摘要:
The present invention relates to a bioprobe including a substrate and inorganic nanoparticles attached to the surface of the substrate, a method of preparing the bioprobe, and an analysis apparatus and method using the bioprobe. In the bioprobe according to the present invention, inorganic nanoparticles introduced to the substrate serve as a linker to which a target-specific substance such as an antibody can be bound, and they also increase the surface area of the substrate, thus increasing a surface area where a target substance to be detected can contact the substrate. In this regard, the bioprobe can be effectively used for detection, dosing, or analysis of various biomolecules or other chemical substances.
摘要:
Provided are a stimuli-sensitive magnetic nanocomposite using a pyrene-conjugated polymer and a method of preparing the same. Particularly, the stimuli-sensitive magnetic nanocomposite includes magnetic nanoparticles, an amphiphilic compound including at least one hydrophobic domain having a material having a pyrene structure and at least one hydrophilic domain and a pharmaceutically active ingredient. Here, the amphiphilic compound surrounds the pharmaceutically active ingredient, and the pharmaceutically active ingredient surrounds the magnetic nanoparticle and is chemically bound to a hydrophobic domain. Accordingly, the magnetic nanoparticles and the pharmaceutically active ingredient are stable in an aqueous solution, have excellent magnetic properties and a rapid drug release behavior due to a specific stimulus, and exhibit targeting according to a tissue-specific binding component. Thus, the stimuli-sensitive magnetic nanocomposite has target specificity and serves as a contrast composition or pharmaceutical composition.
