| Abstract Scope |
This presentation will explore the integration of several types of electrode materials, including nanostructured materials, with hollow microneedle-based biosensors. In one study, we prepared a 3D-printed conducting microneedle array-based electrochemical point-of-care device for the detection of chlorpromazine. The microneedle array-based three-electrode device was utilized for the detection of chlorpromazine; the device demonstrated a good linearity range from 5–120 μM and a low detection limit (0.09 μM) (DOI: 10.1039/D4TB01808G). In another study, a 3D-printed conducting microneedle-based electrochemical sensing device was used for the determination of buprenorphine levels. 3D printing and air spray coating methods were used to prepare a conducting microneedle surface. The device was used to detect buprenorphine levels in fluid; the system demonstrated a detection range of 2-140 μM and a limit of detection of 0.129 μM (DOI: 10.1007/s00604-024-06754-x). These studies indicate that 3D printing techniques can be utilized to create low-cost electrochemical sensors for detecting biologically-relevant chemicals.
