“…The group repeated the same strategy for polylactide‐carbon black FDM prints, and reported faradaic peak separation values superior to that reported by any FDM printed polylactide‐based electrode thus far. [ 251 ] A separate group investigated the electroplating of both Cu and Ni onto FDM electrodes, for the detection of glucose. [ 252 ] SEM images revealed electroplating to form good coverage of both Cu and Ni on the electrode's surface, with average particle size of 2.31 and 1.4 µm, respectively.…”

With the impending Industrial Revolution 4.0, the information produced by sensors will be central in many applications. This includes the healthcare sector, where affordable healthcare and precision medicine are highly sought after. Electrochemical sensors have the potential to produce affordable, high sensitivity and specificity, intuitive, and rapid point‐of‐care diagnostics. Underpinning these achievements is the choice of material and the fabrication thereof. In this review, the different types of materials used in electrochemical biosensors are reported, with a focus on synthetic conductive materials. The review demonstrates that there is an abundance of materials to select from, and compositing different types of materials further widens their applicability in biosensors. In addition, the fabrication of such materials using the state‐of‐the‐art of fabrication technology, additive manufacturing (AM), is also detailed. The need for compositing is evident in AM, as the feedstock for certain AM technologies is inherently nonconductive. Both material choice and fabrication technologies limitations are also discussed to highlight opportunities for growth. The review highlights how recent technological advancements have the potential to drive the healthcare industry toward achieving its primary goals.

“…The developed MOF-based 3D-printed device presents distinct and significant advantages over existing MOF-based electrodes used for the ASV of Pb(II) [13][14][15][16][17]. The use of 3D-printing technology for the preparation of the device offers plenty of smart features including desktop-sized equipment, very low costs, production speed, strict control of the printing parameters, and ease of printing operation, while it generates negligible non-toxic waste [20][21][22][23][24][25][26][27][28][29][30][31][32]. The adopted process of mixing a small quantity of MOF with GP to produce the WE is by far simpler than drop-casting leading to stand-alone sensors, as the surface of the WE is renewed via a slight pressure on the syringe plunger.…”

In this work, a voltammetric method based on a metal organic framework (Ca-MOF)-modified carbon paste electrode for lead determination was developed. The MOF-based electrode was packed in a new type of 3D-printed syringe-type integrated device, which was entirely fabricated by a dual extruder 3D printer. After optimization of the operational parameters, a limit of detection of 0.26 µg L−1 Pb(II) was achieved, which is lower than that of existing MOF-based lead sensors. The device was used for Pb(II) determination in fish feed and bottled water samples with high accuracy and reliability. The proposed sensor is suitable for on-site analyses and provides a low-cost integrated transducer for the ultrasensitive routine detection of lead in practical applications.

“…Polylactic acid as such cannot be found in nature but needs to be industrially prepared with lactic acid polymerization. However, at the time, the instability of the material was not appreciated as a positive feature, and it was not until the 1960s that the utility of polylactide to biomedicine was realized and reported (Vaněčková et al 2020). Poly (lactic acid) (PLA) is a biodegradable polymer that has a variety of applications.…”

Driven by the increasing interest in nanotechnology, materials that spontaneously form ordered nanostructures are becoming an important area of investigation. The development of new polymer-based biomaterials relies on knowledge of the underlying relations between the properties and the structure of these materials at multiple length scales. On the basis of sources, biomaterial polymer films are categorized into two different classes. In the first class, polymers are made from protein, natural rubber, cellulose, etc. these are also called natural polymers. The second category is largest one; it carries the artificial polymer or synthesized polymer, where natural polymers are chemically treated or synthesized in lab. Among these, chitosan is widely used linear polysaccharide biopolymer derived from chitin by deacetylation, chitosan has numerous advantages as a biomaterial; Chitosan is a unique biopolymer in the respect that it is abundant, cationic, lowtoxic, non-immunogenic, biodegradable, and due to its positive charges at
