Carbon screen-printed electrodes (Dropsens DRP 11L), with carbon working and counter electrodes and a Ag/AgCl reference electrode, were bought from Metrohm (Herisau, Switzerland). Tetradodecylammonium nitrate (TDDA), high-molecular-weight poly (vinyl chloride) (PVC), 2-nitrophenyl octyl ether (NPOE), tetrahydrofuran (THF) stabilized with BHT, potassium chloride, and sodium nitrate were bought from Sigma Aldrich (Burlington, MA, USA). An EmStat Pico module (portable potentiostat) was purchased from PalmSens (Houten, the Netherlands). Gaussian software Gaussian 16 W, version 1.1 (Wallingford, CT, USA), was used to perform the computational study. Illustrative sketches were drawn using BioRender. All statistical analysis was conducted using GraphPad Prism, version 9.3.1 (San Diego, CA, USA).

Electrical Impedance Spectroscopy Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols

Measurements of electrical impedance spectroscopy (EIS) were performed at predetermined time points. Multichannel potentiostat (VPM-300) purchased from BioLogic Science Instruments (Seyssinet-Pariset, France) was used to characterize the different designs of impedance sensors. EmStat Pico module (development kit) purchased from PalmSens was used for the measurement of electrochemical signals during the cell cultures. PSTrace software (V5.8.1) was employed for the electrochemical data processing (frequency scanning range of 50 kHz–5 Hz). For electrode materials’ characterization, a classical three-electrodes cell (Ag/AgCl reference and carbon counter electrodes) was used. All other EIS experiments were conducted using the two-electrodes set-up previously described.

Potentiometric Measurements with Portable Probe

Check if the same lab product or an alternative is used in the 5 most similar protocols

Potentiometric measurements on the eld were performed using an EmStat Pico module (Palm Sens, Houten, The Netherlands) located inside the probe. This whole module is designed around an STM32L476 microcontroller running on an operating system called Chibios. The probe is equipped with a PT1000 temperature probe using a MAX31865 chip. The data is stored internally on a microSD card located on the main board (Fig. S1 †). To perform time-based measurements, an integrated clock with a CR2032 battery is mounted internally.
To perform the calibration step, two small KMPP peristaltic pumps (Kamoer Fluid Tech, Shanghai) were added to the sensing head. The pumps are controlled by a Grove I2C Motor (TB6612) module that can control two pumps. The pumps and the main board are powered by 4 Li-ion batteries (3500 mA h-3.6 V). The main reference electrode was a simple Ag/AgCl coated wire (Metrohm AG, Switzerland).

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.
