Diatoms as building blocks for new materials

Why?

Diatoms are silica micro-sized exoskeletons which have various nano/micro porous architectures that can be used as sustainable and cost-effective carriers for the controlled release of active substances.

How?

The exoskeletons’ ability to store and subsequently release substances can be used in for instance self-healing anti-corrosion coatings, building materials, the food industry, and controlled internal drug delivery.

When?

The next step in this research is to explore how the species-dependent diatom architecture influences the release kinetics, and how the architecture and surface of the exoskeletons can be adjusted to influence these release kinetics.
