Microscopic Particle Detector Using Laser Microscopy and Image Processing

Updated: Jan 16

By Kyle Tianshi

What is the Problem? 

The invisible TSS (Total Suspended Solids) in water source is becoming a problem with ever-growing plastic contamination. 83% of bottled water and 93% of tap water contain microplastics. My goal was to develop a TSS detector that could measure invisible particles. 

What is Your Solution?

Utilizing an innovative combination of lasers and video image processing, I proved the concept that it is feasible to develop a TSS detector that can measure invisible articles as small as 0.1 microns at concentration of 10ppm. The measurement is accurate and fast. I build a mockup design with a cost of $35 when purchasing individual parts from Amazon. I expect the cost will go down to as low as $15 for mass production.

A program of WE IMPACT Corp, a 501(c)(3) non-profit company 

A student-run enviromental advocacy program founded by Emily Tianshi and Kyle Tianshi. Concerned about the global water crisis and water pollution, they have been conducting scientific research related to moisture harvesting and microplastic contamination from their home lab. Through events and educational programs, they encourage students to share water project ideas, advocate for change via blogs on this website, and utilize their creativity to solve environmental problems.
