“…Nguyen Minh et al developed an interdigitated electrodes with gaps from 50-250 nm on a silicon wafer (Figure 4c). 101 These nanogap IDEs were then coated with poly(4-vinyl phenol) as the sensing molecular layer for acetone detection. These sensors showed excellent sensing performance with a dynamic range from 10 ppm to 1000 ppm of acetone at room temperature.…”

Electrochemical synthesis has recently emerged as an environmentally benign method for synthesizing value-added fine chemicals. Its unique reactivity has attracted significant interests of synthetic chemists to develop new redox chemistries. However, compared to conventional chemistry, the increased complexity caused by electrode materials, supporting electrolytes, and setup configurations create obstacles for efficient reaction discovery and optimization. The recent increasing adoption of high-throughput experimentation (HTE) in synthetic chemistry significantly expedites the synthesis development. Considering the potential of implementing HTE in electrosynthesis to tackle the challenges of increased parameter space, this short review aims at providing recent advances in the HTE technology for electrosynthesis, including electrocatalysts screening, device miniaturization, electroanalytical methods, artificial intelligence, and system integration. The discussed contents also cover some topics in HTE electrochemistry for areas other than synthetic chemistry, hoping to spark some inspirations for readers to use interdisciplinary techniques to solve challenges in synthetic electrochemistry.

“…Nanocomposites are also a great candidate for being a specific modification material for increasing the selectivity of a gravimetric gas detection system. Researchers have shown that acetone detection can be significantly improved by fabricating polymeric nanocomposites consisting of amine-terminated silicon nanoparticles (Si NPs-NH 2 ) and poly (4-vinylphenol) on a micro-gap interdigitated electrode, and the response of the sensor can be significantly improved by the addition of silicon nanoparticles to the polymer layer [ 131 ].…”

This review paper discusses the advances of the gravimetric detection devices based on capacitive micromachined ultrasound transducers structure. Principles of gravimetric operation and device modeling are reviewed through the presentation of an analytical, one-dimensional model and finite element modeling. Additionally, the most common fabrication techniques, including sacrificial release and wafer bonding, are discussed for advantages for gravimetric sensing. As functional materials are the most important part of the selective gravimetric sensing, the review of different functional material properties and coating and application methods is necessary. Particularly, absorption and desorption mechanisms of functional materials, like methylated polyethyleneimine, with examples of applications for gas sensing and using immune complexes for specific biomolecules detection are reviewed.

“…Furthermore, the addition of nanoparticles often contributes to faster response times of the sensor, due to increased porosity of the sensitive polymeric layer. [27] Although recent studies also reported improvements in the selectivity of hybrid polymer films compared to individual polymers, [28][29][30] there is still not a clear methodology to analyze and predict the contribution of the nanoparticles in the discretization power of polymers and vice versa.…”

Polymeric materials are widely employed for monitoring volatile organic compounds (VOCs). Compared to other sensitive materials, polymers can provide a certain degree of selectivity, based on their chemical affinity with organic solvents. The addition of conductive nanoparticles within the polymer layer is a common practice in recent years to improve the sensitivity of these materials. However, it is still unclear the effect that the nanoparticles have on the selectivity of the polymer membrane and vice versa. The current work proposes a methodology based on the Hansen solubility parameters, for assessing the selectivity of both pristine and hybrid polymer nanocomposites. The impedance response of thin polydimethylsiloxane (PDMS) films is compared to the response of hybrid polymer films, based on the addition of multi-walled carbon nanotubes (MWCNTs). With the addition of just 1 wt.% of MWCNTs, fabricated sensors showcased a significant improvement in sensitivity, faster response times, as well as enhanced classification of non-polar analytes (>22% increase) compared to single PDMS layers. The methodology proposed in this work can be employed in the future to assess and predict the selectivity of polymers in single or array-based gas sensors, microfluidic channels, and other analytical devices for the purpose of VOCs discrimination.
