Abstract

Direct interfacing of nanosensors onto biomaterials could impact health quality monitoring and adaptive threat detection. Graphene is capable of highly sensitive analyte detection due to its nanoscale nature. Here we show that graphene can be printed onto water-soluble silk. This in turn permits intimate biotransfer of graphene nanosensors onto biomaterials, including tooth enamel. The result is a fully biointerfaced sensing platform, which can be tuned to detect target analytes. For example, via self-assembly of antimicrobial peptides onto graphene, we show bioselective detection of bacteria at single-cell levels. Incorporation of a resonant coil eliminates the need for onboard power and external connections. Combining these elements yields two-tiered interfacing of peptide-graphene nanosensors with biomaterials. In particular, we demonstrate integration onto a tooth for remote monitoring of respiration and bacteria detection in saliva. Overall, this strategy of interfacing graphene nanosensors with biomaterials represents a versatile approach for ubiquitous detection of biochemical targets.

  • This contact lens sensor provided readouts up to 288 measurements within 24 h.

    “This contact lens sensor provided readouts up to 288 measurements within 24 h.”

    From Wearables in Medicine (2018) · cites this paper as [54]

    The tooth-platform figure describes a graphene wireless sensor transferred onto a tooth, not a contact lens. The References section lists a separate contact-lens study, but our copy does not report 288 measurements in 24 hours for that study or for this sensor. (LLM, conf=0.87)

    Checked by a reasoning model — may be wrong.

  • Sensimed AG has introduced a contact lens sensor (Triggerfish) that holds Class IIa CE approval.

    “Sensimed AG has introduced a contact lens sensor (Triggerfish) that holds Class IIa CE approval.54”

    From Wearables in Medicine (2018) · cites this paper as [54]

    The Introduction and References (pages unavailable) discuss biointegrated sensors and cite a different contact-lens sensor for tear glucose. Searches for Sensimed AG, Triggerfish, and Class IIa CE approval found no passage addressing the claimed product or its approval. (LLM, conf=0.77)

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.
