  • Publication number: 20240117205
    Abstract: A method of making a silver-silicalite coating on a surface of a stainless-steel substrate is provided. The method includes mixing metakaolin with an aqueous solution of NaOH to form a first mixture. The method further includes mixing silica gel and silver nitrate with the first mixture to form a second mixture. Furthermore, the method includes mixing Zeolites Socony Mobil-5 (ZSM-5) with the second mixture to form a third mixture. The method further includes hydrothermally treating the stainless-steel substrate with the third mixture to form the silver-silicalite coating on the surface of the stainless-steel substrate. The hydrothermal treatment is carried out in the absence of an organic template. The stainless-steel substrate coated with the silver-silicalite coating, prepared by the method of the present disclosure, has lower corrosion in comparison to the same stainless-steel substrate without the silver-silicalite coating.

  • Publication number: 20240100197
    Abstract: Silica nanocarriers hybridized with superparamagnetic iron oxide nanoparticles (“SPIONs”) and curcumin through equilibrium or enforced adsorption technique. Methods for dual delivery of SPIONs and curcumin to a target for diagnosis or therapy, for example, for SPION-based magnetic resonance imaging or for targeted delivery of curcumin to a cell or tissue. The technique can be extend to co-precipitation of mixed metal oxide involving Ni, Mn, Co and Cu oxide. The calcination temperature can be varied from 500-900° C. The nanocombination is functionalized with chitosan, polyacrylic acid, PLGA or another agent to increase its biocompatibility in vivo.

  • Publication number: 20240100182
    Abstract: A nanomedicinal composition comprising a nanocarrier and a pharmaceutical agent mixture comprising an anti-cancer therapeutic and an antioxidant. The nanocarrier comprises a porous silicate matrix and particles of a magnetic ferrite disposed in the pores of the porous silicate matrix. The pharmaceutical agent mixture is disposed in the pores and/or on the surface of the nanocarrier by a solution phase impregnation process. The nanomedicinal composition is used in a method of treating breast cancer.

  • Publication number: 20240082422
    Abstract: A method of delivering insulin, including: orally administering to a subject a composition containing a ferrisilicate material, polyethylene glycol, and insulin. The insulin at least partially penetrates pores of the ferrisilicate material to form a ferrisilicate insulin composite and the polyethylene glycol, at least partially enfolds the ferrisilicate insulin composite to form the composition. The composition has an insulin release rate of 10-50% after 100-500 hours following oral administration.
