Material and method for diagnosis of traumatic brain injury

Abstract

Materials and methods for the diagnosis of traumatic brain injury using miRNA biomarkers are disclosed. Amplification nucleotide chains amplify a detectable signal indicating the expression and/or upregulation of the biomarkers. Detection of the amplified signal is accomplished with capture nucleotide chains in a stem-loop conformation. The loop sequence of the capture nucleotide chains binds with the biomarkers and/or an indicator nucleotide chain released in the presence of one or more of the biomarkers. Binding is detected with indicators on one or more of indicator nucleotide chains released during amplification, the capture nucleotide chains, and signal nucleotide chains capable of complementary base-pair binding to the capture nucleotide chains. Incorporating the foregoing into a lateral flow assay permits point of care diagnosis.
