A smartphone-linked fluorimeter detects infectious disease and cancer biomarkers in 10-minute assays

1

The VPodDuo pocket-size fluorimeter produced results comparable to larger laboratory instruments in various molecular tests.
2

The device measures fluorescent signals from assays, allowing simultaneous assessment of test samples and controls.
3

Detection limits for Zika virus and methicillin-susceptible Staphylococcus aureus were 10,000 copies/µL and 100 copies/µL, respectively.
4

The VPodDuo identified HIV and lung cancer mutations with detection limits of approximately 7 pM and 29 pM, respectively.
5

Further studies are needed to evaluate the VPodDuo's performance with clinical specimens and under varied environmental conditions.
