Popis: The present study describes the creation of a 3D printed cassette named “3DP-PAC”, integrated to an electrochemical-aptasensor for the detection of dengue virus. It consists of an electrode cassette printed from a PLA non-conductive filament that provides a sophisticated design & support system to the delicate conductive paper-electrode. Chemically synthesized GO/ZnO-NC was used, which increases the sensor's sensitivity by accelerating the flow of electrons transferring. DENV DNA-Aptamer specifically binds to its target antigen of DENV, confirming its selectivity and demonstrating no cross reactivity with chikungunya virus antigen (CHIKV–Ag). The current study developed a 3D-based aptasensor for detecting dengue virus at a low level of detection (0.1 μg/ml). In human serum, the established platform performed well. This study paves the way for the manufacture of next-generation electrochemical biosensors utilizing 3D printing technology, with possible consequences for healthcare applications on the edge of commercialization.
