- Updating our 3D design of biosensor progress
- Dr. commented regarding our design:
Our biosensor design is too big and the electrode design needs to change to a simpler design.
- Dr. also explained the general concept of biosensor mechanism based on articles]]> 2022-01-31 06:49:43 UTC https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2020694514 Last Class Meeting nuramira2 https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2020698110 19/1/2022 (WEDNESDAY)
- Final update on our progress before pre-recording ]]> 2022-01-31 06:53:32 UTC https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2020698110 Group Discussion nuramira2 https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2020704691 - Sharifah suggested to use TinkerCAD software for the 3D design as it is an online software and we can edit it together
- We discussed on several things:
1. Search
  • Mechanism of detection of smx (eg: oxidation process of Tyr when there are smx)
  • Material for casing which better PLA or thermoplastic resin
  • Percentages of smx concentration in water (safe level- dangerous level value)
  • What buffer need to be used and why
2. Biosensor design 
  • Display (percentages of smx concentration in wastewater; level of severity; voltage use)
  • On the device have : button to increase voltage; led with multicolor; place to keep the electrode
  • Dimensions : 95 x 120 mm
  • LCD dimensions: 64 x 80 mm
  • Electrode using screen-printed carbon electrode that will be immobilized with Tyr by crosslinking it with GA

- Comments from the panels:
1. Problem Statement
- Health threat (specify)
- Limitation from early detection (SWNCT)
- Costly, time-consuming (Other Biosensor compared to Electrochemical)
2. Methodology
- Fabrication process (This picture is adapted from..... )
- Design consideration (small size, simplicity of strip)
3. Discussion
- Why did we choose TinkerCad
- Future research (nanoparticles that need to be used because of the drawback from MWNCTs, use Solidworks for simulation)]]> 2022-02-04 08:43:23 UTC https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2029076264 nuramira2 https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2029077331 Completing the final report]]> 2022-02-04 08:44:24 UTC https://padlet.com/nuramira2/jmkgmh6k4ikbfjg8/wish/2029077331
