Microscopic Particle Detector Using Laser Microscopy and Image Processing

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 You 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 community outreach program founded by the Tianshi siblings, who are concerned about the global water shortage and water pollution. They have been conducting research related to water from their home lab since middle school. Both of them were named top 30 national finalists in the Broadcom MASTERS, the US's premiere STEM middle school competition. Through events and educational programs, they encourage more children to think about the water crisis, publish creative ideas on this website, and utilize their creativity to solve water and environmental problems.
