15/12/2021 (WEDNESDAY)
- Briefing with our sv, Dr. Aisyah
- Our group has been assigned for the topic of Biosensor to Detect Sulfonomides

# data[].attributes.body
5/1/2022 (WEDNESDAY)
- Updating our progress to Dr. Aisyah
- Our design of biosensor was still using 2D hand drawing
- However, Dr. Aisyah asked us to show 3D design using any suitable software for our next class meeting

# data[].attributes.body
22/12/2021 (WEDNESDAY)
- We updated our progress to Dr. Aisyah
- Discussed about our findings and asked some questions for better understanding

# data[].attributes.body
12/1/2022 (WEDNESDAY)
- 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

19/1/2022 (WEDNESDAY)
- Final update on our progress before pre-recording

# data[].attributes.body
- 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

# data[].attributes.body
- We discussed on the design improvement based on Dr. Aisyah's comments
- We divided the task among us:
Biosensor 3D design: Farah
Electrode mechanism/working principle: Azra and Yuni
Calculation on SMX concentration percentage: Sharifah and Era

# data[].attributes.body
- We discuss regarding the task given in the jamboard
- We divided the task among group members to complete the information for each objective in the jamboard
- Each of us also tried to find any journals related to our topic

# data[].attributes.body
- Compare various biosensor types for sulfonamides detection - I find information about magnetic nanoparticles

# data[].attributes.body
- We discussed to decide which mechanism is the best to be applied for sulfonamides biosensor and which type of sulfonamides we will focus
- We chose the electrochemical biosensor for the mechanism
- Type of sulfonamides not yet been decided as we still need to do more research

# data[].attributes.body
- Searched the journal about type of sulfonamides and the approach used to detect it

# data[].attributes.body
- We chose sulfamethoxazole (SMX) as the type of sulfonamides that we will need to detect
- Completing the proposal

# data[].attributes.body
- Studied about percentage of sulfamethoxazole (SMX) concentration in water (safe level-dangerous level value) and what buffer need to be used

# data[].attributes.body
- Studied the articles shared in the group discussion about the materials that can be used for the electrode and their benefits and limitation
- Searched articles/journals related to the calculation on SMX concentration percentage

# data[].attributes.body
- Divided the task for slides and presentation
- Edit and complete the slides for pre-recording

# data[].attributes.body
- All the team members need to record their parts separately and upload it in the Google drive

# data[].attributes.body
- All the team members had submitted their recorded presentation in the Google drive
- Yuni had compiled all the videos and edit some parts
- She uploaded the final video presentation in the Youtube and submit the link in the Google form provided

26/1/2022 (WEDNESDAY)
- 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)

Completing the final report
