“…With the tremendous development in UNCD synthesis and UNCD NW fabrication, many UNCD NW-based sensor applications have been explored, including N-UNCD NW-based methane (CH 4 ) gas sensors [ 73 , 74 ], B-UNCD NW-based carbon monoxide (CO) gas sensor and sensor arrays [ 32 , 75 ], UV sensors based on UNCD NWs functionalized with platinum nanoparticles (NPs) [ 76 ], and piezoresistive B-UNCD NWs. The availability of this special type of DNWs inspires research efforts to make use of both the unique physicochemical properties and geometrical advantages for applications in electrochemical sensors, biosensors, optoelectronics, and nanophotonics.…”

The aim of this review is to provide a survey of the recent advances and the main remaining challenges related to the ultrananocrystalline diamond (UNCD) nanowires and other nanostructures which exhibit excellent capability as the core components for many diverse novel sensing devices, due to the unique material properties and geometry advantages. The boron or nitrogen doping introduced in the gas phase during deposition promotes p-type or n-type conductivity. With the establishment of the UNCD nanofabrication techniques, more and more nanostructure-based devices are being explored in measuring basic physical and chemical parameters via classic and quantum methods, as exemplified by gas sensors, ultraviolet photodetectors, piezoresistance effect-based devices, biological applications and biosensors, and nitrogen-vacancy color center-based magnetic field quantum sensors. Highlighted finally are some of the remaining challenges and the future outlook in this area.

“…After annealing, the adsorbates are freed from the NW surface and the electron transport tunnels within the UNCD's grain boundaries are therefore released and electrons can transfer more freely. The electrical characterization reveals that N-UNCD NWs are stable ohmic semiconductor with environment-sensitive grain boundaries whose conductivity can be altered by gas/vapor adsorption on the surface [74]. This property makes it possible to build N-UNCD NW based chemical/biological sensors, and NEMS based integrated multifunctional sensors.…”

“…(c) Responsivities from the external pair of electrodes to methane down to 2 ppm. Reprinted with permission from[74]; © 2020, IAAM-VBRI.The response and recovery time determined from Figure 17a are 3 and 9 seconds, respectively, which are based on the time duration from 10% to 90% of the full response of the sensor, or vice versa. The obtained response and recovery time are much shorter than the reported values from regular sensors in the range of ~100 s for the response time and > 200 s for the recovery time[79].…”
