“…Reflecting the literature, Mahjouri‐Samani et al reported response curves composed of a fast time component (25 ms plasmonically enhanced; 100 ms CNT‐only) and a slow time component (≈400 ms) . Here, our achieved response times of t 0 ≈ (9 ± 4) s (according to a cursory evaluation of Figure B–D) fall short of the lithographically achieved plasmonic SWNCT sensors from the literature but are in the same order of magnitude with the response times reported for sensors made likewise from CNT‐based nanoconjugates with metal nanoparticles discussed above (see Supporting Information, Section S0.1, Table SI).…”

“…Enhancement of Raman signals of Au nanoparticles is seen by the SPPs of a metallic CNT as the localized SPPs of the Au nanoparticle couple to the SPPs of CNTs . A literature review on sensor concepts for CNT nanoconjugates from literature including their nanoelectronic or optoplasmonic working principles is presented in the Supporting Information, Section S0.1. Key finding for our work was the fact that, especially for optoplasmonic gas sensing applications, integration times of minutes are reported, with 100 s used as a standard.…”

The authors propose an on-chip microfluidic flow chemistry for non-covalent functionalization of single-walled carbon nanotubes (SWCNTs) as channel material in nanoelectronic carbon-nanotube field-effect transistors (CNT-FETs) specifically aiming for personalized optoplasmonic sensor solutions. Applying pyrene alkanethiol derivatives, dissolved in chloroform, and a dispersion of gold nanoparticles in triglyme, the authors conduct the proof-of-principle to fabricate arrays of photosensitive CNT-FETs using flow chemistry on wafercompatible hardware. The spectral photoresponse of the obtained sensor devices appears clear and reproducible and can be related to the surface plasmon polaritons of the gold nanoparticles. The sensor devices yield photometric responsivities of R A % 8 Â 10 À3 AW À1 and response times of t 0 % 9 s. The results extend a previously reported approach for covalent functionalization (Blaudeck et al., Microelectron. Eng. 2015, 137, 135) and show the potential of flow chemistry combined with wafer-level microfabrication for selectively functionalized nanostructured sensor arrays.

Copper oxide (CuO)-decorated cerium oxide (CeO2) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The sensor responses of electrodes to glucose were investigated via an electrochemical method. The CuO/CeO2 nanocomposite exhibited a reasonably good sensitivity of 2.77 μA mM−1cm−2, an estimated detection limit of 10 μA, and a good anti-interference ability. The sensor was also fairly stable under ambient conditions.

“…Some oxidizable species, such as urea, uric acid (UA), aspartic acid (AP), ascorbic acid (AA), and dopamine (DP) usually co-exist with glucose in practical samples. Thus, the selectivity of the MnO x -30 electrode plays an important role in its sensing performance [24,28]. The concentration of glucose in normal human blood is nearly 20 times greater than the concentration of urea, UA, AP, AA, or DA, and the amperometric response of the MnO x -30 electrode upon addition of 1 mM glucose and 0.1 mM interferent species was examined in 0.1 M NaOH solution.…”
