Examples of where SEM-EDS is actively contributing to research into the preparation and effectiveness of different additives include:
Polymers are used as bio-degradable implanted hosts for the delivery of drugs. However the distribution of the active biomacromolecule (drug) is critical as aggregation reduces the activity and reliability of delivery as the implanted polymer breaks down. SEM-EDS directly shows the distribution of additives by analysing unique constituent elements. This provides an important tool for studies of different stabilisation additives and preparation methods for polymer implants

Similarly the distribution of green alternatives to traditional flame retardants can be imaged directly by SEM-EDS, providing important evidence to support direct testing of the effectiveness of alternative additives.
