For the synthesis of the ILs, choline hydroxide in methanol [Cho][OH]/MeOH 45%, methanol, Amberlite® IRA-400 chloride form, 1-bromoethane, and glycine from Sigma–Aldrich (Saint Louis, MO, USA) were used as well as 1-methylimidazole and acetonitrile from VWR (Fontenay-sous-Bois, France) and sodium hydroxide (NaOH) from PanReact AppliChem (Barcelona, Spain). Rutin was obtained from Fragron (São Paulo, Brazil).
Regarding the cell viability studies, trypsin, penicillin–streptomycin solution, fetal bovine serum, dimethyl sulfoxide (DMSO), and thiazolyl blue tetrazolium bromide (MTT) were acquired from Sigma–Aldrich (Saint Louis, MO, USA) and Dulbecco’s modified Eagle’s medium (DMEM) was purchased by Biowest (Nuaillé, France).
For the preparation of transfersomes, methanol was from Carlo Erba Reagenti SpA (Rodano, Italy), chloroform from Sigma–Aldrich Chemie Gmbh (Munich, Germany), Tween® 80 from Sigma–Aldrich (Saint Louis, MO, USA), and soy phosphatidylcholine from Alfa Aesar (Kandel, Germany). For the release study, phosphate-buffered saline (PBS, pH 7.4) was prepared as previously described [54 (link)].

Reagents (1-methylimidazole, 1-chlorohexane, 1-bromoethane, 1-bromobutane, 1bromohexane, 1-iodohexane, copper(I) halides) were purchased from Sigma Aldrich and used without further purification. Hydrogen (99.9995% HP grade) and carbon monoxide (99.9% CP grade) were supplied by BOC. Gas mixtures containing CO:H 2 and CO:N 2 (each 50:50 (±2)) were supplied by BOC. N 2 gas for inert atmosphere work, and for use in high pressure reactions was supplied by an in-house generator. 13 CO (< 5% 18 O, 99% 13 C) was purchased from Sigma Aldrich and used directly from the cylinder. The 1-alkyl-3methylimidazolium halide [C n mim]X salts were prepared by the reaction of 1-methyl imidazole with the requisite alkyl halide according to published procedures (see ESI). [71] [72] [73] The hygroscopic salts were stored under nitrogen.
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.
