract: The present invention relates to a kit for detecting a virus, a composition for detecting a virus and a method for detecting a virus. According to the present invention, viruses may be detected with high efficiency at low cost within a short period of time.

Abstract: The present invention relates to an amphiphilic nanoparticle specific to a biomarker, and more particularly, provides an amphiphilic nanoparticle which may be used as a diagnosis or treatment-type drug or gene carrier by selectively recognizing a proteolytic enzyme specifically expressed in a cellular membrane of a specific cell, and then being bound to the proteolytic enzyme to efficiently achieve the intracellular uptake and selective cleavage. The amphiphilic nanoparticle of the present invention may be used in the diagnosis or therapy of a disease.

Abstract: The present invention relates to a method for separating multiple biological materials using characteristics of magnetic nanoparticles. The method of the present invention is able to separate multiple biological materials at once due to differences in trajectory in an external magnetic field of the same intensity after attaching magnetic nanoparticles to the biological materials to be separated using differences in magnetic susceptibility or magnetization depending on compositions of the magnetic nanoparticles.
