Article Synopsis
- A novel microRNA biosensor was developed using magnetic rod carbon paste electrodes and a new MOF structure to detect low levels of microRNA 155 for breast cancer diagnosis.
- A combination of materials like carbon nanofibers and CuBTC-AIA was utilized to enhance the sensor's performance, leading to a very low detection limit of 0.08 fM and a dynamic range of 0.2 fM to 500 pM.
- The biosensor demonstrated high selectivity and reproducibility when tested with different mismatched sequences, successfully detecting microRNA 155 in human serum samples without interference from other substances.
Despite all the psychological advantages of alprazolam, its long list of toxic properties and interactions has caused concern and highlighted the need for a reliable sensing method. In this study, we developed a simple, highly sensitive electrochemical nanobiosensor to determine the desirable dose of alprazolam, averting the undesirable consequences of overdose. Gold nanourchins (AuNUs) and iron-nickel reduced graphene oxide (Fe-Ni@rGO) were immobilized on a glassy carbon electrode, which was treated beforehand.

Carbon nanofibers (CNF), as a highly conductive material, were used to modify a glassy carbon electrode (GCE) and thus increase its conductivity. Moreover, to enhance the immobilization of aptamers (Apt) on the electrode surface, graphene oxide functionalized with aspartic acid (GOAsp) was added to the surface.
