Powders for Inhalation
Expert material science and particle engineering for spray-dried powders for inhalation
Spray drying enables precise control over particle attributes—size, shape, density, and surface morphology—making it a powerful tool for pulmonary drug delivery.

What We Do
At Bend Bioscience, we apply advanced particle engineering principles to develop spray dried powders that meet the performance criteria required for dry powder inhalers (DPIs).
From early feasibility studies through clinical supply, our team in Oregon has the scientific expertise and integrated capabilities to develop optimized inhalation formulations tailored to your molecule and target product profile. We combine deep knowledge of respiratory delivery with state-of-the-art spray drying technologies to produce respirable powders with consistent aerodynamic performance, high fine particle fraction, and excellent dispersibility.
What We Offer
When inhalation is the preferred route, success starts with the right particle. At Bend Bioscience, we bring the science, tools, and experience to engineer those particles for performance, stability, and patient impact.
We offer:
- Feasibility assessment and formulation screening for dry powder inhalation
- Particle engineering strategies to optimize deposition, dose uniformity, and stability
- Development of spray drying processes to achieve target particle size distribution and solid-state attributes
- Inhalation-specific analytical testing, including aerodynamic particle size distribution (APSD) via Next-Generation Impactor (NGI) or laser diffraction
- Full solid characterization analytical testing capability
- Selection and compatibility assessment of DPI devices and packaging
- Integrated formulation and process development to support toxicology, PK, and clinical studies
