Solutions were prepared using Milli-Q water (resistivity = 18.2 MΩ.cm), HCl (Alfa Aesar, 36%) and hydroquinone (Aldrich-Chemie, analysis grade). When necessary, NaCl (Fluka analytical) was introduced so that the current flowing through the swimmer is not limited by the overall conductivity of the solution. SDS surfactant (Sigma, ≥98,5%) was added to the solutions in order to promote the formation of homogeneous bubbles and to facilitate their continuous release. The composition of the electrolyte has an impact on the efficiency of a bipolar electrochemical experiment in general and on the swimmer motion in particular. Higher electrolyte concentrations will slow down the motion. However it has been recently shown in a different context that bipolar electrochemistry is even possible in ionic liquids39 (link), which exhibit by definition a very good conductivity.
Sds surfactant
Manufactured by Merck Group
Sourced in United States
SDS (Sodium Dodecyl Sulfate) is a commonly used anionic surfactant. It functions as a detergent, emulsifier, and solubilizing agent. SDS is widely used in various laboratory applications, including protein electrophoresis, Western blotting, and cell lysis.

The substances such as di-n-butyl itaconate (DBI), lauryl methacrylate (LMA), itaconic acid (IA), sodium dodecyl sulfate (SDS) surfactant, potassium persulfate (KPS) initiator, and hydroquinone (HQ) inhibitor were acquired from Sigma-Aldrich (Saint Louis, MO, USA). In addition, ethanol, petroleum ether, sodium hydroxide (NaOH), and ammonia (28 wt % in H2O) were obtained from Fermont (Monterrey, Nuevo Leon, Mexico). The degree of purity of the above substances was of reagent grade. Deionized water (DI-H2O) was used throughout the investigation. Tetrahydrofuran (THF, HPLC grade from JT Baker (Phillipsburg, NJ, USA)) solvent was used in the polymer characterization. Argon gas (Praxair, Danbury, CT, USA) was used to purge the reactor. Cellulose extraction thimbles (Whatman™, Marlborough, MA, USA) were used in gel content measurements. DBI and LMA were purified prior to polymerization, passing them through an inhibitor removal column of basic alumina or Brockmann I (Sigma-Aldrich, Saint Louis, MO, USA). SDS was purified by Soxhlet extraction with petroleum ether for 24 h, followed by recrystallization with absolute ethanol. All other chemicals were used as supplied.

Atenolol, gold(III) chloride trihydrate (HAuCl 4 ), cetyl-trimethyl-ammonium bromide (CTAB), sodium dodecyl sulfate (SDS) surfactant and HPLC grade solvents such as methanol, acetonitrile (ACN) and dimethylsulphoxide (DMSO) were purchased from Sigma Aldrich (USA). A commercial pharmaceutical formulation (Normoten-100, Jazeera Pharmaceutical Industries, Saudi Arabia) was used.
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.
