    Abstract: A recombinant fluorescent protein nanoparticle having high fluorescence intensity and a method of detecting a target material using the same are provided. The protein nanoparticle has higher fluorescence intensity than a fluorescent protein, and is resistant to denaturation of the fluorescent protein at room temperature, thereby having higher structural stability than the fluorescent protein itself. In addition, since a self-assembled protein is used as a fusion partner of the fluorescent protein, the protein nanoparticle is biocompatible and safe. Moreover, when a linker peptide is additionally inserted into the protein nanoparticle, a suitable distance between the self-assembled protein and the fluorescent protein is maintained, thereby considerably increasing fluorescence intensity of the protein nanoparticle. The probe-binding protein nanoparticle can control distances between the fluorescent proteins on the surface thereof, thereby maximizing fluorescence intensity.

  • Publication number: 20120294945
    Abstract: The present invention relates to a drug delivery composition comprising a hyaluronic acid-peptide conjugate micelle and a production method thereof. According to the drug delivery composition and the production method of the drug-loaded, hyaluronic acid-peptide conjugate micelle of the present invention, the reaction for encapsulating can proceed in a mixed solvent of an aqueous solvent and an organic solvent. Therefore, the present invention can be applied to various types of water-insoluble active components and the biocompatible and biodegradable derivative can encapsulate a drug to provide a drug-loaded micelle, which is safe to be applied for human bodies. Moreover, the micelle has a therapeutic effect from the peptide contained therein, which can act in combination with the drug as packing therein. Therefore, the drug delivery composition and its production method can be utilized in the field of producing a sustained release formulation with an extended duration of the medicinal effect.

  • Publication number: 20120244357
    Abstract: A process for producing cellulose nanocrystals (CNCs) involves providing a cellulosic material, contacting the cellulosic material with an inorganic persulfate at an elevated temperature to produce CNCs, and recovering the CNCs. The process permits one-step production of CNCs from vegetative biomasses such as flax and hemp. Cellulose nanocrystals produced by the process with carboxylic groups are more uniform and have higher aspect ratios than CNCs produced by prior art processes.
