Two Photon Polymerization Equipment

双光子光刻(TPL)是一种多用途的工艺，它利用飞秒激光脉冲的非线性吸收，在空间和时间上进行高度控制，从而制造出分辨率在亚微米范围内的物体。TPL的高分辨率特性允许创建复杂的结构，利用它们的几何结构来提高性能。这些结构包括组织工程的支撑结构(水凝胶)、芯片器官(人体组织模型)、微流体(化学、生物、医学、物理)、材料技术(多材料结构)、微电子和机械系统(MEMS、BioMEMS)、光子学(晶体、波导)、微透镜和纳米表征工具的原型(AFM TIPS、微针)。这项技术的应用范围和工业适用性是一个吞吐量问题，即在保持亚微米特征的同时，能够产生几立方米甚至厘米的体积。随着第三方物流领域的最新进展，这现在已经成为可能，使具有工业意义的广泛应用成为可能。克服了设置和材料性能方面的限制，使大型(厘米级)和小型(亚微米级)3D结构能够在同一制造周期内在短时间内完成。慕尼黑工业大学最感兴趣的是燃料电池和电解液的生物接口、细胞培养和电极制造方面的应用，而随着设备的可用，还可以进行广泛的其他研究工作。

Two-Photon Lithography (TPL) is a versatile process enabling the fabrication of objects with resolutions in the sub-micrometre range by utilizing nonlinear absorption of femtosecond laser pulses to induce cross-linking with a high spatial and temporal control. The high-resolution nature of TPL allows to create complex structures that leverage their geometry for performance. Such structures include support structures for tissue engineering (hydrogels), organs-on-chips (human tissue models), microfluidics (chemistry, biology, medicine, physics), materials technology (multimaterial structuring), microelectronic and mechanical systems (MEMS, BioMEMS), photonics (crystals, waveguides), microlenses, and prototypes for nano-characterization tools (AFM tips, Microneedles). The range of applications as well as the industrial applicability of this technology is a matter of throughput, i.e. the ability to create volumes of several cubic milimeters or even centimeters while preserving sub-micrometre features. With the recent advances in the field of TPL, this has now become possible enabling a wide range of applications with industrial relevance. Limitations in set-up and material properties have been overcome enabling both large (centimetre scale) and small (sub-micrometre scale) 3D structures in the same fabrication cycle within a short time. The Technical University of Munich is most interested in applications within biointerfaces, cell culture and electrode fabrication for fuel cells and electrolysers, whereas a wide range of other research endeavours can be pursued with the availability of the equipment.
