“…The resolution is much higher than the FFF 3D-printed devices, however, longer time of fabrication, the need for post-treatment and curation, and the use of toxic resins are some drawbacks that make SLA less popular than FFF. Nevertheless, one of the first works on the Bismuth film electrodeposition 3D-printed wearable device containing the electrochemical device was fixed at the body using an elastic tape for zinc determination in sweat Dias et al (2019) Images reproduced with permission from American Chemical Society (Snowden et al, 2010;Richter et al, 2019;Sempionatto et al, 2017;Katseli et al, 2021;Dias et al, 2019), Italian Association of Chemical Engineering (Ponce de Leon et al, 2014), Elsevier (Dias et al, 2016;Cardoso et al, 2018;Mendonça et al, 2019;Cardoso et al, 2019;Silva et al, 2020;Escobar et al, 2020;Sibug-Torres et al, 2021;Cardoso et al, 2020c;Ferreira et al, 2021;O'Neil et al, 2019;Baltima et al, 2021); Brazilian Chemical Society (Cardoso et al, 2020a), Royal Society of Chemistry (Elbardisy et al, 2020) and Multidisciplinary Digital Publishing Institute (Vlachou et al, 2020).…”

3D printing is a type of additive manufacturing (AM), a technology that is on the rise and works by building parts in three dimensions by the deposit of raw material layer upon layer. In this review, we explore the use of 3D printers to prototype electrochemical cells and devices for various applications within chemistry. Recent publications reporting the use of Fused Deposition Modelling (fused deposition modeling®) technique will be mostly covered, besides papers about the application of other different types of 3D printing, highlighting the advances in the technology for promising applications in the near future. Different from the previous reviews in the area that focused on 3D printing for electrochemical applications, this review also aims to disseminate the benefits of using 3D printers for research at different levels as well as to guide researchers who want to start using this technology in their research laboratories. Moreover, we show the different designs already explored by different research groups illustrating the myriad of possibilities enabled by 3D printing.

“…Following our previous work on polymeric metal complexes based on oxalamide ligands, [62][63][64][65][66][67][68] we here-in present two families of Cu 2 + /Ln 3 + complexes based on a Cu 2 + "metalloligand" obtained by the act of Cu 2 + on the newly synthesized N,N'-bis(2-hydroxy-4-carboxyphenyl)oxalamide (H 6 L). Specifically, compound (Et 4 N) 4 [CuL] • 13H 2 O (A) (where L 6-is the hexaanion of H 6 L) containing the tetra-anionic [CuL] 4À complex was isolated in high yield from the reaction of Cu 2 + nitrate and H 6 L under basic conditions.…”

Employment of N,N′‐bis(2‐hydroxy‐4‐carboxyphenyl)oxalamide (H6L) in Cu2+ chemistry afforded the mononuclear complex (Et4N)4[CuL] ⋅ 13H2O (A) which comprises a square planar [CuL]4− complex with several O donor atoms in its periphery. The 1 : 1 reaction between complex A and Ln(NO3)3 ⋅ xH2O (Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb, x=6 or 9) in 1 : 4 mixture of ethanol/water in the presence of excess of KCl yielded two families of isomorphous 3d/4f coordination polymers, namely (Et4N)0.5[K0.5(H2O)Ln(H2O)4(CuL)] ⋅ 3H2O [Ln=La(1), Ce(2), Pr(3), Nd(4), Sm(5), Eu(6) and Gd(7)] and [K(H2O)Ln(H2O)4(CuL)] ⋅ ⋅6H2O [Ln=Tb(8), Dy(9), Ho(10), Er(11) and Yb(12)]. The crystal structures of 2–4 revealed the presence of 3D coordination polymers while the crystal structure of 9 the presence of a 2D coordination polymer. In both 3d/4f families, complex A retains its original structure and serves as a “metallo‐ligand”. The magnetic properties of 2–4, 7–9, 11 and 12 are discussed.

“…In addition, FDM enables the single‐step fabrication of multimaterial sensors using filaments with different properties (e.g., conductive and non‐conductive) via multiple extruder 3D printers. [ 20–23 ] Therefore, this revolutionary technology allows the on‐demand fabrication of integrated sensors, which can be produced within a medical setting, thus meeting the core request for specialized biosensors at the point‐of‐care.…”

The in‐house and on‐demand fabrication of electrochemical integrated biosensors is a great challenge, especially in the field of modern point‐of‐care diagnostics. 3D printing technology allows the production of specialized electronic devices adapted to the required conditions, and 3D printed thermoplastic electrodes have shown hopeful achievements mainly in enzymatic bioassays. This work describes a novel configuration of integrated all‐3D‐printed electrochemical microtitration wells (e‐wells) for direct quantum dot‐based (QDs) and enzymatic bioassays. The e‐wells enable the in situ development of complete bioassays, that is, from sample addition to biomarker detection, without the need for external equipment other than a micropipette and a detector. The bioanalytical capability of the 3D e‐wells is demonstrated through the voltammetric bioassay of C‐reactive protein employing biotinylated reporter antibody and streptavidin‐conjugated CdSe/ZnS QDs. In addition, in order to extend their scope to enzymatic biosensing, e‐wells are applied to the amperometric determination of hydrogen peroxide by‐products, demonstrating their universal applicability in electrochemical bioassays.
