Non-invasive mouthguard biosensor for continuous salivary monitoring of metabolites

Abstract

A wearable mouthguard electrochemical biosensor for salivary metabolites is described. Such non-invasive mouthguard metabolite biosensors provide real-time information regarding a wearer's health, performance and stress level, and thus hold considerable promise for diverse biomedical and fitness applications.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The mouthguard lactate device is capable of detecting salivary lactate electrochemically in connection to selectivity imparted by the lactate oxidase enzyme; protection against biofouling in undiluted human salivary samples was conferred by electro-polymerized ortho-phenylenediamine (OPD) for continuous, non-invasive physiological monitoring of an individual's fitness state.

    “This device is capable of detecting salivary lactate electrochemically in connection to selectivity imparted by the lactate oxidase enzyme; protection against biofouling in undiluted human salivary samples was conferred by electro-polymerized ortho-phenylenediamine (OPD) for continuous, non-invasive physiological monitoring of an individual’s fitness state.”

    From Wearable biosensors for healthcare monitoring (2019) · cites this paper as [145]

  • The chronoamperometric response of lactate in the presence and absence of physiological concentrations of ascorbic acid and UA showed that these potential interferences had a negligible effect upon the lactate response and that the biosensor system provided high selectivity to measure lactate in a noninvasive manner.

    “The chronoamperometric response of lactate in the presence and absence of physiological concentrations of ascorbic acid and UA showed that these potential interferences had a negligible effect upon the lactate response and that the biosensor system provided high selectivity to measure lactate in a noninvasive manner.”
  • Researchers incorporated an amperometric enzymatic biosensor in polymeric mouthguards for monitoring salivary lactate and UA concentrations.

    “Researchers incorporated an amperometric enzymatic biosensor in polymeric mouthguards for monitoring salivary lactate (Fig. 1a–c) and UA concentrations14 (Fig. 1d, e).”
  • The mouthguard lactate biosensor displayed a very high sensitivity toward lactate, with current-signals proportional to the lactate concentration.

    “Data from chronoamperograms for increasing concentrations of lactate in phosphate-buffered saline medium showed that the biosensor displayed a very high sensitivity toward lactate, with current-signals proportional to the lactate concentration.”

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.
