However, it could soon become reality. Scientists have developed a handheld bioprinter that brings modern medicine one step closer to printing functional tissues and organs directly within the human body.

This portable device overcomes the limitations of previous designs, allowing for the printing of multiple materials and precise control over the properties of the printed tissues. With its potential applications in regenerative medicine, drug development, and custom orthotics and prosthetics, this innovation is set to revolutionize healthcare.

Regenerative medicine has made remarkable strides in improving patients' lives by repairing or regenerating damaged tissues and organs. On-site bioprinting, an extension of 3D printing technology, takes this advancement even further by enabling the synthesis of tissues and organs right inside the body. This approach offers hope for addressing challenges such as the scarcity of organ donors and the risks associated with transplantation.
