The effects of physical and chemical factors of the substrate chemistry and oligonucleotide chemistry on the immobilization process and efficiency were studied. The oligonucleotides terminated by various functional groups were immobilized to functionalized substrates prepared by plasma polymerization. The surface analysis of the propanol surface, immobilized oligonucleotides and immobilized control were performed using X-ray photoelectron spectroscopy (XPS) and time-of-flight- secondary ion mass spectrometry (TOF-SIMS). The effectiveness of oligonucleotides over antibodies as recognition elements in microarrays for high throughput screening were recognized and applied to medical diagnosis and plant pathogen detection.
