Alvéole, represented by Sygnis in Poland, presents PRIMO which gives researchers the versatility to create in vitro cell microenvironments for more reliable and reproducible 2D & 3D cell models. PRIMO is used worldwide to functionalize cell culture substrates or microfluidic chips and to structurate UV sensitive materials such as SU8 or photosensitive hydrogels to design customized organ-on-chip or spheroid wells.
