Researchers in China have used Projection Micro Stereolithography (PµSL) to improve the fabrication of micropillar array electrodes (µAEs) for the identification and detection of biomarkers. PµSL, a micro-precision 3D printing technology from Boston Micro Fabrication (BMF), enabled researchers to produce 3D printed molds for reduced fabrication costs and increased device sensitivity. Most µAEs are fabricated…
