Recent Advances in Organ‐on‐Chips Integrated with Bioprinting Technologies for Drug Screening

Currently, the demand for more reliable drug screening devices has made scientists and researchers develop novel potential approaches to offer an alternative to animal studies. Organ‐on‐chips are newly emerged platforms for drug screening and disease metabolism investigation. These microfluidic devices attempt to recapitulate the physiological and biological properties of different organs and tissues using human‐derived cells. Recently, the synergistic combination of additive manufacturing and microfluidics has shown a promising impact on improving a wide array of biological models. In this review, different methods are classified using bioprinting to achieve the relevant biomimetic models in organ‐on‐chips, boosting the efficiency of these devices to produce more reliable data for drug investigations. In addition to the tissue models, the influence of additive manufacturing on microfluidic chip fabrication is discussed, and their biomedical applications are reviewed. Demands for reliable drug screening and alternatives to animal studies, organ‐on‐a‐chips, are attracting researchers’ attention as one of the most promising biomedical tools for this mean. This manuscript contains a summary of different bioprinting techniques to facilitate the construction of more complex and relevant biological models, enhancing automation and reproducibility and making the process high throughput.
