The Infection Biology and Array Technologies working group also develops virus-based therapies. Virus-like particles (VLP) are bio-based capsules that mimic viruses. The VLP's surface can be equipped with antigens, thus enabling the application of VLPs as a vaccine. Alternatively, VLPs provide a vehicle for targeted "drug delivery".
The production of virus variants by genome engineering methods such as bacterial artifical chromosome (BAC) is another expertise of the working group.
