Introduction: Tissue engineering is a field based on the idea that the majority of human tissues and organs can be replaced by autologous artificial tissues, composed of cells and scaffolds [1]. There are many scaffold fabrication techniques, but one of the most promising ones is laser multiphoton polymerisation [2]. A wide range of materials can be structured via this technique, but hybrid organic-inorganic materials are among the most widely investigated due to their high structuring quality and ease of workflow [3]. Here, we present an aluminium-based hybrid organic-inorganic material that is relatively simple to prepare, tune and structure in 3D. We investigate its biocompatibility by comparing it to a hybrid organic-inorganic material based on zirconium and a commercially available OrmoComp (Micro Resist Technology GmbH).
