“…In recent years, 3D bioprinting technologies have made great progress in replicating the delicate architecture of different tissues and mimicking the realistic in vivo microenvironment due to its ability to deposit supporting biomaterials and living cells at the same time in a cell-friendly manner [ [13] , [14] , [15] ]. In addition, 3D-bioprinting is an ideal tool applied in organ modelling, multifunctional tissue repairing, and the production of biological sensors [ [16] , [17] , [18] , [19] , [20] , [21] ].…”
