Scientists of the MIPT Cell Signaling Regulation Laboratory have developed a new low cost, reproducible system for the co-cultivation of cells. This system is based on a polymerized BSA membrane. Its size and relief are determined by a mold created using a 3D printer. The possibility of co-cultivation is achieved with magnetic nanoparticles (NPs). This NPs cross-linked into the membrane, which allows it to be kept afloat in a culture liquid using a constant magnetic field. The study was published in the journal Bioprinting.
