PEDOT:PSS (CleviosTM P, Heraeus Holding GmbH, Hanau, Germany) was used without further purification. The solid content, viscosity, and weight ratio of PEDOT to PSS were 1.2%, less than 150 mPa·s, and 1:2.5, respectively. Tannic acid powder (Sigma-Aldrich (Burlington, MA, USA), dimethyl sulfoxide (DMSO, 99.0%, Sigma-Aldrich (Burlington, MA, USA), and silver paste (>75%, Sigma-Aldrich (Burlington, MA, USA) were purchased from Sigma-Aldrich.
Tannic acid powder
Manufactured by Merck Group
Sourced in United States
Tannic acid powder is a naturally occurring plant-based compound that can be used as a laboratory reagent. It is a yellowish-brown crystalline powder that is soluble in water and alcohol. Tannic acid is commonly used as a precipitating agent, pH indicator, and astringent in various research and analytical applications.

Tannic acid powder containing 90% tannin was obtained from Sigma-Aldrich (St. Louis, MO, USA). The tannic acid contained gallic acid, monogalloyl glucose, digalloyl glucose, trigalloyl glucose, tetragalloyl glucose, pentagalloyl glucose, ESA galloyl glucose, EPTA galloyl glucose, and octagalloyl glucose. The product is hydrolyzable tannin obtained from oak gall nuts from Quercus infectoria.

Tetraethyl orthosilicate (TEOS), 3-Aminopropyltriethoxysilane (APTES), sodium acetate trihydrate, acetic acid (C2H4O2), 2,4,6-tripyridyl- s-triazine (TPTZ), and tannic acid powder were purchased from Sigma-Aldrich (USA). Iron (II) sulfate heptahydrate (FeSO4.7H2O), ammonia solution (32 %), methanol (99.9 %), and ethanol (96 %) were purchased from MERCK. Then, the aspartate aminotransferase (AST), alanine aminotransferase (ALT), and Alkaline Phosphatase (ALP) were measured via the enzymatic method by Pars Azmoon (Tehran, Iran) kits. Moreover, the Ferric Reducing Antioxidant Power (FRAP), 2,2,1-diphenyl-1-picrylhydrazyl (DPPH), Thiobarbituric acid reactive substances (TBARS), thiol groups, and Advanced Oxidation Protein Products (AOPP) assay kits were obtained from Zantox (Birjand, Iran). Finally, the total nitric oxide kit was purchased from ZellBio GmbH (Germany).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
