  • Patent number: 11707527
    Abstract: A nanoscale drug carrier capable of crossing the blood-brain barrier. Said carrier can target brain lesions (brain tumors or other neurodegenerative diseases). The targeting drug carrier capable of crossing the blood-brain barrier comprises all-heavy-chain human ferritin or a functional fragments reconstituted structure or a mutant thereof. The manner for crossing the blood-brain barrier of the drug carrier is receptor-mediated transcytosis. The drug carrier provides an effective nanoscale drug carrier for the treatment of brain tumors or other neurodegenerative diseases.

  • Patent number: 10195155
    Abstract: The present disclosure relates to a tumor-targeted drug delivery system, comprising a tumor-targeted drug carrier and a tumor-treating drug, wherein the tumor-targeted drug carrier comprises full heavy-chain human ferritin. The present disclosure also relates to a method for preparing the tumor-targeted drug delivery system comprising: depolymerizing a polymerized full heavy-chain human ferritin; adding a tumor-treating drug to the depolymerized full heavy-chain human ferritin so as to bind the tumor-treating drug to the depolymerized full heavy-chain human ferritin; and re-polymerizing the depolymerized full heavy-chain human ferritin bound with the tumor-treating drug to form a nanoparticle.

  • Publication number: 20160334397
    Abstract: This invention provides a nanozyme immunochromatographic detection method for detecting a substance to be tested in a liquid sample, comprising, in this order, the steps of: 1) providing a detection probe, which is prepared by coupling a magnetic nanoparticle to a first molecule capable of specifically binding to the substance to be tested; 2) providing a capture probe, which is an immobilized second molecule capable of specifically binding to the substance to be tested; 3) bringing the liquid sample into contact with the detection probe; 4) bringing the liquid sample, which has been in contact with the detection probe, into contact with the capture probe; and 5) adding a hydrogen-donor substrate and a peroxide to the capture probe subject to the step 4) so as to perform color development reaction. This invention further provides a nanozyme immunochromatographic detection apparatus for detecting a substance to be tested in a liquid sample.

  • Publication number: 20160166472
    Abstract: An air-cooling micro drop pill capsule production line comprises a drop pill system, an air-cooling circulation system and a control system. The drop pill system comprises a molten material tank and a dripper. A vibration apparatus is arranged between the molten material tank and the dripper, and drives the dripper to vibrate up and down. A vibration shear force cuts liquor flowing out from the dripper into drops, and drop pills are formed after the drops fall into the air-cooling circulation system and are cooled. An online monitoring apparatus is arranged on the dripper, and comprises a pulse signal emission mechanism with an emission frequency which is the same as a vibration frequency of the vibration apparatus. The control system controls and regulates a dropping parameter according to a monitoring result of the online monitoring apparatus.

  • Publication number: 20150037817
    Abstract: The invention relates to a bifunctional tumor diagnostic reagent and a method for tumor diagnosis. The reagent consists of a protein shell specifically recognizing a cancer tissue and/or a cancer cell and an inorganic nano-core having the catalytic activity of a peroxidase. The bifunctional tumor diagnostic reagent has two functions, i.e., tumor specific identification and color development, and enables the tumor specific identification and the color development to be completed in one step, and the operation of the process is simple and convenient.
