Spray Drying and Particle Engineering

Bioavailability Enhancement

Serán has decades of experience in particle engineering, including spray drying. Our deep scientific expertise, formulation and dosage form experience, and technical knowledge form the bedrock of our particle engineering leadership. Our technology enables delivery of drugs to a wide variety of biological targets, including the small intestine to enhance bioavailability, colonic, and pulmonary delivery.

Spray Drying and Particle Engineering

Enhancing Solubility, Bioavailability, and Therapeutic Performance

Serán has extensive spray drying capabilities. Our team has decades of experience developing spray drying processes, related formulations, and analytical methods and techniques. We have leveraged our core knowledge of particle engineering and formulation requirements to design and build optimum spray drying systems for pharmaceutical applications. At present, Serán has 6 separate spray drying systems that can produce material for a wide variety of drug delivery requirements.


Particles with controllable size and structure are highly desired for their physical properties (e.g., for manufacturing ease) or because they exhibit enabling performance (e.g., improved pharmacokinetics). Serán has extensive expertise in designing and manufacturing of particles ranging from a few tens of nanometers to several hundred microns in size. Particle architectures can be either homogeneous or structured on micron or nanometer length scales, as needed to enhance product performance.

Serán takes a holistic approach to process and product design to enable pre-clinical studies with minimal quantities of API while simultaneously developing knowledge to facilitate rapid scale-up as the program progresses through clinical trials toward commercialization. This goal is achieved through a combination of fundamental process modeling, material-sparing benchtop techniques, and custom-designed manufacturing equipment that preserves the essential process elements across scales and connects them to the models and bench experiments. The end result is a data-driven, risk-based collaboration tailored to meet client's needs.
