Myoglobin (Mb) is a critical cytoplasmic heme protein and one of the earliest detectable biomarkers following acute myocardial infarction (MI). The rapid precise detection serum Mb holds significant clinical value. This study capitalizes on advantages split aptamer (Apt) sequence, which short effectively minimizes false-positive signals caused by secondary structure probe. It constructs "sandwich"-structured liquid crystal biosensor with an "Apt-target molecule-Apt" configuration for label-free Mb. Apt fragments were immobilized surface glass substrate as capture probes (CP) using triethoxybutanal silane (TEA) linker molecules. When present, other fragment, signal probe (SP), specifically binds reassociates CP, restoring original stem-loop Apt, thereby inducing change in alignment 5CB leads to variations brightness color optical polarizing microscope image, facilitating quantitative method capable detecting concentrations ranging from 0.05 130 ng/mL, minimum limit 0.045 ng/mL. sandwich biosensing offers several advantages, including detection, operational simplicity, high specificity. demonstrates potential biomarkers.
