A team of researchers from the Moscow Institute of Physics and Technology created a system for cell co-cultivation with the help of a 3D printer, which reduces costs, reported the press service of the Ministry of Investment, Industry, and Science of the Moscow Province.
The system is based on a polymerized bovine serum albumin (BSA) membrane, printed in 3D. The membrane containing magnetic nanoparticles is deposited in the system equipped with magnets. Thanks to the magnetic field, the membrane remains suspended in the fluid, the institution explained in a statement.
Such conditions, he noted, allow the co-cultivation of cells that remain alive and can divide.
The most important challenge was choosing a membrane material that does not influence cells. The researchers opted for BSA, a protein that is widely used in various fields of biology and can be found in any laboratory.
The cost of the 3D printed membrane is around a dollar, a price lower than that of its analogs on the market. Ekaterina Zinovieva, head of the Ministry, stressed that innovation will increase the efficiency of laboratories that study cell structure.
