Magnetic Glyco-nanoparticles: A Unique Tool for Rapid Pathogen Detection, Decontamination, and Strain Differentiation
Abstract
Many pathogens use mammalian cell surface carbohydrates as anchors for attachments, which subsequently results in infection. The unique combination of magnetic nanoparticles and diverse carbohydrate bioactivities prompts us to develop a magnetic glyco-nanoparticle (MGNP)-based system to rapidly detect Escherichia coli ( E. coli ) in just 5 min. High capture efficiencies up to 88% were achieved. Moreover, to accurately differentiate three E. coli strains, response patterns of MGNPs were utilized to decipher the pathogen identity. This appealing approach may have clinical applications since the virulence of many pathogens can be correlated with carbohydrate binding specificity. To the best of our knowledge, this is the first time that MGNPs have been used to detect, quantify, and differentiate E. coli cells, which can provide an exciting new avenue for decontamination and diagnostic applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
