Applications and markets

The Problem: Immobilising antibodies

Current state of the art for immobilizing
antibodies on a substrate (basis for IVD tests) is a multi-step, wet chemical process that takes between 24 to 72 hours because of required drying and incubation steps.

Our Solution

We are able to immobilize antibodies on a glass substrate using our proprietary Molecular Plasma process in less than 5
seconds. The samples were tested by the University of Leuven (Belgium) and showed comparable adhesion and biological performance (ELISA) as current standard. We have shown that our process is approx. 5000 times faster and much simpler than current standard. We anticipate similar
performance with other biomolecules such as DNA, RNA and polypeptides.

The Problem: Bonding “TEFLON” liners

Fluorinated plastic films are valued for their resistance and impermeability. However, the integration of the EFEP film into composite structures is very difficult due to its inertness.
Previous methods, such as wet chemical and traditional plasma activation of the surface did not meet the customer’s requirements.

Our Solution

We solved the customer’s problem by grafting adhesion-improvement molecules onto the EFEP film using our proprietary Molecular Plasma Technology. This allowed us to achieve perfect adhesion whilst maintaining the integrity of the EFEP film.

The Problem: Car Mirror assembly

The current method of adhesion for items such as rear-view mirrors onto windscreens consists of manually applying a wet chemical primer  followed by a resin such as polyurethane. The customer wanted to look at automating the process while reducing the toxicity and quantity
of the chemicals used.

Our Solution

We produced a solution that met all technical specifications of its client, a major German luxury car manufacturer. Furthermore, as our solution reduces the use of chemicals by several orders of magnitude and can easily be integrated in their automated manufacturing line, we met all their expectations.
