Area of Science:

  • Materials Science
  • Nanotechnology
  • Biomedical Engineering

Background:

  • Layered double hydroxides (LDH) are inorganic materials with potential applications in drug and gene delivery.
  • Controlling the size and morphology of LDH is crucial for effective delivery systems.

Purpose of the Study:

  • To synthesize uniform, small-sized layered double hydroxides (LDH) using wet chemistry.
  • To investigate the potential of LDH as an injectable drug delivery carrier.

Main Methods:

  • Layered double hydroxides (LDH) were prepared via wet chemistry with aging times of 1 and 3 days.
  • Transmission electron microscopy (TEM) and selected area diffraction (SAD) were used to characterize particle size, shape, and crystallinity.
  • In vivo testing was performed on Sprague Dawley rats to assess LDH as an injectable vehicle.

Main Results:

  • Uniform, small-sized (100-200 nm) LDH particles with a hexagonal, thin, plate-like shape were successfully synthesized.
  • Electron microscopy confirmed that the LDH particles were single crystals.
  • Initial in vivo testing in rats indicated the potential of LDH as an injectable drug delivery system.

Conclusions:

  • The study successfully synthesized nano-sized LDH particles suitable for drug delivery applications.
  • LDH nanoparticles demonstrate promise as injectable carriers for pharmaceutical formulations.
  • Further research is warranted to fully explore LDH's therapeutic potential.
