Article Synopsis
- A new hybrid material was created by modifying a nitrocellulose membrane with amino-polyethylene glycol functionalized reduced graphene oxide nanoparticles to enhance oligonucleotide extraction.
- Characterization techniques like FTIR and SEM confirmed improvements in the membrane's structure and surface properties, showing smoother surfaces and distinct chemical changes.
- The modified membrane demonstrated superior efficiency in extracting single-stranded DNA, especially in magnesium chloride solutions, with a significant increase in DNA recovery compared to the unmodified membrane.
A nitrocellulose-graphene oxide hybrid that consists of a commercially nitrocellulose (NC) membrane non-covalently modified with graphene oxide (GO) microparticles was successfully prepared for oligonucleotide extraction. The modification of NC membrane was confirmed by Fourier Transform Infrared Spectroscopy (FTIR), which highlighted the principal absorption bands of both the NC membrane at 1641, 1276, and 835 cm (NO) and of GO in the range of 3450 cm (CH-OH). The SEM analysis underlined the well-dispersed and uniform coverage of NC membrane with GO, which displayed thin spider web morphology.
