In situ controllable heterojunction conversion strategy driven by oriented paper-based fluid transfer for human immunoglobulin G detection

Mercury ions (Hg 2+ ) mediating in situ heterojunction formation strategy based on spatially separated dual working areas was developed to achieve sensitive detection of human immunoglobulin G. To be specific, the complex of antibody, the silicon dioxide, and thymine-rich hairpin DNA were immobilize...
