Characterization of nano ink printing with XYZ micro plotter, WSU, Vancouver, WA 1. 2021 - 5. 2022

Objective: To modify an XY plotter device, add Z moving direction with single-walled carbon nanotube ink inside the fountain pen, and test the printing and potential biosensing application characterizations.

· Designed and fabricated a z-direction movement structure with a pen holder on an XY-pottering machine to achieve the goal of two-dimensional mobility

· Produced three different concentrations of nano ink combining single-walled carbon nanotube (SWCNT) with 1% Sodium dodecyl sulfate (SDS) solution as the primary testing subjects

· Tested the three characterizations of the printing patterns (electrical resistance, line width, surface roughness) under different temperature circumstances with a heat plate for single-layer and double-layer printing patterns

· Picked suitable printing pattern and applied silver ink on both ends of line pattern as a metal material, checked the resistance, and tested it as an ion sensor

· Applied the biomaterials (protein/ virus/ bacteria) on the conductive printing pattern to check the potential of interacting with a target sample

Microfluidic Biosensing System, WSU, Vancouver, WA 9. 2019 - 12. 2020

Objective: Designed a deterministic lateral displacement (DLD) device with a functionalized porous structure to capture target cells through physical bonding.

· Checked the characterizations (gap size, line width) of mesh samples and designed the three layers of Polydimethylsiloxane (PDMS) DLD device with SolidWorks to acquire an ideal experiment instrument

· Processed and dried the porous structure with 4M hydrochloric acid under 80oC to get the functionalized samples

· Applied Fourier-transform infrared spectroscopy (FTIR) to check the spectrums of functionalized mesh samples to obtain the best target capturing purpose.

· Tested the tightness of the DLD device with a syringe pump and placed three functionalized mesh samples at three points where liquid was inputted, transferred, and outputted to demonstrate the feasibility of cell capturing

· Applied the bio-sample fluid (blood/ protein) through the microfluidic channel to capture target cells on the donor mesh

Checked the output mesh to see if the remaining cells arrived and prepared for drug delivery test

• Involved in designing and developing the shock absorber components (piston/coil/ spring/rod/cylinder/bolts/mount/bushing) through SolidWorks and Creo Parametric to understand the function and application of each component
• Assembled the shock absorbers manually and learned to operate the CNC automatic assembling machine to understand the principle behind the product assembling and packing process
• Optimized the shock absorbers assembling process by adjusting the PLC program to achieve maximum efficiency
• Maintained and assessed the defective shock absorbers and run the quality testing through the computer for customers
