摘要：

Two-photon polymerization (TPP) uses nonlinear light interactions in photo-cross-linkable precursors to create high-resolution (similar to 100 nm) structures and high dimensional fidelity. Using a near-infrared light source in TPP results in less scattering and a higher penetration depth, making it attractive for creating biological models and tissue scaffolds. Due to unmatched flexibility and spatial resolution, they range from microvascular constructs to microneedles and stents. This review reviews the working principles and current inks used for TPP-printed constructs. We discuss the advantages of TPP over conventional additive manufacturing methods for tissue engineering, vascularized models, and other biomedical applications. This review provides a short recipe for selecting inks and photoinitiators for a desired structure.
