In August of 2022, I had an opportunity to work with the researchers of NanoHelix Co., Ltd., a biotechnology company that provides molecular biological reagents and raw materials for molecular diagnostics internationally. Throughout my time there, I investigated and analyzed the current diagnostic methods for COVID-19, including the polymerase chain reaction (PCR) and the rapid lateral flow antigen tests for SARS-CoV-2. Specifically, I went through the testing procedure of PCR from creating a mixture of the raw materials to running and interpreting the test results from the PCR machine.
