ZP Developers Zone 28 July 2024

A weekly webinar from ZP answering technical questions that have come in during the week.

Links from the video:

QUESTION ONE - …ZP’s chloride sensor
QUESTION TWO - … I am a researcher, and I am working on lipase sensing. To do that, I am formulated an enzymatic chain producing H2O2 which I would like to measure…
QUESTION THREE - …I wanted to ask 
…want 10000 SPEs Pyrene NHS Carbon (I believe these will be stable). Could you please also confirm if a DNA monolayer can be made on it?
…does ZP offers a facility where SPE can be functionalised with monolayers of nucleic acid aptamers right after printed may be be with an automated drop casting
…I am aiming to run cohort analysis on the biosensor i developed to measure its impact. Will SPEs based biosensors lets say made in 1M quantity can retain their high quality if stored on shelf for a year? 
…can I also get a quotation for your portable cloud potentiostat? how its different/ better than XXX? as that too is cloud connected?

…did you ever worked on or come across if DNA can be used on your SPEs with high storage stability?
…I aim to make and commercialise a glucometer like biosensor for infectious disease screening. Since you have the manufacturing expertise for SPEs as well as a reader (potentiostat). Can there be a possibility for ZP to be a co-applicant on a research call with academics and later developing into a joint venture? 

QUESTION FOUR - … this regarding 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 that could help 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? E.g. 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 a continuous measurement? Or is there a way to calculate its usage time?
Can the sensor work directly in touch with blood (capillary, venous, or arterial) or interstitial fluid samples without any pre-treatment?
What type of fluids have you been tested with the sensor? What is the difference between the standard and the chloride resistance version?
How resilient would the electrode be against chloride? Could you show any data about it? QUESTION SIX …we want to make smart hepatitis B detection device using electrochemical biosensor method and we need a biosensor and hepatitis b receptor. We require that the biosensor is that it is made up of 3 electrodes gold, platinum and one other metal that is dipped in electrochemical cell and this biosensor is connected to a potentiostat.
