Different measurement methods for different particle sizes

With the increasing proportion of biomolecules in the drug development pathways of many pharmaceutical companies, people are more and more concerned about solving related problems in development, production and regulation. Since the potential immunogenicity of drugs is an element of great concern to manufacturers and regulators, how to define the purity and efficacy of biological drugs is much more complicated than those of small molecule drugs. This in turn highlights the industry's urgent need for high-quality analytical tools-hoping that they can help to fully characterize biopharmaceutical particles and aggregates, and at the same time pay more and more attention to the characterization of the physical and chemical characteristics of drug particles and contaminants.
