  • Patent number: 10202432
    Abstract: A dual targeting drug carrier is provided. The dual targeting drug carrier comprises a first targeting molecule and a second targeting molecule, wherein the targeting molecule comprises peptide, protein or antibody. The targeting molecule can bind to specific receptors, proteins, or glycoproteins to recognize the specific tumor cells, tissues, or organs. The dual targeting drug carriers are further conjugated with imaging agents, radioactive molecules (radiopharmaceuticals, isotopes, or chemotherapeutic drugs) or nanoparticles to form a conjugate.

  • Patent number: 8613850
    Abstract: A system for electrochemical quantitative analysis is provided. The system includes a measuring apparatus having a plurality of analysis modes. Each of the analysis modes is for quantitatively analyzing different biochemical substance. The system further includes a plurality of test strips. Each of the test strips has a different identification component for a different analysis mode. When one of the plurality of test strips is selected to electronically connect to the measuring apparatus, the measuring apparatus executes one of the plurality of analysis modes according to the identification component of the selected test strip to quantitatively analyze a corresponding biochemical substance.
