Abstract
One of the strategies to overcome the COVID-19 disease is through RT-PCR test. The RT-PCR test is initiated by extraction of nucleic acids which requires silica column. Silica Coarse (SC) in the form of suspension, powder and discs columns- were prepared from kaolinite as an alternative extraction column to binding Ribonucleic acids (RNA). The RNA binding ability in SC was enhanced with chaotropic ions, embedded on the kaolinite framework. SC, then were studied its characterizations using FTIR, XRD, XRF, SEM, and BET measurement. This work shows that SC suspension column could extract RNA that amplified better in RT-PCR test than SC powder and discs columns.
