“…As shown in Figure S2B, the energy band between 166 and 172 eV can be attributed to the S 2p band of the sulfur atom in the PSS, while the energy band between 162 and 166 eV corresponds to the sulfur in the PEDOT. 47,48 After PEDOT:PSS coating, the S 2p peak of PEDOT:PSS can be observed compared to bare paper. Further, in order to confirm the uniformity of the surface of the PEDOT:PSS paper, the sample was characterized by energy dispersive X-ray spectrometry (EDS), and the result confirmed the uniformity of PEDOT:PSS (Figure S2C−E).…”

A self-powered temperature sensor based on Seebeck effect transduction was designed for photothermal−thermoelectric coupled immunoassay of α-fetoprotein (AFP). In this system, glucose oxidase (GOx)-conjugated detection antibody was first captured onto the microplate by target-induced sandwich-type immunoreaction. Thereafter, the as-generated hydrogen peroxide via the GOx−glucose system oxidized 3,3′,5,5′-tetrametylbenzidine (TMB) into photothermal product oxidized TMB (ox-TMB). Under near-infrared (NIR) laser irradiation, the temperature change of ox-TMB was read out in an electrical signal by the flexible thermoelectric module in a 3D-printed integrated detection device. Under optimal conditions, the photothermal−thermoelectric coupled immunoassay exhibited a limit of detection of 0.39 ng mL −1 AFP over a dynamic linear range from 0.5 to 60 ng mL −1 . Impressively, such a strategy presented herein offers tremendous potentials for applying many other high-efficiency thermoelectric materials in ultrasensitive biosensors.

“…[118] Moreover, Kim et al enhanced screening effect of PEDOT:PSS film by doping with Pyronin-B and achieved a significant enhancement of the conductivity to 1467 S cm À1 comparing with that of the pristine film (1 S cm À1 ) (Figure 12b). [119] Similar to carbon and metal electrodes, hybrid strategy is also an effective method to improve the polymer film conductivity. Park et al introduced bilayer electrodes based on PEDOT:PSS and SWNTs chemically modified by HNO 3 treatment and an impressive conductivity of 2438 S cm À1 with transmittance of 88.7% was achieved.…”

In this paper, silver nanowires (AgNWs) with a diameter of 40 nm and a length of 45 μm were dispersed into an ethanol solution to prepare AgNW solutions with concentrations of 1, 2, and 3 mg/mL, respectively. The AgNW solutions were then deposited on a glass substrate using spin-coating at 1000, 2000, and 3000 rpm for 45 s, respectively, to prepare transparent electrodes. The results showed that the distribution of AgNWs on the substrate increased in density with the increase in the AgNW solution concentration and the decrease in spin speed. The effect of concentration on the distribution of AgNWs was greater than that of the spin speed. The transmittance of each electrode was between 84.19% and 88.12% at 550 nm, the average sheet resistance was between 20.09 and 358.11 Ω/sq, the highest figure of merit (FoM) was 104.42, and the lowest haze value was 1.48%. The electrode prepared at 1000 rpm with a concentration of 2 mg/mL and that prepared at 3000 rpm with a concentration of 3 mg/mL were very similar in terms of the average sheet resistance, transmittance at 550 nm, FoM, and haze value; thus, these two electrodes could be considered equivalent. The haze value of the electrode was positively correlated with the spin speed at low concentration, but that relationship became inverse as the concentration rose. For the AgNWs used in this experiment with an aspect ratio of 1125, the concentration of the AgNW solution should reach at least 2 mg/mL to ensure that the FoM of the electrode is greater than 35.
