DSG3 and head and neck squamous cell carcinoma: For instance, a microfluidic sandwich ELISA for the chemiluminescence‐based detection of neck squamous cell carcinoma (HNSCC) metastasis, accompanying protein biomarkers (desmoglein 3 (DSG3), and vascular endothelial growth factors‐A/C (VEGF−A/C), was developed by Sharafeldin et al.[191] This PA‐based, SLA‐printed microfluidic device was capable of lysing cells through a 2 s ultrasonic pulse and quantifying released proteins in a reaction chamber with a LOD in the fg mL−1 range.
