Abstract
An implantable nanosensor includes a stent to be implanted inside a fluid conduit. The stent has a well in a surface of the stent. The implantable nanosensor further includes a nanoscale-patterned sensing substrate disposed in the well. The nanoscale-patterned sensing substrate is to produce an optical scattering response signal indicative of a presence of an analyte in a fluid carried by the fluid conduit when interrogated by an optical stimulus signal.
Claims15
An implantable nanosensor comprising:
- a stent to be implanted inside a fluid conduit, the stent having a well in a surface of the stent;
- and
- a nanoscale-patterned sensing substrate disposed in the well, the nanoscale-pattered sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte in a fluid carried by the fluid conduit when interrogated by an optical stimulus signal.
A nanosensor system comprising:
- an implantable nanosensor comprising a stent having a well and a nanoscale-patterned sensing substrate disposed in the well, the nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte;
- and
- an optical interrogator comprising an illumination source and a signal detector, the illumination source to illuminate the nanoscale-patterned sensing substrate with an optical stimulus signal, the signal detector to detect the optical scattering response signal,
- wherein the implantable nanosensor is to be implanted inside a fluid conduit, one or both of the illumination source and the signal detector being external to the fluid conduit.
A method of in vivo sensing using an implantable nanosensor, the method comprising:
- illuminating the implantable nanosensor within a fluid conduit using an illumination source, the implantable nanosensor comprising a stent having a well and a nanoscale-patterned sensing substrate disposed in the well, the illuminated nanoscale-patterned sensing substrate producing an optical scattering response signal indicative of the presence of an analyte;
- and
- receiving the optical scattering response signal using a signal detector,
- wherein one or both of the illumination source and the signal detector are located external to the fluid conduit containing the implantable nanosensor.
