摘要:
A hybrid laser printing (HLP) technology that utilizes ultrafast laser in sequential additive-subtractive modes to create 3D hydrogel constructs. The approach involves the synergistic use of additive crosslinking and subtractive ablation processes that are conventionally mutually exclusive. HLP can be operated at virtually any penetration depth and allow fabrication of multi-layer hydrogel constructs at micrometer resolution. HLP was used to print ready-to-use functional chips using commonly used hydrogels for potential cellular communication and migration applications. HLP was also found to be compatible with in situ printing of cell-laden hydrogel constructs. HLP makes shaping of soft hydrogels into 3D multiscale functional devices possible.
