Potential diagnostic and distinguishing roles of microneedle-based biosensors in bacterial and aseptic meningitis

Abstract

Meningitis, which is defined by inflammation of the meninges, is a major cause of death and morbidity worldwide. Traditional diagnostic approaches, such as imaging procedures and the study of cerebrospinal fluid, are intrusive, time consuming and sometimes non-specific. The suggested approach entails creating a biosensor based on microneedles that can detect in real time without the requirement for labels. The biosensor uses highly sensitive detection techniques to detect changes in ionic current and modulation of impedance in response to biomolecules that are of interest, such as proteins and nucleic acids, which are linked to meningitis infections. Initial studies have shown that the microneedle-based biosensor for meningitis diagnosis is both feasible and effective. When it comes to identifying bacterial and aseptic meningitis biomarkers from blood and cerebrospinal fluid (CSF) samples, the biosensor showed excellent sensitivity and specificity. This novel technique has the potential to enhance patient outcomes by facilitating prompt intervention and tailored therapy by offering a quick, safe and accurate way to distinguish between bacterial and aseptic meningitis. To maximise the biosensor's performance and confirm its therapeutic usefulness in various contexts, more investigations and advancements are necessary.
