Graphene oxide can be referred to as oxidized graphene. Similar to graphene, oxidized graphene possesses remarkable structural features, advantageous properties, and technical applications. Among polymeric matrices, conducting polymers have been categorized for p conjugated backbone and semiconducting features. In this context, doping, or nano-additive inclusion, has been found to enhance the electrical conduction features of conjugated polymers. Like other carbon nanostructures (fullerene, carbon nanotube, etc.), graphene has been used to reinforce the conjugated matrices. Graphene can be further modified into several derived forms, including graphene oxide, reduced graphene oxide, and functionalized graphene. Among these, graphene oxide has been identified as an important graphene derivative and nanofiller for conducting matrices. This overview covers essential aspects and progressions in the sector of conjugated polymers and graphene oxide derived nanomaterials. Since the importance of graphene oxide derived nanocomposites, this overview has been developed aiming at conductive polymer/graphene oxide nanocomposites. The novelty of this article relies on the originality and design of the outline, the review framework, and recent literature gathering compared with previous literature reviews. To the best of our knowledge, such an all-inclusive overview of conducting polymer/graphene oxide focusing on fundamentals and essential technical developments has not been seen in the literature before. Due to advantageous structural, morphological, conducting, and other specific properties, conductive polymer/graphene oxide nanomaterials have been applied for a range of technical applications such as supercapacitors, photovoltaics, corrosion resistance, etc. Future research on these high-performance nanocomposites may overcome the design and performance-related challenges facing industrial utilization.

Persistent disparities exist in access to state‐of‐the‐art healthcare disproportionately affecting underserved and vulnerable populations. Advances in wearable sensors enabled by additive manufacturing (AM) offer new opportunities to address such disparities and enhance equitable access advanced diagnostic technologies. Additive manufacturing provides a pathway to rapidly prototype bespoke, multifunctional wearable sensors thereby circumventing existing barriers to innovation for resource‐limited settings imposed by the need for specialized facilities, technical expertise, and capital‐intensive processes. This review examines recent progress in the additive manufacture of wearable platforms for physiological health monitoring. Supported by an initial overview of relevant techniques, representative examples of 3D printed wearable sensors highlight the potential for measuring clinically‐relevant biophysical and biochemical signals of interest. The review concludes with a discussion of the promise and utility of additive manufacturing for wearable sensors, emphasizing opportunities for expanding access to vital healthcare technology and addressing critical health disparities.

As layer upon layer manufacturing approaches continue to advance the development of tissue engineering and regenerative medicine scaffolds, more products that leverage additive manufacturing methods such as 3D printing and electrospinning have been commercialized for the marketplace. This is especially true for additive manufacturing. Modifications to process parameters allow optimization of mechanical properties. This expands the applicability of currently available bioresorbable materials for tissue engineering advances. This review aims to identify these areas for potential research that would advance the field, specifically focusing on the additive manufacturing of tissue scaffolds with bioresorbable materials. To date, the terms “tissue engineering” and “additive manufacturing” have accelerated in use within research publications, and the clarity of what is required has also increased. Current reports encourage imminent successes in the field of tissue engineering with new potential for biomimicry, improved patient outcomes, and established paths for regulatory compliance. Nonetheless, there are still several challenges to overcome. As outlined in this review, a successful tissue scaffold must address and optimize six (6) critical aspects of the design and performance: biocompatibility, mechanical properties, material resorption, porosity, manufacturing, and biochemical modification. Each vital perspective of a tissue scaffold was thoroughly represented in literature. However, the totality of these aspects must be considered at the onset of a novel design poised to transition the field into an advanced future due to the interconnectivity of each criterion with each other. This is especially true when providing a new device to the clinic considering the design control focus of regulatory statutes. Bioresorbable, aliphatic polyesters hold great potential to aid this progress and mitigate a portion of the trials faced. They are proven compatible with current additive manufacturing processes and boast decades of biocompatibility established through clinical use. The development process, prioritization of processing parameters, and successful navigation through regulations have been observed with products such as Osteoplug®, Restrata®, and Biowick®. These devices exemplified the critical nature of the six aspects, and most especially the first five of them. They were specifically designed to provide environments that support bio-integration at the point of use. The native tissue provides the necessary biologics to off-the-shelf scaffold structures for successful, vascularized tissue regeneration, and ultimately, patient outcomes have been improved. This review focuses on the six critical scaffold characteristics when designing tissue scaffolds with resorbable medical-grade polymers, layer-by-layer fabrication methods, and the commercialization path for the resulting medical products.
