  • Publication number: 20210270731
    Abstract: The present disclosure provides a terahertz biological detection method and a device comprising the same, in which biological samples with different molecular formulas have their characteristic peaks in the terahertz band. In the process of sweeping frequency with terahertz, when the terahertz frequency point corresponds to the characteristic peak frequency of the substance to be detected, resonant absorption occurs, and the transmitted/reflected terahertz wave electric field intensity will suddenly decrease. In the electromagnetically induced transparency spectrum corresponding to the Rydberg quantum state, the signal splitting amplitude is significantly reduced. Therefore, the characteristic peak frequency and specific content of the substance to be detected can be accurately determined by comparing the dependence of the Rydberg quantum state with the additional terahertz electric field intensity on the excitation energy level.

  • Patent number: 11085022
    Abstract: Disclosed are an inflammation-targeted neutrophil granulocyte drug delivery system and use thereof, wherein the drug delivery system includes neutrophil granulocytes and a therapeutic substance or a detectable substance loaded into the neutrophil granulocytes or onto the surface of the neutrophil granulocytes in a direct or indirect way. By using the neutrophil granulocytes as a carrier of a drug, the drug is actively targeted to an inflammatory site, thereby increasing the drug concentration at the inflammatory site. Under the stimulation of cytokines, the neutrophil granulocytes arriving at the inflammatory site are abnormally activated, disintegrate rapidly, and die in the way of “Neutrophil extracellular traps (NETs)”. This helps to rapidly release the loaded drug to the targeted site, so as to improve the therapeutic effect and reduce the toxic and side effects.
