| dc.description.abstract | Microplastic contamination is an emerging contaminant and concern that can be found all over the planet. These microplastics are often very tiny in size; therefore, they can readily pass though bedrock and infiltrate water bodies such as rivers, lakes, and seas. Whenever such environmental contamination occurs, the first step in order to address the issue is to characterize the contamination in order to define its origin. This project proposes a design of a microfluidic chip, which is integrated with a Surface Enhanced Raman Spectrometer to characterize microplastic particles in various aqueous solutions such as water. The proposed design is capable of sorting and collecting microplastics based on their size without any need for a membrane. It also has a flat architecture, which makes it easy to manufacture at a reasonable cost. SolidWorks was used for the computer aided design (CAD) of the microfluidic chip and COMSOL Multiphysics was utilized for computer aided engineering (CAE) calculation to verify the design. According to the calculations, this microfluidic chip is capable of size-based sorting of microplastics. | |
