“…3A demonstrates that Pt surface is partly covered by Bi specie as expected, because of the obviously decreased integrated areas of hydrogen adsorption/desorption peaks. In addition, the apparently increased oxidation at about 0.9 V and reduction peaks at 0.7 V of NPG-PtBi could be generally ascribed to the superposition of oxides formation and reduction of Pt and Bi31.…”

“…Unfortunately, its active sites are so easily poisoned by unexpected intermediates such as CO causing performance deterioration30. Therefore, bimetallic electrocatalysts, such as PtRu, PtAu, PtPd, PtBi are developed to reduce the poisoning of platinum surface, which can suppress adsorption of poisoning intermediates31323334. Among these choices, Bismuth wins more opportunities due to its cost advantage313536.…”

Binary PtBi decorated nanoporous gold (NPG-PtBi) electrocatalyst is specially designed and prepared for the anode in direct glucose fuel cells (DGFCs). By using electroless and electrochemical plating methods, a dense Pt layer and scattered Bi particles are sequentially coated on NPG. A simple DGFC with NPG-PtBi as anode and commercial Pt/C as cathode is constructed and operated to study the effect of operating temperatures and concentrations of glucose and NaOH. With an anode noble metal loading of only 0.45 mg cm−2 (Au 0.3 mg and Pt 0.15 mg), an open circuit voltage (OCV) of 0.9 V is obtained with a maximum power density of 8 mW cm−2. Furthermore, the maximum gravimetric power density of NPG-PtBi is 18 mW mg−1, about 4.5 times higher than that of commercial Pt/C.

Metallic Bi and Ni were co‐deposited onto the surface of glass carbon electrode (GCE) from the electrolyte solution containing their respective nitrate to fabricate a Bi/Ni alloy modified GCE (Bi/Ni‐GCE). The purpose is to study the influence of Bi3+ on the deposition of Ni and that of deposited Bi on the electrocatalytic performance of Ni to glucose in alkali solution. The results show that both redox signal of Ni(OH)2/NiOOH and Ni(OH)2/NiOOH mediated electrocatalysis to glucose is remarkably increased in the presence of Bi. It seems that there is a synergistic effect between Bi and Ni on each other’s redox electrochemistry. It’s possible that the firstly deposited Bi on GCE surface helps to the following nucleation and growth of Ni, leading to the deposition of more metallic Ni on GCE surface. An extremely attractive feature of Bi/Ni‐GCE is reflected by the fast response time to the electrocatalytic oxidation of glucose. The electrode nearly responses immediately after glucose is added and it reaches a steady‐state level within only 2 seconds, demonstrating a good electrocatalytic property of Bi/Ni‐GCE. The calibration plot is linear over the wide concentration range of 0–5.8 mM with a sensitivity of 33.96 µA/mM and a correlation coefficient of 0.9985. The detection limit of the glucose was found to be 0.59 µM at a signal‐to‐noise ratio of 3. The fabricated Bi/Ni‐GCE was successfully employed to analyze the glucose level in blood samples, exhibiting high accuracy, strong resistance against inference and good reliability in the practical applications.

“…Most likely, the synthesis of soluble bismuth complexes may provide evidence to explain the exact reason about the nontoxicity of bismuth-containing compounds. Due to these attractive characteristics, fundamental research of bismuth chemistry has been prompted in several fields including use in organic syntheses, industrial use as precursors in advanced materials science, sensing applications [4][5][6], bioactivity like treatment of a variety of gastrointestinal disorders, antitumor, antimicrobial, and antibacterial activities [7]. The first bismuth-containing medicine reported in 1786 for the treatment of dyspepsia was marked as the beginning of the medical use of bismuth complexes [8].…”

This paper reviews the synthesis and biomedical applications of bismuth complexes with unusually low toxicity and excellent clinical performances, summarizes their main synthesis methods, and biomedical applications as drugs for the therapeutic treatment of gastrointestinal disease, Helicobacter pylori infection, and various cancers; especially, describes the development of bismuth-based MOFs in the drug delivery and potential application in cancer treatment. *Corresponding authors.A variety of bismuth complexes have been extensively explored in biomedical applications. The well-known low toxicity and environmental friendliness of bismuth salts make them valuable for large-scale synthesis of various bismuth-based complexes, which become more significant as active pharmaceutical ingredients of medical products. Bismuth complexes have been widely and preferably used in biomedicine with satisfactory therapeutic effect, which is highlighted in this review. However, their synthesis methods have been scarcely summarized. The classification of the main synthesis methods of bismuth complexes has been done here, followed by updates of the relevant advances concerning applications in biomedicine such as therapeutic effect on gastrointestinal diseases, antimicrobial, and anticancer activities, and the description of the side effect and biotoxicity resulting from long-term use of bismuth as well. Bismuth containing metal-organic frameworks, newly developed bismuth-based materials, are also discussed here, becoming a hot research topic recently. An outlook for future study on the potential use of bismuth complexes in biomedicine is provided in the end.
