CA_3100396_A1

Resumen de: US2019352819A1

A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

Resumen de: AU2019275116A1

In one aspect, the present teachings provide a sensor for detecting troponin, e.g., cardiac troponin in a patient's blood, that relies on an electronic signature generated via interaction of troponin with an anti-troponin antibody. More specifically, as discussed in more detail below, such a sensor can include a graphene layer disposed on an underlying substrate, where the graphene layer has been functionalized with an anti-troponin antibody. The interaction of troponin in a sample, e.g., a patient's blood, with the anti-troponin antibody coupled, e.g., anchored, to the graphene substrate, can modulate an electronic property of the underlying graphene layer. The modulation of the electronic property of the graphene layer can be measured and used to identify, and in some embodiments quantify, troponin in the sample.
