Here, the hydrophobic alkane COP was modified to have carbonyl functionalities through oxygen plasma and chemical etching treatments to increase usefulness for chemical and biochemical applications. Then, biotin-hydrazide was used to create biotinylated surfaces that bound streptavidin. A biotinylated target oligonucleotide was subsequently bound to the immobilized biotin-streptavidin and ligation mediated rolling circle amplification-based (L-RCA) SNP detection was demonstrated.展开更多
