1. How would you detect your sample?
   1. High throughput- optical vs non-optical (Capacitive sensing- frugal, detects deviation in dielectric constant)
   2. Plankton-scope-
   3. Plastic v/s non-plastic
      1. What kind of plastic?
2. Source of microplastics- where does it start degrading, river or ocean or do citizens deploy it?
3. Who is the audience?
   1. community based- citizen science
   2. or scientist
4. What kind of device- outside or inside water?
   1. Design consideration:
      1. Density of the plastic- vertical distribution
      2. Test case- what's the highest throughput?
      3. Size, property of the material
5. Narrow down the topic, audience
