Te LBL-Technology (derived from the term "layer-by-layer") is a high-tech tool for making unique multifunctional nano- and micron-sized capsules which are invisible to the human eye.

For instance, the head of a pin, 1.5 mm across, could contain some three thousand million capsules. Functionally designed and custom-made, these capsules suit a variety of pharmaceutical and non-pharmaceutical purposes which not only allow the development of a variety of advanced drug-delivery products, but can also be applied to other types of products, such as foodstuffs and food ingredients, nutraceuticals, diagnostics, biosensors, enzyme catalysts, paper, and paints. In fact, there may be no other encapsulation technology available which provides such high-end capsules.
