Cover Story: The rapid fabrication of complex, biocompatible, and bioactive hydrogel constructs that can mimic the in-vivo extracellular microenvironment has been explored using several techniques. State-of-the-art technologies, such as 3D extrusion bioprinting, and state-of-the-industry technologies, such as lithographic microfabrication, show promise for their use in the fabrication of biosensors, tissue engineering constructs, and regenerative engineering. These methods, used in tandem, may allow for the incorporation of proteins, peptides, enzymes, cells, and conductive nanomaterials to allow for an engineered approach to a wide variety of bioengineering problems. Most notably, a combination of these two fabrication techniques (or others) may be used in the fabrication of complex, hybrid hydrogel structures. View Paper here.
