Abstract: The present technology relates to encapsulated particles of cannabidiol (CBD) by confined impingement jet (CIJ) mixing or multi-inlet vortex mixing (MIVM). The methods and processes employ intense, turbulent mixing of a solvent stream and an antisolvent stream, to generate self-assembled drug-encapsulating particles stabilized by a polymer. The CBD particles are unexpectedly and advantageously stable in an aqueous environment. They may be subsequently used in the formulation of a variety of products for oral ingestion, including powders for tablets, within creams, or beverage formulations. The resultant products are further highly stable over extended periods of time.

Abstract: The invention described herein relates to colloidal particles useful for photoacoustic imaging. The particles comprise a photoacoustic imaging agent with an absorbance maximum or plateau in the range of wavelengths 700-1100 nm. The imaging agent also displays low optical absorbance at some wavelength in the range 700-1100 nm. This combination of high and low optical absorbance enables background subtraction in photoacoustic imaging applications. The imaging agent is an organic compound having low aqueous solubility so that it is stably encapsulated in the hydrophobic core of the particle. The particle is stabilized by a polymeric surface coating, and the polymeric stabilizing layer on the surface of the particle may contain targeting ligands for targeted diagnostics or therapeutic delivery. The particle core may also contain therapeutic agents or other imaging agents.

Abstract: A method for controlling the encapsulation efficiency and burst release of water soluble molecules from nanoparticle and microparticle formulations produced by the inverted Flash NanoPrecipitation (iFNP) process and subsequent processing steps is presented. The processing steps and materials used can be adjusted to tune the encapsulation efficiency and burst release of the encapsulated water-soluble material. The encapsulation efficiency of the soluble agent in the particles and the burst release of the soluble agent from the particles can be controlled by: (1) the copolymers used in the assembly or coating process, (2) the degree of crosslinking of the nanoparticle core, (3) the incorporation of small molecule or polymeric additives, and/or (4) the processing and release conditions employed.

The constructs, which are controllably sized, are nanoparticles comprising hydrophobic elements, electrostatically charged particles with hydrophobic surfaces, hydrophobic inorganic nanostructures, and amphiphilic copolymers with hydrophobic domains and hydrophilic domains.
