A weekly webinar from ZP answering technical questions from the week.

QUESTION ONE – In this video we demonstrate how to clean a screen printed electrode.

QUESTION TWO – Sensors for Dialysis Monitoring.

….in the video you have designed a wonderful sensor sir. why are  you using linear sweep voltametric analysis instead of differential pulse voltammetry and chronoamperometry?

What is the life expectancy of sensor ? Is it reusable ?

QUESTION THREE – Glassy carbon electrodes, graphite electrodes and screen printed electrodes.

Thank you so much sir for the video link. I watched the video, and it was good. I have one question related to cleaning. If you are using the conc. sulfuric acid, there is a chance of affecting the lifetime of the screen printed electrode, right? Can you explain that? In many papers I came to know that people are using GCE as a reference electrode even though the graphite electrode is cheap and efficient. What is the reason for that also?

QUESTION FOUR – Teaching STEM…if your sensor reader or meter can simultaneously read both the Bacteria and Spectrum sensors, wouldn’t that effectively make it a multifunctional device capable of detecting both bacteria and heavy metals at once? That would be incredibly useful. The SenseItAll Instrument is truly impressive – that’s actually what inspired my students. They’re hoping to build a simplified, budget-friendly version using a microcontroller, a display, a sensor, and a sensor reader. Do you think that’s feasible? And would it be possible to integrate both Biosensors and Electrochemical Sensors in one system?
