Figure 5. (a) Fluorescent photographs, (b) signal responses,
and (c) calibration curves of
MANP-FLIA test strips in response to
different concentrations of LAM (0–20 ng mL−1) in
urine with/without magnetic enrichment and separation. (d) Specificity
evaluation of the proposed MANP-FLIA platform toward various
mycobacteria species with a
bacterial concentration of 2.5×104 CFU
mL−1. (e) Fluorescent signal of MANP-FLIA when adding
different concentration levels of LAM into urine samples provided by
10 individual healthy people. (f)
Diagnosis result of clinical TB-positive patients and healthy
individuals obtained using MANP-FLIA.
