**3. Summary and conclusion**

Magnetic levitation-based technologies are new-generation systems that are used in biosensing, diagnostics, as well as tissue engineering. Density-dependent separation of particles provides high-speed analysis of biomolecules, even cells, with low cost in diagnostics. On the other hand, contactless manipulation of cells via magnetic force can also be provided by magnetic levitation systems. In such systems, cells are easily manipulated in the presence of magnetic field after they are magnetized with specialized molecules, such as ferrofluids and paramagnetic agents. By positioning the cells at a specific height in medium, where they can easily interact with each other, natural 3D microenvironment can be formed.

While the magnetic levitation-based systems provide faster, cost-effective, and easy-to-use diagnostic applications, at the same time, it is also used to form 3D cellular structures in tissue engineering field.
