Abstract

A method of using an exchange-induced remnant magnetization (EXIRM) technique for label free detection of short strands of nucleotides and cancer biomarkers, such as DNA and microRNA strands, DNA/RNA-binding biomarkers, and cancer-specific antigens, with high sensitivity, high specificity, and broad dynamic range. The method may provide a label-free approach aimed to facilitate high reliability, and to require a minimum amount of biochemical reagents.
