    The purpose of this study is to demonstrate the ability of additive manufacturing, also known as 3D printing, to produce effective drug delivery devices and implants that are both identifiable, as well as traceable. Drug delivery devices can potentially be used for drug release in the direct vicinity of target tissues or the selected medication route in a patient-specific manner as required. The identification and traceability of additively manufactured implants can be administered through radiofrequency identification systems. The focus of this study is to explore how embedded medication and sensors can be added in different additive manufacturing processes. The concept is extended to biomaterials with the help of the literature. As a result of this study, a patient-specific drug delivery device can be custom-designed and additively manufactured in the form of an implant that can identify, trace, and dispense a drug to the vicinity of a selected target tissue as a patient-specific function of time for bodily treatment and restoration.

    Nanotechnology holds the promise of bringing revolutionary therapeutic strategies into the clinic. However, an enormous fraction of the currently proposed nanotechnology-based therapies suffers from lack of reproducibility, complexity, high costs, and scale-up-related issues. For these reasons, the research community is moving toward the miniaturization of biomaterials and fabrication methods. Customizable microfluidic-based products have gained tremendous relevance in the development of biomedical technologies. This review provides an overview of different materials that can be used for the fabrication of microfluidic devices, as well as the other parameters influencing the production of biomaterials and biosensors. Moreover, several advanced microfluidic-based technologies that are designed to overcome the current challenges of cancer, immunotherapy, and diabetes therapy, among others are described. Then, the pros and cons of microfluidics as alternative to conventional preparation methods, and the challenges of translating this technique to an industrial context are highlighted. Overall, microfluidic technologies and their accessibility to the research community offer a set of exciting opportunities to bridge the development of innovative therapies and their commercialization in the foreseeable future.
