제목 Sub-nanogram Level Biomarker Capturing by Nanoporous Microneedles
초록 Minimally invasive microneedle (MN) patches have shown its potential for the rapid detection of biomarkers toward diagnostic point-of-care testing. However, achieving sufficient detection sensitivity for target molecules is a significant challenge. Here we present a highly sensitive detection platform using nanoporous MNs, enabling a rapid capturing of biomarkers present at sub-nanogram level. The uniform nanopore arrays on the MN surface was prepared by a controlled anodization process and then the nanoporous MNs were functionalized by the immobilization of biomarker-specific antibody to detect a target biomarker based on an immunoassay method. The bio-functionalized MN patch showed a rapid capture of estradiol known as a biomarker of preeclampsia following 1 min incubation time. The nanoporous MN platform can be employed to detect diverse biomarkers including metabolites and proteins and could be integrated into a handheld system for point-of-care clinical diagnostics.
