Abstract: The present disclosure provides a method of fabricating a target capture and sensor assembly. The method comprises the steps of: providing a fluid path with a target capture surface comprising an anchor species with a first functional group disposed thereon; providing a target capture species to the target capture surface of the fluid path, wherein each target capture species comprises a target capture part and a second functional group configured to react with the first functional group; and exposing at least a portion of the target capture surface of the fluid path to photo radiation so as to cause a photo-initiated reaction between the first functional group and the second functional group, wherein the target capture and sensor assembly further comprises a sensing surface in the fluid path and wherein the target capture surface and the sensing surface are in fluid communication with one another.

Abstract: One embodiment is a method for implementing a cloud-based portable miniaturized system for performing non-invasive blood glucose level measurement in real time. The method includes using an optical source to emit optical radiations at certain wavelengths through breath in an air collection chamber; receiving the emitted optical transmissions at a photodetector; converting the received optical transmissions to digital data; accumulating the digital data for a first time period; and periodically transmitting the accumulated digital data to a cloud service for further processing.

Abstract: The present disclosure provides a method of fabricating a sensor assembly in which a sensor surface has an anchor species provided thereon, the anchor species having a first functional group attached. The method further comprises disposing a fluid channel over the surface and subsequently providing an analyte capture species to the fluid channel. The analyte capture species comprises a second functional group configured to react with the first functional group. The surface is then exposed to photo radiation and the first and second functional groups react forming a link between the analyte capture species and the anchor species on the sensing surface.

Abstract: The present disclosure provides a sensor assembly for detecting the presence of at least one amplification product of an isothermal amplification process (i.e., an isothermal nucleic acid amplification process). The sensor assembly includes a first sensor responsive to the detection of an indicator of the presence of at least one amplification product to provide a first signal, the first sensor comprising a sensing surface arranged to contact a sample in the amplification product receiving region, the sensing surface comprises a first layer comprising a one-dimensional or two-dimensional material. Alternatively or additionally, the disclosure provides a pH sensor comprising a sensing surface comprising a first layer comprising a one-dimensional or two-dimensional material.
