“…Microcarriers are generally described as microparticles made from natural or synthetic materials with sizes ranging from 1 μm to 1000 μm, that are widely used in drug/cell delivery, regenerative medicine, and TE [ 33 , 34 ]. Moreover, microcarriers have been applied as microspherical scaffolds in biological and biomedical applications such as cell culture, expansion, delivery, modeling for biological studies, biosensor, and medical implants [ [35] , [36] , [37] , [38] ]. To date, a variety of biomaterials have been developed to fabricate microcarriers using various techniques and methods, such as bioactive inorganic materials, natural/synthetic polymers, and their composites [ [39] , [40] , [41] ].…”
