  • Patent number: 11833486
    Abstract: This application discloses the approach of synthesizing cellulose acetate nanoparticles and rods which may have a chemically functionalized surface and an encapsulated cargo load. Functionalization and/or loading of the cargo are made through a physical mixing of the functionalizing and/or cargo components in the synthesizing bath. This can result in particles with functionalized surfaces with various functional groups, as well as active cargo load encapsulated in the particles. The encapsulated cargo includes but is not limited to biologically, chemically, and optically active substances.

  • Patent number: 11819591
    Abstract: An iron-based alloy absorbable and implantable medical device for internal fixation. A substrate includes an iron-based alloy and degradable polymer. The mass ratio of the iron-based alloy to the degradable polymer is between 1:4 and 4:1. The weight-average molecular weight of the degradable polymer is between 150000 to 3000000, and the polydispersity index thereof is between 1 and 6. The device further includes antioxidants. The iron-based alloy is used as a load-bearing framework or reinforcement phase of the device. By adjusting the mass ratio of the iron-based alloy to the degradable polymer and the combination mode thereof, the corrosion rate of the iron-based alloy in the late period of the implantation is accelerated, and the quantity of corrosion products poorly soluble in the iron-based alloy is reduced. Adding antioxidants to the device further reduces the quantity of the corrosion products poorly soluble in the iron-based alloy.

  • Patent number: 11786525
    Abstract: A high-efficiency anti-tumor nano-drug delivery system containing hydralazine (hydralazine-nanoparticles abbreviated as H-NPs) is provided. The drug delivery system takes hydralazine and doxorubicin combined by a ?-? bond as a hydrophobic core and takes dextran as a hydrophilic shell. The high-effective anti-tumor nano-drug delivery system containing hydralazine can increase the vascular permeability and blood perfusion of the tumor site, improve the enrichment and penetration of nanoparticles in the tumor, reduce tumor hypoxia, increase the sensitivity of the tumor to a chemotherapy drug doxorubicin, and significantly improve its anti-tumor effect by expanding the tumor blood vessels and regulating tumor microenvironment (TME).

  • Patent number: 11771805
    Abstract: An injectable in situ pore-forming hydrogel system and its preparation method and use are provided. The injectable in situ pore-forming hydrogel system uses an injectable hydrogel as a continuous base phase, and isolated live cells and magnesium particles are distributed in the continuous base phase, where the injectable hydrogel is a precursor or prepolymer of hydrogel, which can form hydrogel by cross-linking. The injectable in situ pore-forming hydrogel system can be used to create pores while the gel encapsulates live cells, which makes use of both the injectability and porous structures of hydrogel, which is important for the repair of cavitary, surgically difficult and irregularly defective tissues; meanwhile, magnesium particles generate magnesium ions after the former undergoes gas production and degradation, which can improve the bioactivity of the gel and aid in tissue repair.
