Abstract—We designed high-throughput microchip which detects single nucleotide polymorphisms (SNPs). The chip consisted of DNA extraction part and SNP detection part. DNA was extracted by lysis buffer, and then amplified by polymerase chain reaction (PCR). In SNP detection part, CEL I endonuclease selectively cleaved mismatched dsDNA, so wild type DNA was distinguished from mutant type. Signal was detected by colorimetric assay using magnetic nanoparticles-H2O2-ABTS detection system.

I. INTRODUCTION
Single nucleotide polymorphisms (SNPs) comprise the most abundant source of genetic variation in the human genome. A SNP is a DNA sequence variation occurring when a single nucleotide — A, T, C or G — in the genome (or other shared sequence) differs between members of a biological species or paired chromosomes in an individual. SNPs may be linked to genetic predispositions, frank disorders or adverse drug responses, or they may serve as genetic markers in linkage disequilibrium analysis.[1] Thus, the more recent SNP concept has basically arisen from the recent need for very high densities of genetic markers for the studies of multifactorial diseases, and the recent progress in polymorphism detection and genotyping techniques.[2] For these reasons, efforts to detect SNPs are ongoing nowadays, and need for faster and more convenient detection is emerging.
