Nvigorea AB

Nvigorea AB is a Swedish Biotechnology company based in Uppsala, creating the mille-feuille filter, which is the world’s first filter paper capable of removing all types of viruses, including the smallest and most resistant ones, from water or protein solutions as easily as brewing coffee.

The virus removal filter paper is composed of 100% cellulose nanofibers and is produced by hot-pressing technology. The virus removal filter paper has been validated for a number of industrial protein samples including plasma-derived and recombinant biologics. The mille-feuille filter paper shows excellent performance and unparalleled cost-efficiency. Its use is envisaged in both downstream and upstream bioprocessing.
