Abstract
Femtosecond Laser Direct Write (fs-LDW) is a promising technique for fine 3D printing of biomaterials such as protein due to nonlinear multiphoton absorption processes facilitating microfabrication along a designated laser light path. Proteinaceous microstructures fabricated by fs-LDW are reported to retain their native protein function. Combined with submicron feature sizes, they might offer diverse biomedical or biochip applications. Here, we show that some amino acids are beneficial to the fabrication process. From our investigation of eight commercially available homopeptides, we found new insights into the fabrication mechanism. The beneficial amino acids could be useful to enhance future 3D printing processes.
