Analysis of pharmaceutical nanoparticles can deliver a wealth of information to assist product development particularly for complex drug delivery technologies, formulation or product characterisation

Pharmaceutical nanoparticles are being developed for a range of healthcare product applications including drug delivery, controlled release systems and medical devices. Lipid-based or polymeric and inorganic nanoparticles can be tailored to enable drug delivery for highly complex therapeutic products including mRNA, oligonucleotides, gene therapies and other biologic drugs. These products present multiple challenges for product characterisation that require sophisticated analytical techniques operated by experienced analysts in order to drive robust data and the insight you need to support your drug development activities. 

Covering both physical and chemical analysis expertise, our nanoparticle experts provide comprehensive R&D or Good Manufacturing Practice (cGMP) compliant analytical capabilities for nano-sized systems for both particles or suspensions. We have supported clients across a range of applications including nanoencapsulation of active ingredients (APIs), lipid nanoparticles (LNPs) for drug delivery or dispersed metallic nanoparticulate systems applied to diagnostics applications. Bringing quality and safety to life, we offer Total Quality Assurance expertise to help you to meet and exceed quality, safety and regulatory standards.
