“…However, it has been known that the detection limit of bioelectronic noses depends not only on measurement technique and detecting instruments, but also on signals obtained from biological elements. [32][33][34] Thus, it can be assumed that enhancing original biological signals will improve the odorant detection of bioelectronic noses, especially olfactory cell-based biosensors. In our study, we showed the design of a nanoparticle-equipped biosensor for odorant detection.…”

Bioelectronic noses, such as olfactory cell-and receptor-based biosensors, have important applications for biomimetic odorant detection in various fields. Here, a nanoparticle-equipped biosensor was designed to record extracellular potentials from olfactory receptor cells effectively. In this research, a microelectrode array (MEA) was combined with olfactory epitheliums as the olfactory biosensor to record electrophysiological signals of receptor cells in the epitheliums. Zinc nanoparticles (NanoZn) were employed along with the biosensor for different kinds of odorant measurements, which improved the electrophysiological responses to odor molecules. The NanoZn-equipped biosensor showed greater performance, such as a higher sensitivity and a larger signal-to-noise ratio, than that without the nanoparticles. Thus, this approach provided a promising method to improve the detecting performance of biosensors based on olfactory cells and receptors, which would bring broad application prospects for bioelectronic noses in environmental monitoring, food analysis, and healthcare diagnosis.

“…Improvement of Cantor-2 can be expected for both sampling efficiency and mass resolution. Sampling efficiency can be enhanced by increasing the EP voltage [24] or the sampling area without increasing the resonator mass, e.g., by using a cantilever array [14] or nano patterning the cantilever surfaces [31,32]. Mass resolution can be improved by reducing the cantilever mass without loss of sampling area, i.e., by reducing the cantilever thickness and by enhancing the frequency stability towards 10 À7 e10 À8 [28], e.g., using higher resonance modes.…”

“…Therefore, future participatory airborne NP monitoring networks based on low-cost, portable, and wireless-connected sensors may rely on such M/NEMS-based devices providing massconcentrations rather than number or surface concentrations. However, their active area is small and efficient self-actuation and sensitive self-detection as prerequisite to mobile operation are a challenge [14]. Correspondingly, nano string resonators on which NPs can be trapped by impaction still require external vibration excitation using a shaker and detection using a laser Doppler vibrometer [15].…”

“…Resonant devices based on micro/nanoelectromechanical systems (MEMS/NEMS) span a broad spectrum of important applications, including chemical detection [1][2][3][4][5][6][7], biosensing [2][3][4][6][7][8][9][10], rheological measurement [11][12][13][14], and energy harvesting [15][16][17]. However, many of these applications require liquid-phase operation, which poses significant challenges due to the drastic reduction in resonant frequency ( res ) and quality factor (Q) that is typically caused by the liquid's inertia and viscous energy dissipation [18][19][20][21].…”

Abstract:To overcome the detrimental effects of liquid environments on MEMS resonator performance, the in-fluid vibration of a novel disk resonator supported by two electrothermally-driven legs is investigated through analytical modeling and the effects of the system's geometric/material parameters on the dynamic response are explored. The "all-shear interaction device (ASID)" is based on engaging the surrounding fluid primarily through shearing action. The theory comprises a continuous-system, multi-modal model and a single-degree-of-freedom model, the latter yielding simple formulas for the fundamental-mode resonant characteristics that often furnish excellent estimates to the results based on the more general model. Comparisons between theoretical predictions and previously published liquidphase quality factor (Q) data (silicon devices in heptane) show that the theoretical results capture the observed trends and also give very good quantitative estimates, particularly for the highest-Q devices. Moreover, the highest Q value measured in the earlier study (304) corresponded to a specimen whose disk radius-tothickness ratio was 2.5, a value that compares well with the optimal value of 2.3 predicted by the present model. The insight furnished by the proposed theory is expected to lead to further improvements in ASID design to achieve unprecedented levels of performance for a wide variety of liquid-phase resonator applications.
