Polymer Nanoparticles

Ideal Technology for Producing Polymer Nanoparticles.

Polymer nanoparticles represent one of the most innovative drug delivery systems due to their ability to deliver a wide variety of drugs and improve efficacy. Initially formulated like emulsions, a very small droplet consisting of a solvent containing both the polymer and drug of choice is formed. Once the solvent is evaporated, the polymer hardens and encapsulates the drug leaving very small, solid particles.

Key steps in the formulation of Polymer Nanoparticles:

Key Formulation stages

  • Aqueous phase: water + surfactant are combined
  • Oil phase:  the polymeric and other hydrophobic ingredients (such as actives, contrast agents, etc.) are dissolved in the water immiscible solvent.

Factors to be considered in selecting the solvent:

  • Water miscibility
  • Boiling point
  • Toxicity
  • Active Pharmaceutical Ingredients (APIs)
  • Diagnostic ingredients (such as contrast enhancers)
  • Other ingredients (such as para-magnetic particles, metal oxides, etc.)

Key steps in the manufacture and extraction process:

Processing steps

  • Prepare the separate oil & aqueous phases

  • Add oil to the water phase

  • Mix using a rotor-stator motor to create a coarse emulsion as a stable pre-mix

  • Process the pre-mix using a Microfluidizer® high shear homogenizer - in selecting the model, consider the critical processing parameters of chamber type, processing pressure, temperature and number of passes

Solvent Extraction process:

  • Allow the solvent to evaporate in a hood while mixing

OR

  • Use a solvent-exchange technique, such as a separator funnel or rotary-evaporator
