rise to tailored composite particles.

APT technology formulates blends through the adsorption/adherence of fine "guest" particles on to the surface of coarse "host"particles. The production of these new "functionalised" particles occurs in an environmentally friendly manner whereby the powder undergoes fluidisation/aerosolisation through the injection of a gas "air‐blade", allowing coating of the guest on to host through particle‐particle interaction, as opposed to the solid‐solid blending occurring in current state of the art technologies. The resulting powders display dispersion and coating of all the fine guest materials on to the host particles. The uniqueness of this particular dry coating technique is the use of no solvent in a relatively isothermal process with the absence of particle attrition during formulation. APT is therefore able to formulate not only unstable drugs but address challenges with industry standard blending methods.
