A sensitive assay that used q-MNP–fluorescent polymer
systems to allow the analysis and capture of bacteria has been
demonstrated. In this paper, we have illustrated the assemblies'
kinetics of q-MNP with a PFBT polymer that can provide an
efficient sensor of pathogen. Through application of LDA, the
fluorescence response pattern can be employed to identify
and quantify eight different bacteria by canonical scores in
a rapid, simple, and low-cost way. The sensitivity of this sensor
pattern, which has yet to be fully optimized, presents a potential
approach for detecting pathogenic bacteria, protein, or DNA
analysis.
