Abstract:Nasopharyngeal (NP) swab is one of the most effective sampling devices for clinical specimens. However, commercial NP swabs often release samples through diluents, lowering analyte concentration and causing inaccurate detections. Here, we developed 3D-printed open-cell microlattice NP swabs with user-friendly high-efficiency controlled sample release (CR) mode. Compared with traditional NP swabs, our microlattice NP swabs show higher (~7–11 times) flexibility, larger (~2.3 times) and customizable release volum… Show more
