A weekly webinar from answering a technical questions that have come in during the week. The questions and answers are anonymized, and the webinar is recorded so no need to watch live.
QUESTIONS
QUESTION ONE
- ZP’s chloride sensor
QUESTION TWO
- I am a researcher working on lipase sensing. To do this, I have formulated an enzymatic chain producing H2O2, which I would like to measure.
QUESTION THREE
- I would like to request 10,000 SPEs Pyrene NHS Carbon (I believe these will be stable). Could you please also confirm if a DNA monolayer can be made on them?
- Does ZP offer a facility where SPEs can be functionalized with monolayers of nucleic acid aptamers right after printing, possibly with automated drop casting?
- I aim to run cohort analysis on the biosensor I developed to measure its impact. Will SPE-based biosensors, if made in quantities of 1M, retain their high quality if stored on a shelf for a year?
- Can I also get a quotation for your portable cloud potentiostat? How is it different or better than XXX, as that too is cloud-connected?
- Have you ever worked on or come across the use of DNA on your SPEs with high storage stability?
- I aim to make and commercialize a glucometer-like biosensor for infectious disease screening. Since you have the manufacturing expertise for SPEs as well as a reader (potentiostat), could there be a possibility for ZP to be a co-applicant on a research call with academics and later develop into a joint venture?
QUESTION FOUR
- Regarding the wafer holder for ED: How can I apply constant voltage or current to the whole wafer? Where is the connection?
QUESTION FIVE
- I was searching for electrochemical sensors to help with my experiments or product developments, and I found the sodium sensor on your website. I am writing to request more information about your sensor besides the technical datasheet. Here are my questions:
- What is the reportable sensing range of the sensor? For example, the i-STAT CG8 range is 100-180 mmol/L (mEq/L) for sodium.
- What is the least required sample volume?
- What is the limit of detection, i.e., the lowest concentration of analyte that the sensor can detect?
- How long can the sensor last for continuous measurement? Or is there a way to calculate its usage time?
- Can the sensor work directly in contact with blood (capillary, venous, or arterial) or interstitial fluid samples without any pre-treatment?
- What types of fluids have you tested the sensor with?
- What is the difference between the standard and the chloride-resistant version?
- How resilient would the electrode be against chloride? Could you show any data about it?
QUESTION SIX
- We want to make a smart hepatitis B detection device using the electrochemical biosensor method. We need a biosensor and hepatitis B receptor. The required biosensor should be made up of three electrodes: gold, platinum, and one other metal that is dipped in an electrochemical cell and connected to a potentiostat.
