3D bioprinting and scaffolds

Definition

3D bioprinting is a revolutionary technology that creates living tissue constructs by layering bio-inks containing living cells and biomaterials. Scaffolds, on the other hand, are supportive structures designed to provide a framework for cells to grow and develop into functional tissues, mimicking natural biological environments. This technology not only enhances tissue engineering but also aligns closely with nature's designs, showcasing how innovation can arise from understanding biological principles.
