“…Thanks to the particular dynamics of the LIFT of liquids, as well as to the rough surface of the electrodes, biomolecule immobilization was possible without the need of any intermediate functionalization step. Another example of biosensor fabrication using LIFT is provided by the demonstration of a bio‐electronic artificial nose for the detection of volatile odorant molecules to identify the presence of contaminants in food . Solutions containing different types of odorant‐binding proteins were printed on surface acoustic wave resonators, which showed a sensitivity and selectivity to the detection of volatile carvone and octenol similar to sensors fabricated with more conventional printing techniques.…”

Laser‐induced forward transfer (LIFT) is a digital printing technique that uses a pulsed laser beam as the driving force to project material from a donor thin film toward the receiving substrate whereon that material will be finally deposited as a voxel. This working principle allows LIFT to operate with both solid and liquid donor films, which provides the technique with an unprecedented broad spectrum of printable materials, and thus makes it very competitive over other digital technologies, like inkjet printing. It is not only that LIFT can access a much wider range of ink viscosities and loading particle sizes; the possibility of printing from solid films allows the single‐step printing of multilayers and entire devices, and even makes possible 3D printing. This versatility translates, in turn, into a broad field of applications, from graphics production to printed electronics, from the fabrication of chemical sensors to tissue engineering. This monograph provides an extensive review of the LIFT technique, from its origins to the most recent achievements, focusing on the fundamental aspects of both its working principle and transfer dynamics, as well as on its broad range of applications.

“…OBPs' function requires humidity, and most of the olfactory sensors developed with these proteins to date perform detection in liquid. However, some results show that their use in artificial noses may be possible ( Figure 2c) [16,[39][40][41][42][43].…”

Artificial noses are broad-spectrum multisensors dedicated to the detection of volatile organic compounds (VOCs). Despite great recent progress, they still suffer from a lack of sensitivity and selectivity. We will review, in a systemic way, the biomimetic strategies for improving these performance criteria, including the design of sensing materials, their immobilization on the sensing surface, the sampling of VOCs, the choice of a transduction method, and the data processing. This reflection could help address new applications in domains where high-performance artificial noses are required such as public security and safety, environment, industry, or healthcare.

“…The resulting array was successfully applied to selectively detect three CWA simulants and the CWA sarin [155]. The same array setup but with three types of odorant-binding proteins instead of polymers was utilized to differentiate between a terpenoid and a mushroom alcohol, which could be used to assess indoor air-quality or food contamination [33].…”

Bulk acoustic wave (BAW) and surface acoustic wave (SAW) sensor devices have successfully been used in a wide variety of gas sensing, liquid sensing, and biosensing applications. Devices include BAW sensors using thickness shear modes and SAW sensors using Rayleigh waves or horizontally polarized shear waves (HPSWs). Analyte specificity and selectivity of the sensors are determined by the sensor coatings. If a group of analytes is to be detected or if only selective coatings (i.e., coatings responding to more than one analyte) are available, the use of multi-sensor arrays is advantageous, as the evaluation of the resulting signal patterns allows qualitative and quantitative characterization of the sample. Virtual sensor arrays utilize only one sensor but combine it with enhanced signal evaluation methods or preceding sample separation, which results in similar results as obtained with multi-sensor arrays. Both array types have shown to be promising with regard to system integration and low costs. This review discusses principles and design considerations for acoustic multi-sensor and virtual sensor arrays and outlines the use of these arrays in multi-analyte detection applications, focusing mainly on developments of the past decade.
