Baek et al. reported a new study has developed a 3D microfluidic analysis device (μPAD) for the simultaneous detection of multiple biomarkers, including albumin, using a smartphone. The 3D-μPADs were fabricated using a 3D digital light processing printer and consisted of a sample reservoir connected to 24 detection zones through eight microchannels. Eight different biomarkers related to various diseases, including albumin (0-7 g/dL), were detectable in concentrations ranging from normal to abnormal conditions. The device has potential as a cost-effective platform for point-of-care testing and disease diagnosis. The researchers suggest that with further development, 3D-μPADs could allow patients to easily diagnose diseases remotely using a smartphone at home in the future.
