Entering a new era of 3D printing for DNAs and proteins

Three-dimensional (3D) bioprinting is a useful technique that has been widely utilized in our lives, ranging from reconstructive plastic surgery to artificial organ production. However, many biopolymers, such as nucleic acids, polysaccharides, and proteins, cannot be readily constructed into a desired 3D shape at the submicron- or nanoscale due to their inherent rheological and structural properties. Can we truly achieve the free-form and high-resolution structuring of various biomolecules using 3D printing technology?
